This is a very good blueberry green, but the water temp and timing have to be exact. If the water is too hot or the leaves are allowed to steep for longer than 90 seconds the tea becomes horribly bitter. Brewed properly this is a wonderful tea. Lots of blueberry with a great green tea base. I like how the vegetal flavor of the green tea pairs with the blueberry flavor. I tried it with and without sugar, and I prefer it without because the tea is wonderfully balanced on its own.
