Fellow Stagg EKG Kettle Review (2026): Still the One?
TL;DR: The Fellow Stagg EKG remains the best pour-over kettle for most home brewers. Its 0.1°C PID accuracy, gooseneck precision, and hold function set a standard no competitor has convincingly beaten. The 2026 model adds a slightly faster boil time and improved app stability — but if you already own one, there’s no reason to upgrade.
What Is the Fellow Stagg EKG?
The Stagg EKG is a variable-temperature gooseneck electric kettle with PID temperature control, a 60-minute hold function, and optional Bluetooth app connectivity. It’s designed for pour-over, AeroPress, and any brew method where water temperature and pour control directly affect extraction.

Fellow released the original Stagg EKG in 2018. Since then, the core formula hasn’t changed much — and that’s the point. The 2026 version refines an already mature product: the heating element is slightly more powerful (1200W vs. 1000W on older units), the LCD display is brighter, and the Bluetooth pairing on the EKG+ variant is now faster and more stable than the notoriously finicky early firmware.
Available in two versions:
- Stagg EKG — standalone kettle, no Bluetooth
- Stagg EKG+ — adds Bluetooth and Fellow’s Atmos app integration

Pour Control and Gooseneck Design
The Stagg EKG’s gooseneck spout is the benchmark other kettles are measured against. The counterbalanced handle and weighted base keep the kettle level mid-pour, so flow rate stays consistent without deliberate wrist adjustment. For a Hario V60 or Chemex bloom, that control is the difference between a flat extraction and a channeled one.

The spout opening is narrow enough that you can hold a 3g/s flow without fighting the kettle — something cheaper goosenecks make harder than it should be. At 0.9L the capacity is right for a single 20–25g dose brew, but anyone making two consecutive coffees will need to refill.
Heating Speed
At 1200W, boiling 0.9L from room temp takes about 3.5 minutes — roughly 30 seconds faster than the original 1000W version. That’s not a selling point on its own, but it removes the minor annoyance of the older unit lagging behind your grinder.
Temperature Accuracy and Hold Function
PID control here means the kettle actively regulates power to maintain your target temperature, not just cut power when it hits the setpoint. In practice: set 93°C for a light roast pour-over, and the kettle holds within 0.5°F for the full 60-minute hold window. That’s genuinely useful for multi-cup service.

The hold function alone justifies the price premium over non-PID goosenecks like the Bonavita 1L. With a Bonavita, you’re racing the temperature drop from boil. With the Stagg EKG, you dial in once and brew at your pace.
Dialing by use case:
- Light roast pour-over (V60, Chemex): 93–96°C
- Medium roast drip / AeroPress: 88–92°C
- Cold brew concentrate top-up: 100°C
- Green tea / delicate oolongs: 70–75°C
EKG+ Bluetooth and App
The EKG+ Bluetooth adds remote temp setting, brew presets, and temperature curves via Fellow’s Atmos app. Honest assessment: it’s a nice-to-have, not a must-have. The main value is saving named profiles — your light roast V60 preset loads in two taps instead of dialing the knob each time.

The 2026 app firmware fixed the most-complained-about issue from 2024: BLE connection drops mid-hold. It now reconnects automatically if you walk out of range and back. Still, if you’re choosing between EKG and EKG+ purely on the app: the $20 premium is only worth it if you rotate between 3+ temperature profiles regularly.
Knob Feel and UI
The rotary encoder on the 2026 unit has slightly more resistance than previous versions — less likely to accidentally change temp when picking up the kettle. Small change, noticeable improvement.
Fellow Stagg EKG vs. Competitors
| Kettle | Price | Wattage | PID | Hold | Bluetooth | Gooseneck Quality |
|---|---|---|---|---|---|---|
| Fellow Stagg EKG | ~$79 | 1200W | Yes | 60 min | No | Excellent |
| Fellow Stagg EKG+ | ~$99 | 1200W | Yes | 60 min | Yes | Excellent |
| Brewista Artisan 600mL | ~$75 | 600W | Yes | 60 min | No | Very Good |
| Hario V60 Power Kettle | ~$65 | 800W | Yes | 60 min | No | Good |
| Bonavita 1.0L Variable | ~$50 | 1000W | No | No | No | Decent |
| Timemore Fish Smart | ~$89 | 1200W | Yes | 60 min | Yes | Very Good |
The Timemore Fish Smart is the closest real challenger. Its BLE implementation is arguably more stable than the early EKG+ firmware was, and the pour feel is excellent. But the Stagg EKG still wins on gooseneck balance and the weight distribution that makes sustained pours effortless.
The Brewista Artisan is worth knowing about for smaller batch brewers — at 600mL it’s lighter and easier to control for a 15g dose. The tradeoff is capacity for service situations.
Who Should Buy the Stagg EKG
- Pour-over purist: Buy it. The gooseneck and PID combination is the whole point.
- AeroPress daily driver: Yes — temperature repeatability improves shot-to-shot consistency more than most people expect.
- French press / immersion brewer: The EKG works fine, but the gooseneck adds no value. A cheaper variable kettle like the Bonavita serves you equally well.
- Tea specialist brewing multiple styles daily: The EKG+ with named presets makes sense. Otherwise, the base EKG and manual dialing is fine.
- Existing EKG owner (pre-2024): Skip the 2026 upgrade. The faster boil and better app aren’t worth the cost unless your unit has hardware issues.

FAQ
Is the Fellow Stagg EKG worth it for beginners? Yes, with one caveat: if you’re brewing with a basic drip machine and aren’t controlling brew variables yet, a $79 kettle is premature. Once you’re using a pour-over or AeroPress and paying attention to dose and grind, the temperature consistency pays dividends immediately.
What’s the difference between the Stagg EKG and EKG+? The EKG+ adds Bluetooth connectivity to Fellow’s Atmos app, which lets you set and save temperature profiles remotely. The heating element, gooseneck, PID system, and hold function are identical between both versions. The $20 premium is for the app integration only.
Does the Fellow Stagg EKG work for tea? Yes. The temperature range starts at 135°F (57°C), which covers green tea, white tea, and delicate oolongs. The 60-minute hold is genuinely useful for repeated cups from the same kettle. It’s a capable tea kettle that happens to excel at coffee.
How long does the Fellow Stagg EKG hold temperature? The hold function maintains your set temperature for up to 60 minutes, then shuts off automatically. Fellow specifies temperature stability within ±1°F during the hold window on the 2026 unit — consistent enough that the first cup and the fourth cup brew at effectively the same temperature.
Can the Fellow Stagg EKG be repaired if it breaks? Fellow offers a 2-year warranty and has historically honored it for heating element failures. Replacement bases are available separately, which is useful since the 360° base is the most common point of failure on heavily used units. The kettle body itself rarely fails.
