January is National Hot Tea Month and according to Cindi Bigelow, CEO of Bigelow Tea in Fairfield, CT, brewing the best mug requires only a few simple steps. First, Bigelow says to start with clean water. “The vehicle in which you’re going to boil water, as well as the mug itself, should also be clean,” says Bigelow. The water should also be the right temperature: for black and herbal tea, go for a true boil; for green tea, the water should just begin to boil. Finally, black and herbal teas should be brewed for a minimum of four minutes, while green tea should be brewed from two to three.
