I prepared this tisane as directed by infusing a tea bag in hot water. The beverage turned out too sour for me. Then I decided to prepare another one by infusing a tea bag in room temperature water, left it in the chiller overnight and voilà, it turned out very refreshing, extremely suitable to be drank on warm afternoons. The beverage tastes pleasantly sweet, with a hint of sourness, and has a smooth mouthfeel. It's worth the buy.
