Indonesian Coffee Varieties Explained: From Typica to Tim Tim (Complete Guide)

 Indonesia has long been one of the world’s top five coffee-producing countries, reaching an output of around 11 million 60-kg bags in 2024. Coffee cultivation here dates back to 1699, when it was first introduced by Dutch colonial merchants. In the late 19th century, coffee leaf rust severely impacted production, and these islands quickly became a testing ground for the fungus-resistant variety Coffea canephora (commonly known as Robusta). Liberica and Excelsa were also introduced in an ongoing effort to improve resilience and genetic diversity.

Today, the Indonesian archipelago remains highly relevant in modern coffee production. Regions such as Java, Sumatra, Sulawesi, Bali, and Flores combine rich botanical resources, a long history of cultivation, and proximity to rapidly growing Asian coffee markets. Although these areas remain vulnerable to climate change, unpredictable weather, typhoons, and earthquakes, they are expected to sustain production well into the foreseeable future.

As a result, Indonesia has developed a uniquely diverse set of coffee varieties and a distinct vocabulary around them. Drawing from a compiled reference I came across, let’s take a closer look at some of the major coffee varieties grown locally in Indonesia.


1. Abyssinia

Mentioned in A Review of Indonesian Coffee Research Literature as “Abyssinia Arabica,” this variety was introduced in 1928 from mother trees in what was then referred to as the “Abyssinia Estate” (modern-day Ethiopia). Eleven selections were brought to Indonesia and numbered, with seven (AB1–AB7) released. Among them, only AB3 is still locally referred to as “Abyssinia” (or variants like “Adsenia” or “Abissinie”).

AB3 later traveled from Java to Cameroon, where its genetic lineage was preserved, and eventually made its way to Costa Rica before spreading throughout the Americas. Morphologically, it resembles Typica and is often mistaken as related, but genetic identification by World Coffee Research confirms its Ethiopian origin. Globally, AB3 is better known as “Java.”



2. Andungsari

This variety was selected in 1982 by the Indonesian Coffee and Cocoa Research Institute (ICCRI) in East Java through agronomic trials that lasted about 17 years, evaluating yield, quality, and other factors. It was officially released as a commercial variety in 1999. Named after the Andungsari experimental station where it was developed, this composite variety is typically grown at high altitudes between 1,400 and 1,700 meters, allowing for slower cherry maturation and richer flavor development.

Andungsari combines desirable traits from multiple parent lines, offering leaf rust resistance, high yield, and excellent quality. It provides more stable income for farmers while delivering a distinctive Indonesian flavor experience. Under washed processing, it is said to produce an exceptionally juicy cup with black tea and floral notes, challenging the traditional perception of Indonesian coffee as heavy but lacking acidity. When naturally processed, it exhibits wine-like aromas, maple syrup sweetness, and greater body with complex flavor layers.

3. Ateng
Ateng holds a role in Indonesia similar to Caturra in Colombia. The name is derived from “Aceh Tengah,” and it is typically grown at lower altitudes, often not regarded as a high-quality variety. Rather than being a distinct new variety, Ateng is a localized name for Catimor-type cultivars in Indonesia. In Indonesian, “Ateng” means “small,” referring to its compact plant structure.

Its genetic makeup blends Arabica and Robusta, giving it strong resilience. It is widely cultivated across major Arabica-producing regions, especially Aceh, Lintong, and West Java. Under traditional wet-hulling processing, Ateng produces classic Mandheling characteristics: herbal, spicy, with notes of dark chocolate, pine, and caramel, a heavy body, and low acidity. However, when grown at higher altitudes and processed carefully, it can reveal surprising potential, including stone fruit notes like peach and apricot, along with a cleaner profile.


4. Bergendal

Bergendal is the local name in Sumatra for one of Indonesia’s oldest and most classic Typica lineages. If Ateng represents the “modern force” of Indonesian coffee, Bergendal is the time-honored “classical aristocrat.” Introduced by the Dutch from India to Java in the late 17th century and later spread to larger islands like Sumatra, Bergendal is a direct descendant of this early Typica lineage.

The name comes from Dutch—“Berg” meaning “mountain” and “Dal” meaning “valley”—aptly describing its growing environment. Unlike Ateng, Bergendal has no Robusta ancestry and remains a pure, traditional Arabica lineage, preserving the elegant flavor profile of classic Typica. It is known for low acidity, subtle fruitiness, and layered herbal and spice aromas, offering a balanced and gentle cup.


Bergendal is like a reclusive master craftsman—low yielding, but every bean carries centuries of flavor heritage. If you’re looking for a cup that combines the richness of classic Mandheling with a cleaner and more refined profile, lots containing Bergendal are an excellent choice.


5. Blawan Pasumah

This is a uniquely positioned variety in Indonesia’s coffee family tree. It is neither purely Typica nor Catimor, but rather a carefully selected local cultivar combining a Typica backbone with USDA lineage. In simple terms, it can be seen as an Indonesian version of a “refined Typica”—retaining classic flavor genetics while offering improved adaptability and commercial value.

The name reflects its origin: “Blawan” refers to the historic Blawan Estate in East Java, a Dutch colonial-era plantation where the variety was developed and promoted. “Pasumah” traces back to its original naming by Dutch botanist P.J.S. Cramer. After further selection and stabilization at Blawan, it became known as Blawan Pasumah.

Its USDA lineage refers to coffee varieties distributed globally by the U.S. Department of Agriculture, often selected for disease resistance and yield potential. As such, Blawan Pasumah is essentially a Typica-based selection enhanced with USDA genetic improvements, aiming to balance traditional flavor with modern agricultural needs. In the cup, it is typically cleaner than standard Mandheling, with reduced herbal notes and enhanced floral tones, fruit sweetness, and delicate acidity.


6. Borbor

Borbor has emerged in recent years as a highly regarded “star variety” from Sumatra. Although it has not undergone formal genetic verification, experts generally believe it may be a hybrid involving Tim Tim (Timor Hybrid) and Bourbon.

Under Indonesia’s traditional wet-hulling process, Borbor produces intensely rich and complex spice notes—clove, pepper, and tobacco—along with a heavy body and remarkable depth. If you’re seeking a coffee that represents Indonesia’s signature bold spice profile while meeting high specialty standards, a Borbor lot from Aceh is unlikely to disappoint.


7. Tim Tim

This is one of the varieties I’m most familiar with and have tasted frequently. Tim Tim is the Timor Hybrid, a natural cross between Arabica and Robusta discovered in the 1940s on Timor Island. It is known for its large, elongated beans—so large that even after roasting, they remain noticeably oversized, earning it the nickname “long-bean Mandheling.”

This variety emerged through natural hybridization and selection, and its strong disease resistance led to widespread cultivation.



8. Kartika

Kartika is a hybrid of Timor Hybrid 832/1 and Caturra, introduced to Indonesia in 1987 as part of Portuguese multi-location trials. It represents a somewhat “bittersweet” chapter in Indonesia’s coffee breeding history. Initially developed to combine disease resistance and high yield, it was once promoted as a flagship variety in 1993.

However, resistance is never permanent. As leaf rust evolved, it eventually overcame Kartika’s defenses. Today, it is no longer recommended for smallholders, illustrating a microcosm of modern coffee cultivation—where breeding successes can be temporary in the face of evolving pathogens.


9. S.795

Originally developed in India, S.795 is widely known in Indonesia as “Jember,” named after the research station in East Java where it was introduced in 1955. It is one of the foundational varieties for high-quality coffee production across Sumatra and Java.

Developed in the 1940s by India’s Central Coffee Research Institute (CCRI), S.795 has a complex lineage: Kent (a Typica mutation from India) crossed with S.288 (a natural hybrid involving Liberica and Arabica). By combining Kent’s flavor and disease resistance with the robustness of S.288, S.795 achieves a well-balanced profile while eliminating the undesirable “animal-like” notes often associated with Liberica. It stands as a successful example of cross-border breeding, proving that hybrid varieties can deliver disease resistance, high yield, and excellent cup quality.


10. P88

P88 belongs to the Catimor group and is a distant relative of Ateng. While both share Catimor ancestry, P88 was developed through more systematic international breeding programs, giving it a clearer and traceable lineage.

Introduced by the Dutch in the 1980s as part of variety trials, P88’s journey spans Kenya, Colombia, Thailand, and Indonesia. It inherits disease resistance from Timor Hybrid and the yield and flavor traits of Caturra. If Ateng is Indonesia’s localized “field performer,” P88 is the internationally bred “top student” that has successfully adapted and thrived in Indonesian conditions.



11. Sigarar Utang

This variety has one of the most striking names in Indonesia’s coffee world—literally translating to “the debtor must die.” Behind it lies a folk story about debts repaid either in money or coffee trees. Despite its intimidating name, Sigarar Utang is known for its remarkably sweet and elegant flavor.

It is a signature variety in Java and West Sumatra specialty coffee, recognized for its clean, refined profile. Most notably, it breaks away from the traditional Indonesian profile of herbal, heavy, low-acid coffee, instead offering a bright, clean cup with vibrant fruit notes.



12. USDA 762

USDA 762 is a heritage variety originating from Ethiopia’s wild forests, introduced by the U.S. Department of Agriculture and later flourishing in Indonesia. The number “762” is shorthand for its full USDA plant introduction code, PI 230762.

On December 20, 1955, French researcher J.B.H. Lejeune, working with the FAO, collected these wild coffee seeds in the Mizan Tafari region of Ethiopia’s Kaffa forest—very close to the origin of Gesha. After being sent to the U.S. and cataloged by the USDA, the seeds were distributed globally to research institutions, including Portugal’s Coffee Rust Research Center (CIFC) and Indonesian research bodies.

In recent years, USDA 762 has gained popularity in the specialty coffee world due to its exceptional flavor profile. It challenges traditional expectations of Indonesian coffee, showcasing elegance and clarity more commonly associated with Ethiopian lineage.

Does Expensive Coffee Really Taste Better? The Truth You Should Know

 People often say, “You get what you pay for.”

In many aspects of life, this saying makes perfect sense, and it’s deeply ingrained in the way we think about consumption.

Not long ago, a customer came into our shop for coffee. After looking at the menu, he asked with surprise, “What’s this Emerald Red Label for 75 yuan? It must taste way better than the regular pour-over for 30 yuan, right?”
Clearly, this customer had already equated “expensive coffee” with “good coffee,” assuming that a higher price always means better flavor.
But is that really the truth?

What determines the price of coffee?

1. Variety

Most people know that the coffee beans sold today are broadly divided into Arabica and Robusta.

Arabica includes many sub-varieties—Typica, Bourbon, Caturra, and more. These beans are usually grown at high altitudes above 800 meters. They tend to have a smoother taste and more refined flavor characteristics influenced by the local terroir.
However, Arabica is picky by nature. It demands a high-quality growing environment, has lower yields, is more vulnerable to pests and disease, and can even wither easily. Farmers must invest more time and resources into maintenance, which naturally raises the price.

Robusta, on the other hand, grows mainly below 800 meters. It's hardy—resistant to pests, tolerant of heat and direct sunlight, and suitable for dense planting. Its yield per harvest can be very high, making it widely available across many countries. Because of this abundance, Robusta is commonly used in dark espresso blends and instant coffee at a lower cost.

2. Green Bean Grading

No matter how pricey a cup of coffee is or how it’s brewed, coffee beans are ultimately an agricultural product. And like all agricultural products, each producing country has its own grading standards. The higher the grade, the higher the price.

Globally, coffee grading systems generally fall into three categories:
bean size, altitude (bean hardness), and defect count.

For example:

  • Regions like Kenya and Colombia sort beans by size using screens. Larger beans are believed to ripen more evenly and develop better flavor, making roasting more consistent.

  • Panama, Costa Rica, and Guatemala grade beans by altitude. Higher altitude means denser beans, richer nutrients, and more pronounced flavor—thus higher value.

  • Ethiopia and Indonesia classify beans by defect rate. The fewer defects, the more valuable the coffee. For instance, our PWN Golden Mandheling undergoes machine sorting once and hand sorting three times, reducing defects to a minimum and significantly increasing its price.

Beyond national standards, some well-known estates have developed their own grading systems.
The most famous is Panama’s Hacienda La Esmeralda, whose Geisha beans are labeled Red Label, Green Label, and the exclusive Auction Lot—each grade more expensive than the last, especially the rare auction batches.

3. Yield and Scarcity

There’s an old saying: Scarcity creates value.
Coffee is no exception.

Take Jamaica Blue Mountain, once known as the “Hermès of the coffee world.”
To standardize quality, the Jamaican Coffee Board designated a specific region in the Blue Mountains where only Typica beans grown within that boundary can be called “Blue Mountain Coffee.”
This official growing area is only about 6,000 hectares—just one-third of the entire mountain region.

Typica already has low yields, and the high-altitude environment makes harvesting even more labor-intensive. Add in strict quality control and later hype from Japan, and the price skyrocketed. In the early days—before cafés became common—a single cup could cost over 1,000 yuan.

Today, with direct imports to China, prices have become more accessible. For example, you can now enjoy a classic Blue Mountain pour-over at our shop for 60 yuan.

Higher prices don’t automatically make a coffee “better”

From everything we’ve listed above, it’s clear that industry standards create natural price differences. But for consumers, the value of a cup of coffee isn’t determined by price—it’s determined by whether it suits your taste.

We once had a regular customer who loved dark-roast coffee. One day, she decided to splurge on a cup of our premium Geisha.
But after just one sip, she frowned and said, “Too sour. Not ordering this again.”

Different origins, farms, varieties, processing methods, grades, and roast levels all shape the flavors listed on a bag of coffee. When buying beans or ordering a drink, most people start by choosing what they prefer:

  • If you like bright acidity, you can enjoy something affordable like Yirgacheffe—or go all-in with an expensive auction Geisha.

  • If you like bitterness or a fuller body, Blue Mountain is an iconic (and pricey) option—but a budget-friendly Brazilian bean can offer similar satisfaction.

That’s why we believe:
Expensive coffee and good coffee are not the same thing.
The best coffee is simply the one that matches your personal taste.

Coffee for Beginners: The 6 Essential Tips Every New Coffee Lover Should Know

 Have you ever found yourself standing in front of a shelf of coffee beans, staring blankly at all the different packages? Or maybe when a friend asks what kind of coffee you like, all you can say is, “Uh… anything that smells good”? Don’t worry—every seasoned coffee lover started out just as confused.

Today, let’s walk through six key tips for getting into coffee, helping you avoid detours and find your perfect cup faster.

1. Get to Know Coffee Beans

Coffee beans are actually the seeds of the coffee cherry. Globally, they’re mainly divided into two categories: Arabica and Robusta.
Arabica beans are delicate and bright, with higher acidity, while Robusta beans offer a stronger, more intense flavor and higher caffeine content.
When you’re shopping, start by trying Arabica—after all, it makes up more than 70% of the world’s coffee production.

A coffee’s flavor largely depends on its origin—much like wine. Ethiopian beans often have floral and fruity notes, while Brazilian beans tend to be sweeter and nuttier. Try a few single-origin coffees from different regions and slowly discover what you love.

2. The Art of Grinding

There’s an old saying in the coffee world: “Freshly ground is king.”
Why? Because once coffee beans are ground, their aromas escape quickly. Think of whole beans as a sealed treasure chest—grinding is the moment you open it, and everything inside begins to fade.

Grind size depends on your brewing method. In short:

  • Shorter brewing time → finer grind

  • Longer brewing time → coarser grind

For example, espresso requires a powdery, flour-like grind, while a French press needs coarse, sea-salt-like particles.

3. Brewing Methods

Different brewing methods offer completely different flavor experiences:

  • Pour-over highlights the bean’s subtle characteristics—great for exploring origins.

  • French press is simple, rich, and full-bodied thanks to the retained oils.

  • AeroPress blends immersion and pressure for a clean, smooth cup.

  • Cold brew uses long, cold extraction, resulting in low acidity and a naturally sweet finish—perfect for summer.

Start with whichever method sounds the most fun to you!

4. Essential Tools

You don’t need a ton of equipment to begin. These basics are enough:

  • A grinder — a hand grinder is totally fine

  • A scale — ensures consistency

  • A brewer — pour-over dripper or French press

  • A thermometer — water temperature matters for extraction

A good grinder is actually more important than a pricey coffee machine. Even grinding makes all the difference.

5. Tasting and Describing Coffee

When you taste coffee, pay attention to:
aroma, acidity, body, and flavor notes.

Coffee acidity isn’t like sourness in food—it’s more like the bright, lively quality you’d find in wine.
Body refers to how the coffee feels in your mouth, from light like water to thick like syrup.

When describing flavors, compare them to familiar tastes:
“This cup has hints of dark chocolate,”
“I’m getting a refreshing citrus note.”

Everyone’s palate is unique—there are no right or wrong answers.

6. Storage Secrets

Coffee beans have four enemies: air, moisture, heat, and light.

Store them in an airtight, opaque container, in a cool and dry place.
Don’t keep them in the fridge—temperature changes cause condensation, which speeds up flavor loss.

Buy whole beans and grind right before brewing.
If possible, buy only as much as you can finish in about two weeks. Freshness is everything.

Coffee is an adventure, and everyone has their own path. Start with a cup you brew with intention, and slowly explore this wonderful world.

Why Your Body Can't Handle Coffee Like Before: A Deep Dive into Beans, Metabolism, and Modern Stress

 As a coffee lover and professional, I’ve been guarding this little, aroma-filled café for four years now.

My bar counter is like a quiet old friend, accompanying countless people through their early mornings and late nights.
Every latte with delicate latte art, every pot of carefully brewed pour-over I handed to customers—what I received in return was the sparkle in their eyes. Coffee was a ritual, a comfort, a silent understanding we all shared.

But over the past one or two years, a subtle shift has taken place around me. Several familiar customers, myself included, have gone through similar changes. Those regulars who used to come once a day now only show up two or three times a week, and eventually only on weekends.

Take Ms. Wang, for example—the advertising director who relied on a double espresso to survive every workday. Now, when she walks in, she orders only a cup of decaf. She laughs and tells me, “It’s not that I don’t want coffee. I still love the fruity notes of Ethiopia and the sweetness of Gesha, but it just feels like my body can’t ‘handle’ coffee anymore.”

Customers like her are growing by the day.
It’s not that they stopped loving coffee—it's that their bodies have started making the choice for them.

Standing behind the bar listening to all this feedback, combined with the changes I’ve observed in the industry, my curiosity pushed me to dig deeper into the truth behind it all.

I began to wonder:
Have we changed, or has coffee changed?
Thinking about it carefully, maybe it’s both.

First of all, the coffee we’re drinking might not be the same coffee as before.
The explosive growth of the coffee market really happened only in recent years. I remember when I first entered the industry, Luckin didn’t have any 9.9 RMB deals. My first cup of Luckin cost around 20 RMB, and I worked in a specialty coffee shop where the roasters roasted meticulously every day, and baristas brewed beans from all over the world with equal care.

Back then, I didn’t even understand coffee varieties. I slowly learned by reading coffee bean labels. (Everything I encountered was Arabica.) The coffees I drank had layered, complex flavors, and the caffeine content was relatively mild. Brewing a whole pot myself felt like a refined enjoyment.

But now, everywhere you look, there’s commercial coffee selling for 8.8, 9.9.
As someone who knows a little bit about coffee, I learned a rather harsh reality: in recent years, green coffee prices have surged, and to survive the price wars, some businesses had no choice but to make adjustments in their beans.

A common method is blending in cheaper Robusta beans—whose caffeine content is nearly double that of Arabica.
(Of course, many industry veterans will say that Robusta has been moving toward specialty coffee too, and prices aren’t necessarily low. But the gap between consumer perception and industry knowledge is huge. I won’t dive into technicalities here—let’s stay focused on the phenomenon.)

You can think of this blending as a form of “caffeine dilution—but in reverse.”
Long-term consumption of high-caffeine, rough-flavored coffee beans means your body is hit with stronger and more singular stimulation. It no longer wakes you up gently—it smacks your nervous system with a hammer.

This might explain why many people now feel more heart palpitations, insomnia, or “hollowed out” after drinking cheap coffee.

Secondly—and more importantly—our bodies are no longer the bodies we had a few years ago.

My bar counter is also a confessional.
I’ve heard far too many of the same whispers:
“It’s so strange. I used to be fine with two cups a day. Now half a cup keeps me tossing and turning at night.”

At first I didn’t understand, until I realized my own tolerance had dropped as well. I started reading research and chatting deeply with customers.

I eventually realized something: whether it’s time or the global health journey we all went through, it left marks inside us.
It likely affected a key factor—the enzyme “CYP1A2” in the liver responsible for metabolizing caffeine.

This enzyme’s activity is like our energy levels—it has its limits.
Its upper limit is determined by genetics, which is why some people can sleep after three cups, while others lose sleep from a single sip.
But its lower limit is greatly affected by our health conditions and medications.

When the body experiences major stress or is in a state of chronic inflammation, this enzyme’s activity may drop. That means the cup of coffee you once metabolized easily now demands more effort and more time.
Excess caffeine that your body can’t break down lingers in the system, and discomfort naturally follows.

On top of that, the environment we live in has become more stressful than ever.

It’s undeniable—society’s overall stress level, especially long-term, chronic anxiety, is much heavier than it was a few years ago. Our bodies live in this “high-pressure chamber” every day, with adrenaline and cortisol levels already elevated.

Then you pour a high-caffeine coffee into this state.
It’s like plucking a string that’s already stretched too tight.
It screeches, or worse, snaps.

And the body’s signal becomes: heart racing, trembling hands, inability to focus, irritability.
This is no longer stimulation—it’s the “last straw that breaks the camel’s back.”

Our bodies are protesting in the most direct way:
They’re exhausted.
They need rest, not stronger stimulants.

Putting all these factors together, I suddenly understood:
It’s not that we’ve become fragile—it’s that our bodies are giving honest feedback under the combined effects of lower bean quality, changes in caffeine metabolism, and increased environmental stress.

That’s why many people—including myself—feel fine drinking coffee years ago but not anymore.
In the end, many people have no choice but to “quit.”

But anyone who’s gone through caffeine withdrawal knows—it’s far from easy.
The symptoms are classic: fatigue, emotional dips, loss of motivation.
Many people get stuck here because the discomfort is too much. Energy recovery may take two weeks or more, and emotional recovery varies by person.

So if we truly love coffee, can’t live without it, and want to drink it more healthily and sustainably under current conditions—what should we do?
Here’s what I’ve learned:

1. Learn to “listen” to the beans
Choose cafés that tell you where their beans come from and how they’re grown.
A carefully brewed pour-over or an espresso with origin transparency usually means the barista understands their beans well.
Even within Arabica, there are commercial grades and specialty grades. Baristas who know their beans will naturally choose gentler Arabica and will sort out moldy or insect-damaged beans that add extra burden to the body.

Within your ability, choose beans with reliable quality and baristas you trust.
You can also reduce brew strength to lighten the load on your body.

2. Schedule “coffee breaks” for your body
Don’t let your body become fully dependent on or tolerant of caffeine.
My approach is “three times a week,” or “drink for two days, rest for two days.”
The idea is to give your body a natural rest-and-recovery cycle, so that your liver enzymes get a break and your nervous system can recalibrate.
When you break the daily-coffee habit, you’ll gain back your sense of control.

3. Actively replenish “high-quality nutrients”
The way caffeine works is by consuming neurotransmitters like dopamine and adrenaline.
Each time you use it, you need raw materials to rebuild.
So increasing high-quality protein intake is like refilling ammunition for your body—beef, lamb, eggs, and fish are all great choices.
This gives your body more resilience when dealing with caffeine’s effects.

As I write this, I’m reminded of something I once said:
Coffee itself isn’t inherently good or bad.

It’s like a knife—it can be a kitchen tool or a weapon.
It all depends on how it’s used.

What matters is understanding how coffee works in your body, being aware of the environment you’re in (bean quality, societal stress), and knowing your true physical condition.

Ultimately, our relationship with coffee should be a clear, autonomous choice—
not a passive dependency.

Want a Stronger Coffee Kick? Choose the Right Beans and Brewing Method

 If you drink coffee to stay alert, you probably know caffeine is the secret behind its energizing effect. But have you ever wondered why some coffees seem to wake you up instantly, while others barely do the trick? The answer lies in two key factors — the type of coffee beans and how you brew them.



☕ Coffee Bean Varieties: Arabica Has Less Caffeine

There are two main types of coffee beans grown commercially around the world: Arabica and Robusta.
Arabica beans contain 0.8%–1.5% caffeine, while Robusta beans have 1.7%–4%, which is nearly double the amount.

Although Arabica makes up more than 70% of the world’s coffee production, the caffeine content in your cup doesn’t just depend on the bean itself — it depends even more on how you brew it.


🔥 Brewing Methods: Drip Coffee Packs the Most Caffeine

A lot of people think that the stronger the coffee tastes, the more caffeine it has — and the more it’ll keep you awake. But that’s not exactly true.

According to coffee expert Han Huaizong, the strength of flavor mainly depends on how much water you use, not the actual amount of caffeine.
Assuming you’re using the same beans, factors like grind size, brewing method, steep time, and water temperature all influence how much caffeine gets extracted.

In short:

  • Finer grind = more caffeine

  • Longer brew time = more caffeine

  • Hotter water = more caffeine


⚖️ Comparing Caffeine Levels by Brewing Method

☕ Drip Coffee (American Style)
Hot water passes through coffee grounds for 5–8 minutes, giving it the highest caffeine content of all brewing methods.
A typical 8 oz (230 ml) cup contains around 115–200 mg of caffeine.

🫖 French Press
Coffee grounds are steeped in hot water (185–198°F / 85–92°C) for 2–4 minutes and stirred, resulting in a high caffeine extraction.

🌫️ Siphon Coffee
Brewed with a siphon pot and stirred as well, but the extraction time is shorter — only 45–60 seconds, so it has slightly less caffeine than French press coffee.


☀️ Final Thoughts

If you’re after a real energy boost, it’s not just about choosing strong-tasting coffee — it’s about choosing the right combination of beans and brewing method.
So next time you’re in need of a serious wake-up, reach for Robusta beans and go for a drip brew — your morning self will thank you.

Vietnam’s Coffee Export Value Hits Record High; Prices Expected to Stay Elevated in the New Season

 As global demand for coffee continues to surge, Vietnam — the world’s largest Robusta producer — is experiencing a historic boom. The country’s coffee export revenue has reached new heights, fueled by strong international prices and robust yields across its fertile Central Highlands. Farmers are optimistic, traders are holding back stocks for better deals, and experts predict that Vietnam’s coffee prices will stay high well into the new season. Here’s a closer look at what’s driving this record-breaking growth and what it means for the global coffee market.



According to data from the Vietnam Coffee and Cocoa Association (VICOFA), Vietnam exported over 1.5 million tons of coffee during the 2024/25 season — a 6% increase compared to the previous year. Export revenue surged to an unprecedented $8.4 billion, up 60% year over year, driven by both higher coffee prices and increased production.

Starting in October, Vietnam entered the 2025/26 crop year, with domestic coffee prices holding steady around 115,000 VND per kilogram (approximately $4.37), about 5,000 VND higher than the same time last year.

On the international market, Robusta coffee futures have stabilized between $4,500 and $4,600 per ton, while Arabica futures have soared to nearly $9,000 per ton, giving Vietnamese Robusta coffee a strong competitive edge.

In the Central Highlands, Vietnam’s largest coffee-growing region, local farmers remain optimistic that prices will stay high for the third consecutive year. Local cooperatives report that even with stable prices, farmers’ income and profits are expected to rise significantly this season.

A local trader also noted that many farmers are holding back their stock, waiting for better prices. In recent years, strong returns from coffee, durian, and pepper have brought greater financial stability, allowing farmers to adopt more strategic selling practices.

Looking ahead, VICOFA forecasts that Vietnam’s coffee output could increase by about 10% in the 2025/26 season, supported by favorable weather conditions and persistently high prices. Additionally, rising Arabica coffee prices from Brazil and Colombia are expected to further boost global demand and pricing for Vietnamese Robusta.

Vietnam’s record-breaking coffee performance underscores its growing influence in the global market. With farmers gaining more control over when and how they sell, and with international buyers increasingly recognizing the quality and reliability of Vietnamese Robusta, the country is well-positioned to strengthen its role as a key player in the global supply chain. If favorable weather and strong prices continue into 2026, Vietnam’s coffee industry could set the tone for the next phase of sustainable growth and economic resilience in the world of coffee.

The Science of Delicious Coffee: How Acids, Sugars, and Alkaloids Shape Every Sip

 


In brewed coffee, over 800 flavor and aromatic compounds have been identified. For coffee enthusiasts, the most exciting part is figuring out how these compounds form and how they influence the flavor and mouthfeel of coffee. There are plenty of books that dive deep into the chemistry of coffee, but for those who aren’t chemists, reading them can be a snooze—even with all the caffeine you consume! So today, we’ll focus only on a few of the main compounds.


Acids and Sugars: The Key to Coffee Flavor

As both roasters and coffee lovers, we’re particularly interested in two types of compounds: carbohydrates (sugars) and organic acids. The interplay between these compounds largely defines the coffee experience. To understand this, just think of the difference between cheap white wine and a decent wine. Cheap wines have low sugar content and only one or two prominent acids, which makes them taste sharp, thin, and harsh. Good wines, on the other hand, have rich acid profiles—some with sweetness and fruitiness—which form the foundation for all the flavors and aromas.





Acids Affect Coffee Quality and Complexity

Green coffee beans naturally contain acids we’re familiar with, such as citric acid (also found in oranges, lemons, and limes) and malic acid (found in apples), as well as some acetic acids formed by the breakdown or reaction of sugars and other compounds.

The quality and complexity of coffee depend on the balance of these acids in the beans. This balance is influenced by a variety of factors, including the coffee variety, mineral content of the soil, temperature, humidity, and roasting level.




In unroasted beans, the main acid is chlorogenic acid, making up 5–10% of the dry weight. It has grassy, bright, or overly sharp flavors and also contributes bitterness. Most chlorogenic acids break down during roasting, forming other acids like caffeic acid and quinic acid. These acids have milder sourness and bitterness and, at lower concentrations, provide a complex, pleasant balance to coffee’s taste.



Sugars: The Main Source of Sweetness

One of the most important sugars in coffee beans is sucrose, which contributes noticeable sweetness to the final brew. During roasting, as the beans darken, sugars break down, which is one reason dark roast coffees taste more bitter and less sweet than light roasts.

Sugar molecules also undergo caramelization and participate in the Maillard reaction with proteins, turning the beans brown and producing a variety of aromatic compounds. Throughout roasting, caramelization and Maillard reactions occur simultaneously. Caramelization produces sweet, caramel-like, buttery, and vanilla aromas, while Maillard reactions create roasted, floral, spicy, and chocolatey notes.


Sucrose content peaks when the coffee cherry is fully ripe, which is why we prioritize beans from hand-picked, fully red cherries. Robusta beans have significantly less sucrose (and chlorogenic acid) than Arabica, which is why roasted Robusta tends to be more bitter and less complex than Arabica.



Alkaloids Complete the Coffee Flavor Profile

Another key group of compounds in coffee is alkaloids. The most famous is caffeine, but there’s also the lesser-known trigonelline. Coffee first caught human attention because of caffeine’s stimulating effects—a major reason why many people drink coffee, and why they crave it.

Caffeine is bitter, and bitterness is an essential part of coffee’s overall flavor profile. Trigonelline is also bitter but partially breaks down during roasting, helping form many aromatic compounds. Its breakdown products include niacin (vitamin B3), with each cup containing 1–3 mg depending on coffee concentration and brewing method. Just a couple of cups can provide your daily recommended intake of 14–18 mg.
