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.
