Thanks to their transparent design, glass electric kettles make it easy to know how much water is left and are fun to watch as your water moves into a rolling boil. With so many options available, choosing the best glass electric kettle mainly comes down to features and, of course, your budget. Here are a few other things to keep in mind as you shop.
First, since we’re talking about glass kettles, it’s important to pick an option that’s durable. Look for models made from borosilicate, a sturdy glass that won’t shatter if you accidentally clank your mug against it or bump it on a faucet.
Most electric kettles have a simple on-off switch, but some have features like giving you the ability to adjust the water temperature so whether you're making delicate green tea, pour-over coffee, or instant soup, you’ll be able to dial-in on the precise temperature for perfect extraction and flavor. And, for anyone looking to brew multiple cups of tea or hot water, look for a kettle with a keep warm feature so you don't have to reboil the water when you want a second cup.
Kettles generally range between 1 and 2 liters of capacity, so decide how much volume you need. The bigger the kettle, the less often you’ll have to fill it.But, keep in mind, it takes longer to boil large quantities.
