How to Choose an Electric Kettle: 4 Questions That Find the Right One

A digital temperature display (showing current water temperature) is more useful than a built-in thermometer because it is integrated into the keep-warm control, set the target temperature and the kettle maintains it, no reading required. A dial thermometer in the spout or body requires you to read it separately from the kettle controls. For green tea: the kettle either holds the temperature you set (variable digital kettle) or you estimate by feel (no thermometer) or read a separate dial. The digital display on variable temperature kettles is the most practical solution, it combines temperature setting and feedback in one display.

Glass (borosilicate) and stainless steel are equally taste-neutral. Glass allows you to see the water level from the outside and watch the boiling process, some people find this visually satisfying. Stainless steel is more impact-resistant, better insulating, and more durable under daily use. For practical household use: stainless steel. For the visual experience or countertop display preference: glass is fine. Avoid plastic interior kettles for beverage use; they are adequate for cooking but can affect taste in the first weeks of use.

Presets matter for tea drinkers because specific tea varieties have specific ideal temperatures, green tea at 175°F, oolong at 190°F, black tea at 212°F. A kettle with 6 presets covering these ranges removes the need to set a custom temperature each use. Presets do not matter for pour-over coffee, where the optimal temperature is a specific number (usually 200°F to 205°F for most roasts) that you set once and use consistently, a preset at 200°F does the same job as a continuous dial set to 200°F. For dedicated pour-over coffee: continuous variable is slightly more flexible. For tea drinkers with multiple tea types: a preset kettle with labeled temperature settings removes friction.
