With a simple twist of the knob, you can select just the right temperature of water for different kinds of tea and pour-over coffee. Choose any temperature between 170 and 212°F. The adjustable kettle not only heats water to the chosen temperature, it holds the temperature for up to 30 minutes. No more trips to the kitchen, as this kettle's silicone base lets you place it without fear of ruining table surfaces. Other extras include a slow-opening lid to control the release of steam and a cord that wraps around the base for compact storage.
