02 — The Story
The Fellow Stagg EKG Pro is the kettle that made variable temperature control look like it belonged in a residential kitchen. 0.9 liter capacity, 1200 watts, temperature hold at any degree between 40°C and 100°C for 60 minutes. The gooseneck spout produces a 9mm stream at typical pour angles — narrow enough for precision, wide enough that you're not nursing a single cup for three minutes.
The Pro version adds Bluetooth connectivity and a custom brew timer accessible through the Fellow app. Set target temperatures for different coffees, create presets for your morning Kenyan and afternoon Brazilian, track pour times without a separate device on the counter. The base updates firmware over-the-air, which matters when a company keeps refining PID algorithms. The 304 stainless steel interior is food-grade and BPA-free; the matte exterior stays cooler to accidental touch than polished finishes.
We use the Stagg EKG Pro for all our manual brews at the Rome location. Gesha at 91°C, naturals at 94°C, washed centrals at 93°C — the half-degree precision matters when you're trying to coax clarity from a $40 bag. The built-in timer starts automatically when you lift the kettle, which sounds minor until you realize you've been fumbling with your phone between pours for years. The counterbalanced handle keeps the pour steady at full weight; the tilted base shows temperature and timer at a readable angle.
This is for the home brewer who has already dialed in grind size and discovered that water temperature is the next variable worth controlling. If you're brewing the same medium roast at 96°C every morning and it tastes fine, a variable kettle won't revolutionize your life. If you've started buying microlots, experimenting with lower temperatures for naturals, or noticed that your Ethiopian tastes astringent at the same temp that makes your Colombian shine — this becomes the tool that lets you test hypotheses instead of guessing. The Stagg EKG Pro costs more than a basic variable kettle and less than replacing three bags of coffee you brewed incorrectly.
04 — FAQ
Questions, answered.
What's the difference between the standard EKG and the Pro?+
The Pro adds Bluetooth connectivity, app-based presets, brewing guides through the Fellow app, and a built-in brew timer that starts automatically when you lift the kettle. The standard EKG requires manual temperature setting via the dial each time. Both maintain temperature for 60 minutes and have identical pour control.
How precise is the temperature control, and does half a degree matter?+
The PID controller maintains temperature within ±1°C. Half-degree precision matters most with light roasts and high-grown coffees where a 2-3 degree shift affects extraction noticeably. For medium and dark roasts, one-degree increments are sufficient. The precision is more useful than the accuracy for repeatability.
Can I use this on an induction cooktop, or is it electric only?+
Electric heating base only — this isn't stovetop compatible. The 1200-watt element brings 0.9 liters to boil in roughly four minutes from room temperature. The plug is EU standard; the base stays stationary while the kettle lifts off for pouring.
Is the app required, or does the kettle work without it?+
The kettle operates fully without the app. Use the physical dial and buttons on the base to set temperature, start hold mode, and view the timer. The app adds convenience for saving presets, accessing brewing guides, and firmware updates, but nothing is locked behind the software.
What's the actual pour rate from the gooseneck at normal angle?+
Approximately 9mm stream diameter produces 30-40 grams per ten seconds at a 45-degree pour angle with moderate speed. Fast enough for a V60 or Kalita without stalling, controlled enough for slow Chemex pours. The spout design prevents drips when you stop mid-pour.
