Variable Temperature Electric Kettle
Temperature is one of the most overlooked variables in tea brewing, and getting it wrong is the single most common reason people end up with bitter, astringent iced tea. Black teas can handle boiling water at 100°C, but green teas, white teas, and delicate oolongs need cooler water — typically between 60°C and 80°C — to avoid releasing the bitter compounds that make them unpleasant. A variable temperature electric kettle solves this problem completely. You set your target temperature, the kettle heats to exactly that point, and many models will hold that temperature for 30 to 60 minutes so you're not rushing to pour. This is especially valuable when you're making a large batch of iced tea concentrate: you want precise, repeatable results every time. The kettle also heats water significantly faster than a stovetop kettle, which matters when you're making tea regularly. Look for a model with a gooseneck spout for controlled pouring, a keep-warm function, and a capacity of at least 1 litre. Once you start brewing with precise temperatures, you'll never go back to guessing.
