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.

What Does Coffee Brewed with Coconut Water Taste Like?

 The world of coffee never lacks innovation. We’re constantly seeing new and creative combinations made from familiar ingredients. Take coffee and coconut, for instance — this pairing alone can produce countless variations: coconut water + espresso becomes a refreshing coconut Americano; thick coconut milk + espresso makes a creamy coconut latte; and coconut + cold brew creates a tropical iced drink. All of these drinks take simple ingredients and layer them into something new and interesting.

But just yesterday, I stumbled upon another “experimental” crossover — brewing coffee with coconut water. And no, I don’t mean adding coconut water to already brewed coffee, nor using it to mix with instant or freeze-dried coffee. I mean replacing regular brewing water entirely with coconut water when making pour-over coffee.

At first, I frowned at the idea — it sounded a little crazy. But then I thought, if we can boil chicken in coconut water for soup, why not brew coffee with it? Plus, some experienced coffee lovers have given it surprisingly positive reviews. So today, I decided to test it myself.



Preparing the Ingredients

A cup of pour-over coffee is over 98% water, so the water you use plays a major role in determining its final flavor. The same goes for coconut water. I chose fresh young coconuts because their juice is abundant and naturally rich in amino acids, vitamins, and minerals — not to mention it has a sweet, fragrant aroma. Of course, if you want convenience, boxed coconut water will do just fine.

Since coconut water has a distinct sweetness and aroma, I think it pairs best with beans that aren’t roasted too dark or too light. Dark roasts would overpower the delicate coconut notes, while very light roasts tend to be too acidic and may clash with the coconut flavor.

From my bean collection, options like Sidamo Alo, Flower Queen, Strawberry Candy, Tarrazu, Diamond Mountain (Finca Esmeralda), or Geisha Village Chaka all fit the bill. For today’s test, I went with Sidamo Alo — a naturally processed, medium-light roast known for its notes of magnolia, mango, orange, and strawberry.

Ingredients:

  • 3 fresh coconuts

  • A heat source

  • 15g Sidamo Alo coffee beans

From past experience, if you want the fruitiness and coffee flavors to balance, you have to control the brew strength. Too concentrated, and the coffee overwhelms the coconut. So I set the coffee-to-water ratio to 1:16 and divided the total water volume into four pours to optimize flavor extraction.

Brew parameters:

  • Coffee: 15g

  • Ratio: 1:16

  • Water temperature: 91–92°C (195–198°F)

  • Grind size: EK43s – 10 clicks / C40 – 24 clicks (≈80% passing through a 20-mesh sieve)

  • Dripper: V60

  • Pouring method: four stages



Brewing Steps

  1. Open the coconuts and pour all the juice into a kettle. Heat until just below boiling, then let it cool to 91–92°C.

  2. Grind 15g of coffee to a fine sugar-like texture and pour it into a pre-wet filter, flattening the surface gently.

  • Bloom: Start with a 30g circular pour and let it bloom for 30 seconds. A faint coconut aroma will rise.

  • Second pour: Add 90g of hot coconut water in a larger circular motion, reaching 120g total on the scale.

  • Once the coconut water almost drains and the coffee bed is visible (around 55 seconds to 1:05), do the third pour with 60g using a gentle, smaller pour.

  • After that drains, finish with a final 60g pour directly in the center. The total brew time should be around 2 minutes and 10 seconds.

The coffee brewed with coconut water looked slightly cloudy. The aroma was a mix of coconut sugar and roasted coffee. The first sip didn’t taste like coffee at all — more like warm coconut broth with a hint of saltiness, likely from the minerals reacting to heat. After a few sips, the Sidamo Alo notes began to appear: orange, pineapple, peach — but all faint, blurred by the dominant coconut flavor. The result? A cup that tastes more like “coconut-flavored coffee” than coffee with a coconut twist.



Iced Coconut Water Pour-Over

Since I was already at it, I decided to try an iced version too. The parameters were similar to my usual café setup:

Ingredients:

  • 15g Sidamo Alo coffee beans

  • Ratio: 1:10

  • 75g ice cubes

  • Water temperature: 91–92°C (195–198°F)

  • Grind size: EK43s – 9.5 clicks / C40 – 22 clicks (≈82% passing through a 20-mesh sieve)

  • Dripper: V60

  • Pouring method: three stages

Steps:

  1. Put 75g of ice into the server.

  2. Add the ground coffee to the filter.

  3. Pour 30g of coconut water in small circles to bloom for 30 seconds.

  4. Add 60g more using the same gentle motion — don’t pour too hard or you’ll break the coffee bed.

  5. When the coffee almost finishes dripping, pour the remaining 60g of coconut water. Aim for a total brew time of about 1:50–2:00 minutes.

To be honest, the iced version didn’t have any significant flavor advantage either. It tasted mostly of young coconut, citrus sweetness, and a slight black-tea-like note. But thanks to the ice, it was crisp and refreshing — perfect for warm weather, like here in southern China where people are still wearing short sleeves.



Final Thoughts

After two rounds of testing, I’d say brewing coffee with coconut water is a fun experiment, but not something I’d make a habit of. The flavor is interesting but far from balanced. If you’re chasing novelty, it’s worth trying once or twice. But if you’re after pure coffee flavor, it’s really not worth buying coconuts or heating coconut water just to make pour-over coffee — especially since it doesn’t yield great results and cleaning your kettle afterward is a real pain.

Why Japanese Coffee Lovers Prefer Flannel Filters Over Paper

 When it comes to flannel filters, many coffee lovers may have only seen them in Japanese movies or through videos by Japanese baristas. Compared with the common paper filter and dripper combo, the flannel filter is far less popular outside of Japan. Most people’s first encounter with it comes from Japanese coffee culture itself.

That naturally raises the question: why do Japanese people love brewing coffee with a piece of flannel cloth? What makes coffee brewed with flannel so different from coffee filtered through paper?

What’s Special About Flannel Filters?

If you’ve read my posts before, you’ve probably seen me mention this: flannel filters produce coffee that’s richer and more aromatic. The reason is simple — flannel doesn’t filter out oils and insoluble compounds as thoroughly as paper does.

Flannel is a soft, fuzzy fabric that originated in Wales, England. Since its invention, it’s been used in countless applications thanks to its versatility. As a coffee filtration tool, flannel can actually be traced back to the 17th century — before paper filters even existed. At that time, people in Europe used flannel cloth to strain brewed coffee. However, it wasn’t until hand-brewed coffee spread to Japan that flannel filters were truly adopted as a brewing tool rather than just a strainer.

Compared to paper filters, flannel has larger fiber gaps, which allow coffee oils and fine insolubles to pass through. Coffee oils contain fat-soluble aromatic compounds that give the brew a fuller, richer fragrance. Those oils and insolubles also enhance the body, making the coffee feel smoother and more rounded on the palate. That’s the main reason flannel-brewed coffee is so beloved.

Flannel Filter Types and How They’re Used

A flannel filter typically has two sides — one fuzzy (the “nap” side) and one woven (the “cotton” side). The nap feels soft and smooth to the touch, while the cotton side feels slightly coarse due to the weave texture.

Both sides can be used to hold coffee grounds, but most people — myself included — prefer to place the cotton side inside and keep the fuzzy nap side facing outward. Why? Because coffee grounds tend to cling to the nap, making cleaning much more difficult.

Flannel filters are usually attached to a special metal handle. You can hold it in your hand while pouring, or hang it directly over a server like a regular dripper. Most people choose the latter for both the convenience and the ritualistic charm it brings.

How to Brew Great Coffee with a Flannel Filter

Brewing with flannel isn’t much different from using a dripper and paper filter in terms of parameters. However, if you’re hand-holding the flannel rather than placing it on a server, you’ll need to adjust from a coffee-to-water ratio to a coffee-to-liquid ratio, since the scale only measures the liquid dripping out of the cloth.

When using a flannel filter, I prefer deep-roasted beans, as the characteristics of flannel naturally complement darker roasts. For this example, I used a deeply roasted Sumatra PWN Golden Mandheling.

Brewing parameters:

  • Coffee dose: 20g

  • Coffee-to-liquid ratio: 1:13 (equivalent to 1:15 coffee-to-water)

  • Water temperature: 88°C (190°F)

  • Grind size: EK43 at 10.5, with 70–75% passing a 20-mesh sieve (a bit finer than usual hand pour)

  • Pouring method: three-stage pour

Since we can’t see the total water volume when using flannel, the bloom stage is done simply by wetting all the grounds — not by adding double the coffee weight as usual. Start by pouring hot water into the center, then slowly move outward in circles until all grounds are evenly wet. This prevents channeling. Let it bloom for 30 seconds.

After blooming, pour with a steady stream, slowly spiraling from the center outward and back in again, repeating the motion until the water level nearly covers the coffee bed. Wait for it to draw down before starting the next pour.

During the third pour, focus your flow on the center of the bed, keeping your pouring circle within the size of a coin. Once you reach your target yield — in this case 260ml (based on 20g coffee and a 1:13 ratio) — remove the filter and stop pouring. Total brew time: 2 minutes and 21 seconds.

Comparing Flannel and Paper Filter Brews

I also brewed the same coffee using a Kono dripper with paper filter, under the same parameters, to compare. The flannel-brewed cup was noticeably more aromatic, smoother in texture, and had a longer aftertaste — though the differences were subtle unless tasted side by side.

Flavor-wise, both cups expressed the Mandheling’s signature notes of chocolate, nuts, pinewood, and spice, but the paper-filtered version was cleaner, while the flannel version offered a fuller body and deeper richness.

Why Flannel Isn’t Commonly Used in Cafés

You might be wondering — if flannel can produce such wonderful results, why don’t more cafés use it?

The answer is simple: flannel filters aren’t disposable. They require thorough cleaning and sanitizing after each use to maintain quality and hygiene. Compared with paper filters that you can toss out after brewing, flannel takes significantly more effort to maintain.

That’s why even in Japan, many baristas and home brewers now prefer the convenience of paper filters.

Still, both methods have their strengths. Flannel gives you aroma and body; paper gives you clarity and cleanliness. There’s no absolute winner — it all comes down to personal taste and the kind of coffee experience you want.
