Hot, this was pretty good. Not at all sour and also not too similar to other fruit teas. Not sure if the flavor is guava specifically, but it’s light and pleasant, though not super remarkable. Cold, some artificiality came out. I cold-brewed the second steep, and that actually turned out quite pleasant. I drank it as a shower tea – very refreshing! I like having this one in a clear cup because it’s a beautiful color.
