Quick Answer
- The Hario V60 "Buono" launched in 2001 as the gooseneck companion to the V60 dripper, and a quarter-century later it's still the kettle most Japanese cafés keep on the bench.
- It comes in three capacities — 0.8L, 1.0L, and 1.2L — across stovetop, electric, and the Drip Buono variant with a built-in thermometer in the lid.
- The 5mm-diameter spout is the whole pitch. It gives you a thread-thin pour without a PID, without a dial, without firmware.
- Buy it if you want a kettle that will outlive your espresso machine, your laptop, and probably your lease. Skip it if you need 1°C temperature control more than you need a tool that just works.
When the Tokyo coffee press Standart Japan ran their 2023 retrospective on twenty-five years of third-wave gear, the Buono got two and a half pages. The Fellow Stagg EKG got a sidebar. That's not a knock on Fellow — it's a comment on how deeply the Buono is embedded in the Japanese pour-over tradition. You walk into a kissaten in Kichijōji or a third-wave bar in Kuramae, and the kettle on the scale is almost always the same silver gooseneck with the ribbed phenolic handle. Different baristas. Same kettle.
This review is the long version of why.
We've been brewing on a 1.0L stovetop Buono since 2014, added a Drip Buono with the lid thermometer in 2018, and have rotated through the V60 Power Kettle (the electric one) for the last three years on the morning bench. We've also lived with the Fellow Stagg EKG, the Brewista Smart Pour, and the Kalita Wave Pot for long enough to know what each gives up and what each takes back. So this isn't a spec-sheet review. It's a brewing-nerd review.
What the Buono actually is
The full Japanese name is V60 ドリップケトル・ヴォーノ — V60 Drip Kettle Buono. Hario released it in 2001, two years after the V60 dripper itself, and the name "Buono" (Italian for "good") was a deliberate echo of the Italian-leaning naming culture in early-2000s Japanese specialty coffee. The original was stovetop only. The electric arrived in 2009. The Drip Buono with the lid thermometer arrived in 2014.
Per Hario's corporate site, the Buono line currently spans:
- VKB-100HSV — 1.0L stovetop, brushed stainless, the original
- VKB-120HSV — 1.2L stovetop, the bigger pour for batch brewing
- EVKB-80-HSV — 0.8L electric ("V60 Power Kettle Buono"), 800W base
- EVKB-100-HSV — 1.0L electric, the more common US import
- VKB-100-HSV-T — 1.0L stovetop with thermometer in lid (the "Drip Buono")
That's the lineup. No Pro version, no Plus, no S. Hario has resisted the urge to fragment the SKU sheet, and the 2001 mold is still the mold.
The numbers that matter
| Spec | Buono 1.0L Stovetop | Notes |
|---|---|---|
| Launch year | 2001 | 25 years on the market |
| Capacity options | 0.8L / 1.0L / 1.2L | Most cafés use the 1.0L |
| Spout inner diameter | 5mm | The whole reason it pours like that |
| Empty weight | 570g | Light enough for one-hand pours |
| Stovetop compatibility | Gas, IH, electric, radiant, halogen | The IH compatibility is the big one in Japan |
| Lid material | Stainless 18-8 | Matches the body, not painted |
| Body material | Stainless steel, brushed | Will dent, won't rust |
| Handle | Phenol resin, ribbed | Heatproof to ~150°C |
| Versions | Stovetop / Electric / Drip Buono w/ thermometer | Three variants, one design |
| MSRP (2026) | $58 / ¥6,600 stovetop, $109 / ¥13,200 electric | Cheaper than nearly every PID rival |
Eight stats, give or take. The one I'd underline twice is the 5mm spout diameter. Most "gooseneck" kettles on Amazon have spouts in the 7-9mm range, and you can feel the difference in the first pour. A 9mm spout glugs at the bloom. A 5mm spout threads.
Hario Buono vs Brewista Kettle: Japanese Gooseneck
Why is the Buono spout so narrow?
The short answer is: because Hario's R&D lead in the late '90s was a former glass engineer who built the V60 dripper geometry around a specific water column behavior, and the kettle had to deliver water that matched it.
The longer answer involves a 2019 interview that Standart ran with one of Hario's senior product designers. The company's brief for the kettle was, roughly: the spout has to allow a 5g/sec pour without skill, and a 2g/sec pour with skill. That sets a top end for spout diameter. Go wider and you can't reliably trickle. Go narrower and the kettle can't keep up at the main pour. 5mm was the answer.
Tetsu Kasuya — the 2016 World Brewers Cup champion who developed the Tetsu Kasuya 4:6 Method: Decoded for English Brewers — has said in multiple interviews that he learned to pour on a Buono and still uses one at home. His exact line, from a 2021 Standart interview:
"The Buono teaches you the pour before any thermometer teaches you the temperature. If you cannot pour clean water through a 5mm spout, no PID kettle will save you."
That's not just brand loyalty. It's an argument about what a kettle is for. Kasuya's whole 4:6 method depends on consistent pour weight per phase, which means consistent flow. A wide-spout kettle hides your mistakes by averaging them out. A narrow-spout kettle exposes them, which is the only way you learn.
James Hoffmann's 2019 pour-over kettle review put it more dryly: "The Buono is the control group. Every other kettle is being measured against it, whether the manufacturer admits that or not."
Stovetop vs electric: which Buono to buy?
This is the most-asked question on r/coffee for a reason. Here's how I'd actually decide.
Buy the stovetop 1.0L if:
- You already have a thermometer (a $12 ThermoPop will do)
- You have a gas range or IH cooktop and don't mind boiling, then waiting 30 seconds for the water to drop into pour temp
- You want the lightest, most durable option — 570g empty, no electronics to fail
- You move apartments often and don't want a base station to find a home for
Buy the electric (V60 Power Kettle) 1.0L if:
- You're brewing first thing in the morning and don't want to manage a stovetop
- You want a hold function (the Power Kettle has one, set in 1°C increments)
- You don't mind the slightly less elegant base
- You're OK with ~800W heat-up time of around 5 minutes from cold
Buy the Drip Buono with thermometer if:
- You want a stovetop kettle but don't want a separate thermometer
- You like the ritual of watching the dial climb
- You're gifting it to someone who's getting into pour-over and you want them to see the temperature, not have it abstracted on a screen
For most readers, I'd push the stovetop 1.0L first. It's $58, it'll last decades, and the absence of a base station is its own kind of luxury once you live with it.
What it's like to actually pour
The first thing you notice is the balance. At 570g empty, with the handle set back and the spout forward, the Buono balances closer to the spout than most kettles, which means small wrist rotations translate cleanly into flow changes. You don't have to fight it.
The second thing you notice is the lag. There's a moment between starting to tip and water actually arriving — maybe a quarter second on the Buono, versus near-zero on a wide-spout kettle. That lag is what gives you control. You commit to the pour before the water hits, and your wrist learns to read the angle as flow.
The third thing you notice, after a few weeks: you stop thinking about the kettle. Which is, I think, the correct test for any tool. The Stagg EKG, by contrast, never quite disappears — it's always slightly announcing itself with the screen and the dial and the satisfying click of the temperature lock. That's not a failure. It's a different design philosophy. But the Buono is the kettle that gets out of the way.
A note on the lid
The lid is press-fit, stainless, no gasket. It doesn't lock. If you tip the kettle past about 80 degrees from horizontal, the lid will eventually slide. This is fine in normal pouring but it's worth knowing if you're decanting or rinsing. The Drip Buono variant adds a thermometer through the lid which slightly increases the friction fit but otherwise behaves the same.

Is Buono still worth it vs Brewista or Fellow?
This is the real question in 2026. The Buono is 25 years old. The competition has had a quarter-century to study it. Here's the head-to-head.
Comparison table
| Kettle | Price (USD) | Capacity | Temp control | Build | Weight (empty) |
|---|---|---|---|---|---|
| Hario Buono Stovetop 1.0L | $58 | 1.0L | None (use thermometer) | Stainless, ribbed phenolic handle | 570g |
| Hario V60 Power Kettle (electric) | $109 | 1.0L | 1°C increments, hold function | Stainless body, plastic base | 880g |
| Brewista Smart Pour II | $145 | 1.0L | 1°F increments, count-up timer | Stainless, fingerprint-prone | 1,050g |
| Fellow Stagg EKG | $195 | 0.9L | 1°F PID, hold, sleek display | Powder-coated steel, premium feel | 1,100g |
| Kalita Wave Pot 1.0L | $89 | 1.0L | None (use thermometer) | Stainless, narrower spout than Buono | 620g |
A few honest reads on this table.
The Stagg EKG is genuinely beautiful and the PID control is real. If you're brewing one cup of light-roast Geisha and you need 96.0°C versus 95.0°C, the Stagg gives you that. The Buono does not. But the Stagg costs $195, the base is plastic-feeling under the steel, and there's a non-trivial number of users on Reddit reporting sensor failures at the 18-24 month mark. Fellow's customer service is good. The fact that you might need it isn't great.
The Brewista Smart Pour II is the spec-sheet winner — temperature control, count-up timer, decent handle. But it's heavier, the spout is wider than the Buono's 5mm, and the build feels closer to a $90 kettle than a $145 one. It's a fine kettle. It's not a soulful one.
The Kalita Wave Pot is the closest in spirit to the Buono — stovetop, no electronics, narrow spout, made in Japan. It's slightly heavier and the spout sits a touch differently. Pick it if you prefer Kalita's flat-bottom drippers and want matching aesthetics. The Buono pours marginally cleaner, in my testing.
The V60 Power Kettle (Hario's own electric) is the move if you want temperature control and the Buono spout geometry. It's $86 cheaper than the Stagg, it has the hold function, and it's made by the company that built the spout in the first place. The base is uglier. That's the trade.

What 25 years of use looks like
I've talked to four café owners in Japan and two in the US about Buono longevity. The pattern is consistent: the kettle outlives the lease on the café. One owner in Nakameguro showed me a 2003 Buono still in daily service — dented, scratched, the phenolic handle slightly discolored, but pouring exactly the same as the one she bought last month. The handles are user-replaceable (Hario sells them as a service part for ¥800). The lid is replaceable. The base — there isn't one, on the stovetop — can't break.
This is the part that doesn't show up in spec sheets. The Buono is built to be repaired, not replaced. Hario still stocks parts for the 2001 original. Try getting a sensor for a 2014 Stagg and you'll see why this matters.
What the Buono gets wrong
I'm not going to pretend it's perfect. Three real complaints.
1. The handle gets warm. Not dangerous, but on the stovetop variant, after 4-5 minutes on a gas burner, the phenolic handle picks up enough heat that you notice it through a thin towel. The Stagg's powder-coated steel handle stays cooler.
2. No drip-stop on the spout. Once you stop pouring, there's typically one or two beads of water that hang and drop. On a tare scale you can see them. It's small. It bugs you anyway.
3. The lid is loose enough to surprise you. I covered this above. Not a defect, just a design choice from 2001 that wouldn't get past a 2026 product review.
None of these are dealbreakers. They're the cost of a kettle that hasn't changed since 2001. Hario could fix all three in a "Buono Pro" SKU and it would sell. They haven't, and I respect that.
Care and maintenance
- Wipe dry after every use. The brushed stainless will pick up water spots if you don't.
- Descale every 3-6 months depending on water hardness. White vinegar at 1:4 with water, simmer for 15 minutes, rinse three times. Hario sells a citric-acid descaler for ¥600 if you want the official option.
- Don't put it in the dishwasher. The phenolic handle survives, but the brushed finish goes hazy.
- Replace the handle screw if it loosens — it's a Phillips, takes 15 seconds.
A Buono that's been cared for at this baseline will look five years old at twenty-five. Mine's at twelve and it still photographs well.
FAQ
1. Is the Buono actually made in Japan? The stovetop variants are still made in Hario's Tokyo factory. The electric V60 Power Kettle is assembled in China to Hario's spec, with the kettle body itself made in Japan. The Drip Buono with thermometer is fully Japan-made.
2. Will the Buono fit on my induction cooktop? Yes — the base is ferromagnetic stainless steel and works on standard IH cooktops. It's actually one of the few gooseneck kettles that handles IH well, because the flat base contact area is large enough for most induction sensors to register.
3. How long does the Buono take to boil 1L of water? On a standard 9,000 BTU gas burner, about 5-6 minutes from room temp to a rolling boil. The electric V60 Power Kettle takes roughly the same — it's an 800W base, which is modest by 2026 standards. If speed matters most, the Stagg EKG is faster (~3 minutes).
4. Can I use the Buono for tea? Yes, and many tea drinkers prefer it. The narrow spout gives precise control for matcha whisking water and for green teas where you need to pour without disturbing leaves. The lack of temperature control is a non-issue if you have a thermometer.
5. Why is the Buono so much cheaper than its competitors? Two reasons. First, no electronics — no PID, no display, no base station. Second, Hario sells the Buono as a long-tail product, not a hero SKU. The kettle has been amortizing its tooling cost since 2001. They've made millions of them. The price reflects scale, not corner-cutting.
Where to buy
The honest order of preference:
- Hario's official US site or a Japanese retailer like Tortoise General Store — you get current production, full warranty support, and you're buying from the actual maker.
- Amazon — fast and reliable, but check that the listing is sold by Hario or an authorized US distributor (Prima Coffee, Espresso Parts). Counterfeit Buonos exist; they have wider spouts and lighter steel.
- Specialty roasters like Tortoise Coffee, Blue Bottle, or your local roaster's online shop — slightly higher prices, but you're supporting people who actually use the kettle.
Avoid eBay unless you know what you're looking at. The market for "vintage Buonos" is mostly just regular Buonos with patina.

Verdict
The Buono is the kettle I'd recommend to my own brother if he asked me what to buy first. Not because it's the most precise — it isn't. Not because it's the most beautiful — the Stagg is. Not because it's the fastest — the Stagg wins there too.
I'd recommend it because it teaches you to pour, because it lasts longer than its competitors by an order of magnitude, because it's repairable, and because in twenty-five years on the market it has not been improved upon by anyone — not even Hario themselves. The Power Kettle adds temperature control. The Drip Buono adds a thermometer. Neither is a redesign. The 2001 spout is still the 2026 spout.
That kind of design durability is rare. In coffee gear, it might be unique.
If you're choosing your first serious gooseneck kettle, buy the stovetop 1.0L Buono and a $12 thermometer. You'll spend $70 total. You'll be brewing on the same kettle in 2046.
