Best variable temperature kettles to control your boil

Tea-drinking is practically a national obsession. There are few occasions or catastrophes that aren’t celebrated or untangled before sitting down with a steaming hot brew.

Yet the first step to a perfect cuppa isn’t simply sticking the kettle on. While both undoubtedly require hot water to release their flavours, various teas and coffees taste better in different temperatures. No need to stand by the counter with a thermometer in hand; variable temperature kettles are here to do the work for you.

The hot water makers allow you to set the temperature to the precisely the right degree for your next cup of whatever you fancy, taking guesswork out of the equation.

What is the right temperature for tea?

According to the Rare Tea Company, 70°C is the right temperature for white and green tea as well as chamomile, while black and oolong do best in water heated to 85°C. Fancy a herbal infusion? It’ll taste best in 100°C water.

What is the right water temperature for coffee?

Coffee is a similar story, according to Colombia Coffee Roasters, with water around  90.5 - 96.1°C to extract the flavour while maintaining the quality.

Hot drinks aside, you may want different temperatures to help prep cooking ingredients for your next meal, and variable temperature kettles can help with that too. Whether you’re parboiling potatoes or want to give your rigatoni a head-start, you’ll thank your kettle’s temperature control feature.

Can a variable temperature kettle lower my electricity bills?

Yes, variable temperature kettles are energy efficient. With household bills on everyone’s mind, a variable temperature kettle can help cut your energy usage. Every option on our list has a ‘keep warm’ feature, which means less need to reboil - for up to 40 minutes in some cases. This means you can make a cuppa when you fancy it and anyone else in your household can use the same heated water without switching the unit on again. Small changes can add up to big savings.

We’ve rounded up the best models to spend your money on right now.
