Winner of the prestigious Red Dot design award in Europe, Tea Control is a brewing teapot that enables you to enjoy tea at any strength you like, from the first cup to the last. Simply add tea leaves to the filter and pour hot water over them to fill the pot, letting the tea brew. When the tea is at the desired strength, turn the lid clockwise to control the brewing. Made from clear, heat-resistant borosilicate glass, it is ideal for loose leaf tea and even tea bags. Its filter is made out of BPA-free Tritan copolyester with a patented brew control mechanism that doesn't need be removed, allowing you to brew and serve anywhere. Dishwasher safe.
