Tap or bottled? Water impacts health benefits Green tea

In tests conducted at Cornell’s Sensory Evaluation Center, consumers liked green tea brewed using tap water more than using bottled water, because it produced a sweeter taste. “But, when steeped in bottled water, the green tea contained about double the amount of the antioxidant epigallocatechin gallate (EGCG) – which makes it more bitter than tea brewed with tap water,” said Robin Dando, Cornell associate professor of food science.
