Most people choose a kettle like they’re picking a random sparring partner. They grab the shiniest one, fill it up, and wonder why their brew tastes like a lukewarm jab. Today, we’re putting two gooseneck kettles in the ring to see which one throws the perfect punch.
In the red corner: the Fellow Stagg EKG, the electric darling of the pour-over world, with its sleek design and precision temperature control. In the blue corner: the Hario V60 Buono, the timeless stalwart, a simple stainless steel workhorse that’s been knocking out quality brews for decades. Only one can wear the belt. Let’s score this fight.
The Stagg EKG struts into the arena with a matte black finish, a weighty feel, and a LCD screen that glows like a championship belt. It’s got that premium, “I mean business” vibe. The Buono, meanwhile, shows up in a no-frills box, polished steel gleaming like a veteran’s championship ring. It’s lighter, simpler, and doesn’t need a plug to fight.
Unboxing the EKG reveals the kettle, a sturdy base, and a power cord that feels like it could tow a truck. The Buono? Just the kettle and a sense of nostalgia. No cords, no screens, just pure steel and intention.
But first impressions aren’t just about looks—they’re about feel. The EKG’s handle is ergonomically curved, resting naturally in your grip like a well-worn glove. The Buono’s handle is a simple loop of steel, functional but lacking the EKG’s refined contour. When you lift them empty, the EKG feels substantive, a tool built for daily labor. The Buono feels light, almost eager to dance.

In the Ring (Testing): Performance & Pour
We tested both kettles with the same pour-over setup: V60, 20g of coffee, 300g water, aiming for a 2:30 draw time. We used the same grind size, same water source, and same barista (me) to eliminate variables.
Fellow Stagg EKG: Set to 205°F, the EKG heated up in under 4 minutes. The temperature held steady throughout the pour, fluctuating no more than 1°F. The flow control stalk allowed for a slow, steady bloom (we used a 45-second bloom at 2ml/sec) and a faster drawdown. The pour was smooth, with minimal agitation. The draw time hit 2:28, and the cup tasted clean, sweet, with bright acidity and a lingering floral note.
Hario V60 Buono: Heated on a gas stove to ~205°F (measured with a thermometer), the Buono reached temp in about 3 minutes on medium heat. Maintaining that exact temperature required constant attention—too high a flame and the water crept past 210°F, too low and it dropped below 200°F. The pour required more wrist control—the spout is narrower, demanding a deliberate tilt to avoid a flood or a trickle. We managed a consistent pour after a few practice runs. The draw time was 2:32, and the cup was equally clean, with a slightly heavier body and a hint of roasted sweetness.
Both kettles performed admirably. The EKG won on consistency and ease of use. The Buono won on simplicity and portability. But let’s break down the numbers further.
Temperature Stability: The EKG’s PID control kept water within ±1°F of setpoint. The Buono varied by ±5°F over the course of a pour, requiring active management.
Pour Precision: The EKG’s flow control stalk allowed us to adjust flow rate from a slow 1.5ml/sec bloom to a vigorous 8ml/sec drawdown. The Buono’s fixed spout meant we relied solely on wrist angle to control flow, which introduced variability.
Speed: The EKG heated water faster (3:45) than the Buono on a standard home stove (4:10), though the Buono would be faster on a high-output burner.
How to Use: Step-by-Step Setup
Fellow Stagg EKG:
- Place the kettle on its base and plug it in.
- Use the dial to set your desired temperature (we recommend 200-205°F for pour-over, 208°F for French press).
- Wait for the heating indicator to stop blinking—temp is locked.
- Lift the kettle, pour through the flow control stalk, adjusting tilt for flow rate. The stalk’s angle directly controls flow: more vertical = slower flow.
- After use, return to base to maintain temperature (if desired) or switch off to save energy.
- Descale monthly if you have hard water—use a 50/50 vinegar-water solution, fill, soak for 30 minutes, then rinse thoroughly.
Hario V60 Buono:
- Fill the kettle with water (max 0.8L for optimal pouring—overfilling risks spillage).
- Place on stove over medium heat (gas or electric coil works best; induction requires a steel interface disk).
- Monitor temperature with a thermometer (we recommend a clip-on probe for continuous reading).
- Once at temp, lift and pour, using wrist tilt to control flow. Practice pouring water into a measuring cup to develop muscle memory.
- Remove from heat immediately after pouring to prevent overheating and potential damage to the kettle’s finish.
- After each use, rinse with warm water and dry with a soft cloth to prevent water spots. Descale quarterly with citric acid solution.
The Good: 3-5 Strengths
Fellow Stagg EKG:
- Precision temperature control: Set it and forget it—no guesswork, no thermometer needed. Critical for light roasts where 5°F can change the cup profile.
- Hold function: Keeps water hot for multiple brews—perfect for households with multiple coffee drinkers or cafe settings.
- Flow control stalk: Adjustable pour rate for different techniques—slow bloom for immersion-style pours, fast drawdown for high-agitation methods.
- Build quality: Feels industrial-strength, ready for daily abuse. The base is die-cast metal, the kettle is food-grade 304 stainless steel.
- Style: Looks like it belongs on a pro barista’s counter. The minimalist design doesn’t scream “appliance”—it whispers “precision tool.”
- Additional features: LCD screen shows real-time temp and hold time, Brew Stopwatch activates when lifting the kettle, and the optional Fellow app lets you save presets.
Hario V60 Buono:
- Simplicity: No electronics, no failure points—just steel and fire. Drop it, kick it, it’ll still work.
- Portability: Use it on a camp stove, a hotel hot plate, or your home burner. No plug needed.
- Price: Less than a third of the EKG’s cost. You could buy three Buonos for the price of one EKG.
- Lifetime warranty: Buy it once, use it forever. Hario stands behind this kettle for decades.
- Pour control: Master the tilt, and you can replicate any electric kettle’s flow. Many baristas prefer the Buono for its tactile feedback.
- No scale buildup concerns: Stainless steel interior is easy to clean and descale.
- Silent operation: No hum, no click, no electronic noise—just the quiet whistle of steam (if you let it whistle, which we don’t recommend for precision brewing).
The Bad: 2-3 Weaknesses
Fellow Stagg EKG:
- Price: $150 is a steep investment for a kettle—equivalent to a specialty coffee subscription for three months.
- Dependence on electricity: No power, no hot water. useless during outages or off-grid adventures.
- Learning curve: The flow control stalk takes practice to use intuitively. New users often pour too fast or too slow initially.
- Potential failure points: More parts mean more things that can break—screen, dial, heating element, sensor.
- Aesthetic limitation: Only available in matte black or polished steel—no color options to match your kitchen.
Hario V60 Buono:
- No temperature control: You need a separate thermometer for precision, adding cost and clutter.
- Manual heating: Requires attention to avoid overheating (which can damage the kettle’s welds) or underheating (which yields sour, under-extracted coffee).
- Pour technique: The narrow spout demands skill to avoid channeling or stalling. Beginners often struggle with inconsistent flow.
- Heat retention: Once removed from the stove, water cools faster than in the EKG’s double-wall cavity (though the EKG isn’t advertised as double-wall, it does retain heat better due to mass).
- Handle heat: The handle can get warm during prolonged use—use a kettle mitt or towel if heating large volumes.
