You wouldn’t bake a cake at 500°F. So why would you steep green tea in water heated to a rolling boil? The utiliTEA kettle is a variable temperature kettle powered by a 1500 watt heating element and designed for tea drinkers who know that all hot water is not created equal. Turn the dial on the side to the red section on the right to boil water for black tea, or turn it up to the green section to heat water to 30 degrees below boiling – the perfect temperature for green tea. In less than 5 minutes, the kettle reaches your preferred temperature.
