Stagg EKG Matte White Kettle
The Stagg EKG is a 900 mL variable temperature kettle that ticks all the right boxes: it looks great, it's fast and accurate, it couldn't be easier to use, and it is a joy to brew with. A powerful 1200 W heating element combined with a smart PID controller means in no time at all you've have precisely heated water at exactly the temperature you wanted. Using the EKG is simple and intuitive: just twist the knob to set your desired temperature, flick a switch for F or C, click the button built into the knob to turn the kettle on or off. A bright LCD display shows your current kettle temp and setpoint, plus features a brew stopwatch timer you can use while pouring. The optional Hold function will keep the kettle at your desired set temperature for up to an hour before going into standby mode. After 15 minutes of standby time, the kettle will automatically shut off.
Like the stovetop Stagg kettle, the EKG features a precision pouring spout and a counter-weighted handle for better pour control. The flow rate from the spout is perfectly good for pour over brewing, but we found it to be slow compared to the Bonavita variable temp kettle, so it may not be ideal for immersion brews or cupping. The kettle and lid are made of 304 stainless steel, and the base and handles are made of plastic. Kettle and base are not dishwasher safe.
The EKG+ model includes built-in Bluetooth to connect to a mobile app, currently available from either Fellow or Acaia. Through the app, you can turn the kettle on and off remotely, set a temperature and hold it for up to an hour, or log your whole brew (Acaia-only). As of May 2018, only iOS devices can connect to the Stagg EKG+, but Android apps are said to be on the way. To set the kettle into Bluetooth mode, first make sure the base unit is plugged in and powered on. Remove the kettle, then hold down the dial button for three seconds. The words "Bluetooth Enabled" or "Bluetooth Disabled" will appear on-screen. Turn the dial left or right to select the desired option, and click the button once to save the setting. Enable the Bluetooth on your mobile device, and you're all set to connect with the app of your choice!
