UFO Coffee Dripper Review: The 80° Cone Design That Boosts Sweetness & Clarity

 This UFO-shaped dripper might look like a gimmick at first glance, but its design is anything but superficial. It actually rethinks the fundamental logic of the classic conical dripper—and that genuinely caught my attention. I’m planning to dive deeper into its design principles and extraction benefits before deciding whether to pick one up and share my hands-on experience with you all.

At its core, the UFO dripper still follows a conical structure. However, both its opening angle and overall form differ significantly from most standard cone drippers. The most notable shift? It moves from what we typically think of as a V60 to something closer to a “V80.” Yes—an 80° cone angle. This steeper angle accelerates water flow. On top of that, instead of the usual raised internal ribs, it features recessed ribs. The combination of an 80° cone and concave ribbing works like a double boost: it concentrates water flow, reduces channeling, and ultimately leads to a more even extraction—bringing out brighter acidity and more expressive aromatics in the coffee.

Let’s break it down further.

At first glance, the dripper appears short and wide. If you look closely at the walls, you’ll notice it’s made of thick ceramic—but not with uniform thickness. The upper wall is actually about 23.7% thinner than the lower section. The rim flares outward like a flying saucer, creating a wide lip. This isn’t just aesthetic—it serves a functional purpose. During brewing, heat naturally rises. The space formed between the wide rim and the top of the filter paper allows steam to escape more efficiently, preventing it from accumulating and condensing back into the brew. This helps maintain airflow above the dripper, stabilizing extraction temperature and avoiding overheating in the upper coffee bed—which can otherwise lead to a “steamed” or overcooked taste.

Now, consider this: when the base diameter and dose remain constant, increasing the cone angle spreads the coffee bed wider and reduces its vertical height. This shortens the distance water travels through the grounds, increases the surface area for flow, and lowers resistance per unit area—resulting in a faster overall flow rate. The outcome? A cup that leans toward higher sweetness, lower bitterness, and a cleaner, more refreshing profile.

But there’s a trade-off. A shallower bed combined with faster flow can lead to under-extraction if left unchecked. That’s where the recessed ribs come into play. They prevent water from taking shortcuts along the edges and ensure it passes through the coffee bed. In other words, they act as a forced flow-guidance system, compensating for the reduced contact time caused by the shallower bed.

This type of concave rib design isn’t entirely new—it has appeared in several classic drippers—but compared to the raised spiral ribs of a traditional V60, it offers some distinct advantages. The recessed vertical grooves create a physical buffer zone between the filter paper and the dripper wall. In conventional designs, water can easily slip along the wet filter paper and bypass the coffee bed (a phenomenon known as bypass flow). Here, those grooves “catch” the water and redirect it downward. By blocking edge channels, the design forces water to pass more evenly through the center of the coffee bed, significantly reducing channeling and improving extraction consistency.

This also means the dripper is more forgiving. Even if your pouring technique isn’t perfect—or if your stream hits the edges—the flow system helps guide the water back on track.

As a result, this dripper shows clear advantages when brewing light roasts or coffees with pronounced floral and fruity notes. Think Geisha or Yirgacheffe: you can expect lifted aromatics, lively acidity, and a clean finish with minimal bitterness or woody astringency—even toward the end of the brew.

That said, there’s one important caveat: this dripper is not compatible with standard filter papers. It requires specially designed UFO filters. Interestingly, these filters aren’t made from traditional paper pulp—they’re composed of a food-safe blend of lyocell and PLA. This means you can skip pre-rinsing without worrying about papery off-flavors.

There are two types of filters: Type A and Type F. “F” stands for fast, while “A” stands for average. Compared to A, the F filter is larger. Type A is designed to produce a brighter, more balanced cup, and is generally sufficient for standard use. Type F, on the other hand, enhances body and works well for hybrid immersion-drip brewing methods.

The manufacturer also provides recommended brewing parameters:

For Type F filters (baseline):

• Grind size: 800–1100 μm (Comandante C40: 22–27 clicks)
• Ratio: 15g coffee to 250g water (1:16.67)
  • For more body, increase dose to 16.6g (1:15)
• Water temperature: 92°C ±4°C
  • Dark roast: ~88°C
  • Very light roast: up to 96°C

Pouring structure:

• 00:00–01:00: 50g (circular pour)
• 01:00–01:30: 50g (circular)
• 01:30–02:00: 50g (circular)
• 02:00–02:30: 100g (center pour)

For Type A filters (baseline):

• Grind size: 1000–1300 μm
• Ratio:
  • 13.5g : 225g (lighter, tea-like body)
  • 15g : 225g (juicier mouthfeel)
• Water temperature: 92°C

Pouring structure:

• 00:00–00:30: 45g (circular)
• 00:30–01:00: 45g (circular)
• 01:00–01:30: 45g (circular)
• 01:30–02:00: 45g (center)
• 02:00–03:30: 45g (center)
• Total brew time: under 3.5 minutes

For iced pour-over (Type A):

• Grind size: 1100–1400 μm
• Ratio: 20g coffee : 200g water
• Water temperature: 92°C

Pouring structure:

• 00:00–00:30: 50g (circular)
• 00:30–01:00: 50g (circular)
• 01:00–01:30: 50g (circular)
• 01:30–03:00: 50g (center)

Brew hot, then pour directly over a glass filled with ice and enjoy.

They’ve also released a UFO Dripper V2 made from durable, heat-resistant Tritan, which is better suited for immersion-drip hybrid brewing with Type F filters. I won’t go too deep into that here.

The brand has also collaborated on various limited-edition releases, including filter papers with Spain-based SIBARIST and handmade ceramic drippers with multiple studios. One standout collaboration, in my opinion, is with MK Studio—a Copenhagen-based ceramics studio founded by Magdalena and Michal, a husband-and-wife team. Combining Michal’s background as a chef with Magdalena’s expertise in ceramics, they blend culinary sensibility with artistic craftsmanship. Their take on the UFO dripper is more expressive and artistic, with each color limited to just 60 pieces worldwide—though they’re likely sold out by now.

To wrap it up: from concept to execution, this dripper feels thoughtfully designed and logically consistent. It’s best suited for intermediate to advanced brewers who have some control over their technique. If you’re looking to highlight delicate notes like fruit acidity and florals—and push your pour-over experience to the next level—this might just become your new favorite brewing “toy.”

TINTŌ: An Interchangeable-Base Variable-Flow Dripper Crafted from 99.9% Aerospace-Grade Titanium

 From the title alone, you can already tell that today’s dripper revolves around two core selling points: it’s made from 99.9% titanium, and it features an interchangeable base filter plate. The idea is clear—use material advantages to prevent damage and extend lifespan, while embracing a “one dripper, multiple uses” concept that unlocks more brewing possibilities. When a product’s core features align so precisely with consumer needs, it naturally carries real market value. And yes, that’s exactly what sparked my curiosity to explore it further.

The moment I first saw the TINTŌ dripper, I was reminded of the once-viral Origami dripper. Its early ceramic versions won plenty of fans, but they also came with a painful downside: fragility. One accidental bump could lead to cracks—or worse. Considering that many of these drippers cost hundreds of dollars, breaking one mid-use can feel genuinely frustrating. Perhaps because of cases like these, lighter resin versions were later introduced. Still, whether ceramic or resin, most drippers inevitably show wear over time.

I remember buying a large ceramic cake-style dripper from a certain brand years ago. After some use, fine cracks began to appear in the body. It still functioned, technically—but aesthetically, it was no longer the same.

In many ways, drippers are semi-consumable tools. It’s difficult for them to maintain pristine condition over the long term.

That’s where TINTŌ stands apart. The entire body is crafted from 99.9% aerospace-grade titanium—the same material used in jet engines. Its lifespan surpasses that of most household appliances. The brand even jokes that you could pass it down as a family heirloom. And honestly, from a durability standpoint, even if the upfront price is higher, the long-term cost per use becomes surprisingly reasonable.

Beyond durability, titanium has another critical advantage: it does not react with coffee acids, citrus juices, or any beverage you brew. It is completely inert and biocompatible—which is why it’s used in hip replacements and dental implants.

No metallic taste. No chemical leaching. No allergens.

Just a pure, neutral vessel that preserves the integrity of your coffee’s flavor.

Titanium also offers a well-balanced thermal conductivity. In practical terms, this means the TINTŌ maintains a stable temperature throughout extraction, promoting even saturation and consistent flavor. After preheating with hot water, it retains heat long enough to brew a full pot without significant temperature drop.

Now let’s talk about the second core feature: the interchangeable base filter plate.

The “one dripper, multiple functions” concept isn’t entirely new. One of the most well-known examples is the FLO dripper—originally created by Varia and later refined by Kurasu as a patented design. That system, made of stainless steel, consists of a dripper body and a replaceable bottom filter.

Similarly, TINTŌ offers three interchangeable base plates to suit different brewing needs and scenarios. Each plate provides a distinct flow rate:

• 0.2 mm holes — ideal for extracting bright, fruit-forward Ethiopian coffees

• 0.5 mm holes — well-suited for hand-brewed blends

• 0.8 mm holes — better for darker, espresso-style roasts

The dripper itself consists of three parts: the main body, the base, and the filter plate. Simply rotate counterclockwise to disassemble and clockwise to reassemble. The process is smooth, intuitive, and quick.

Another important detail: because the base and body can be separated, this design avoids a common issue found in traditional drippers—coffee oils accumulating in hard-to-reach seams near the bottom. With TINTŌ, you can keep those areas clean and hygienic, minimizing the potential for bacterial buildup.

They also considered the demand for paperless brewing. By using the 0.2 mm or 0.8 mm base plate alone, you can brew without a paper filter. This allows more coffee oils to remain in the cup, producing a fuller-bodied, richer flavor profile.

If you prefer a cleaner cup using paper filters, TINTŌ is compatible with 185-style filters. The geometry of the dripper has been optimized for the classic circular pour-over technique. Its wide opening and conical walls guide water toward the center for even saturation. Combined with different base plates, you can experiment with a wide range of brewing styles.

Cleaning is equally straightforward. Simply separate the filter plate from the dripper body and rinse each component under running water for about 15 seconds. Use a soft brush if necessary, then dry with a towel or paper towel.

Efficient, durable, versatile—and built to last.

Costa Rica’s “Coffee Sock” Brewer: Strange at First Sight, Surprisingly Comforting

 Step into a small countryside home in Costa Rica and you’ll almost always spot a simple wooden stand hanging on a kitchen wall. In the middle of the stand is a round opening holding a cotton bag with a metal ring, and beneath it sits a coffee cup. This humble setup is the country’s beloved brewing tool: the chorreador — a 200-year-old “old-school treasure” that somehow never went out of style.

The structure is almost shockingly simple. No mechanical parts, no fancy gadgets — just a sturdy wooden frame with a circular hole on top. Fixed inside that hole is a cloth filter called a Bolsita (“little bag” in Spanish). The metal ring snaps perfectly into place, allowing the bag to hang naturally. A cup or small serving pot sits right below it. No assembly needed. You just pick it up and start brewing.

The brewing process is wonderfully soothing. You scoop in some freshly ground coffee, pour hot water slowly into the dry filter, and watch as the water saturates the grounds. Then, drop by drop, the coffee begins seeping through the cloth’s fibers — carrying nutty and fruity aromas — until it drips softly into your cup. No special technique, no stopwatch, no precise choreography. Just a slow, pure moment where everything quiets down and fills with the smell of coffee.

Costa Ricans have been using this simple tool for two centuries. Even with electric coffee makers, pour-over kettles, and gleaming espresso machines everywhere, locals still favor this “old buddy.” It’s inexpensive, easy to use, and preserves the pure, unfiltered essence of the coffee. At this point, the chorreador is more than a brewing device — it’s part of the country’s cultural identity. You’ll see it in nearly every home kitchen and every rustic little café across the countryside. It’s woven into daily life.

The name chorreador comes from the Spanish verb chorrear, meaning “to drip” or “to flow,” which perfectly describes the brewing process as hot water trickles through the grounds. The cloth bag itself has a charming nickname: the “coffee sock.” Much like the “sock tea” used for Hong Kong milk tea, it relies on tightly woven fabric to produce a smooth, clean cup.

Taking care of this “coffee sock” is simple but important. After each use, you just rinse it with clean water — no soap and definitely no detergent. Any leftover scent will ruin the next brew. For deep cleaning, there are unscented soaps made specifically for coffee gear. Over time, the filter naturally darkens from trapped coffee oils. That doesn’t mean it’s dirty — it’s more like a patina, a sign of seasoning. Once a month, scrubbing it gently with salt helps remove oil buildup. Treated well, a single filter can last for several months. It’s both durable and eco-friendly.

So if you ever travel to Costa Rica and want to truly experience the country’s slow-paced, grounded way of life, don’t miss the chance to make a cup using a chorreador. No complex settings, no elaborate steps — just a wooden stand, a cloth filter, and the most honest flavors of coffee. This 200-year tradition of simplicity isn’t just a brewing method. It’s a mindset. In a world that moves too fast, this small moment of slowing down might be the most healing experience of all.

Brew a Great Cup of Coffee with Just 5 Grams of Beans

 Sometimes you might just want a small cup of coffee—maybe for a special blend, or simply to enjoy a few sips without going all in. Every now and then, friends tell me they want to “brew a small cup using just a few grams of beans.”

But if you’ve actually tried it, you’ll probably agree: brewing a good cup with a small dose of coffee is much harder than brewing with a regular amount. Just recently, a friend told me he tried making coffee with only 5 grams of beans, but no matter what he did, it just didn’t taste right. The flavor and body were completely different from what he’d get using a normal dose.

So, why is it so hard to brew coffee with such a small amount of beans? The short answer: the smaller the dose, the more brewing challenges you’ll run into.

Why Small-Dose Brewing Is Tricky

In a previous post, I mentioned that each dripper design has its own “sweet spot” for optimal coffee dose. For example, the Hario V60 01 dripper works best with about 10–20 grams of coffee, while the 02 dripper suits 20–30 grams. That doesn’t mean you can’t brew outside those ranges—it just means you’ll have an easier time getting a great cup when you stay within them.

The main reason is bed thickness. The thickness of your coffee bed affects how much of the coffee grounds the hot water can contact.

• A thicker bed allows the water to pass through more coffee particles, extracting more flavor compounds and improving efficiency.

• A thinner bed limits how much coffee the water touches, leading to weaker extraction.

  

Both extremes—too thick or too thin—make it hard to control extraction. A bed that’s too thick can cause over-extraction; one that’s too thin can cause under-extraction. The “recommended dose range” of each dripper basically ensures you’re building a coffee bed with just the right thickness. Step too far outside that range, and things get more complicated.

---

Water Volume Matters Too

Besides bed thickness, the amount of water plays a huge role in how difficult the brew becomes. Less coffee means less water, and less water means shorter contact time.

If you pour the same way you usually do, the brew will finish too quickly—before proper extraction can happen. That’s why people often find small-dosage brews taste weak: there simply isn’t enough time for the water to pull out all those flavorful compounds. Combine that with the thin coffee bed issue, and you’ve got the perfect storm for a disappointing cup.

---

But Hard Doesn’t Mean Impossible

The good news? You can brew a tasty cup with as little as 5 grams of coffee—if you tweak your brewing parameters. With the right adjustments, you can achieve the same flavor intensity and extraction as a full 15-gram brew (well… a smaller cup, of course).

There are five main factors that determine your extraction efficiency:
water temperature, grind size, time, ratio, and pour rate.

If one of them falls short, you can balance it by adjusting another. For example:

Let’s say you normally brew at 92°C with a fine-sugar grind, and the flavor comes out balanced. Imagine each of these factors—temperature and grind—contributes an “extraction strength” of 5, for a total of 10. That’s your ideal brew strength.

Now, suppose you accidentally grind coarser, like raw sugar, reducing grind efficiency to 3. To compensate, you could raise your brew temperature to 94°C or 96°C, bumping the water’s extraction strength up to 7. Add them together (3 + 7 = 10), and you’re back to a balanced cup.

Of course, real-life brewing isn’t that mathematical, but the principle holds true.

My 5-Gram Brewing Guide

If you often make small-batch coffee, I recommend getting a V30 dripper. Its steeper angle allows you to form a thicker coffee bed with the same small amount of grounds, helping the water extract more evenly and adding complexity to your cup.

But since most people only have a V60 or similar dripper, that’s what I’ll use for today’s example.

Coffee used: Ethiopia “Flower Queen”
Dose: 5g
Brew ratio: 1:15
Water temperature: 92°C
Grind size: 85% pass rate through a 20-mesh sieve (for 15g brews, I normally use 75%)
Dripper: Hario V60

As you can see, I only adjusted the grind size—everything else stayed the same as my 15g recipe. Why? Because I use a multi-stage pour to stretch the total brew time to about 2 minutes. This prevents the brew from finishing too quickly due to the smaller water volume.

Since each pour contains less water and causes less agitation, I compensate by grinding finer to maintain extraction efficiency.

---

Step-by-Step

1. Bloom: Start by pouring 10ml of water (2x the coffee dose) to wet the grounds. Let it bloom for 30 seconds.
   Because the water volume is so small, pour gently—slowly, slowly, slowly.

   

2. Main pours: Pour the remaining 65ml of hot water in 3–4 small stages. Each time, stop when the water level is about to submerge the grounds completely. Wait for it to drain before the next pour.

   

3. Finish: Once all the water has passed through, remove the dripper and you’re done.

   

The total brew time should be around 2 minutes and 5 seconds—about the same as your regular 15g brew.

---

The Result

This cup, brewed with just 5 grams of beans, turned out beautifully balanced and full of character. The Flower Queen’s notes of strawberry, citrus, cream, and oolong tea all came through clearly, with no bitterness or off-flavors.

To double-check, I measured it with a refractometer:

• TDS (strength): 1.59%

• Extraction yield: 21.90%

Perfect numbers.

So, as long as you use the right parameters and pouring technique, even 5 grams of coffee can yield a cup that’s every bit as delicious as a standard brew.

I’ve shared similar methods for 6g and 7g brews before—the approach is the same, and it’s surprisingly simple. Give it a try and see for yourself!
