Cold is the way to go. Icing it allows the fruitiness of the tea to come through in a more pronounced fashion. I personally had a hard time distinguishing this as “guava” though my dad tried it and thought the flavor was there. There’s a bit of tartness from the apple and hibiscus but it’s a true hint; generally this is a very refreshing fruit tea that is neither sweet nor tart. I don’t know that I’d buy more any time soon (I still have to try all their other teas, for one thing), but I wouldn’t object to having a cup of this.
