The flavor is just plain, minerally oolong. I don’t taste any lime or cucumber…maybe cucumber skin if I’m really trying to picture it? I’m not an oolong fan, so this isn’t really for me, unfortunately. Cold, it’s fine, but there’s a hint of bitterness since I didn’t know how long to steep this for and the website didn’t say – I guessed three minutes, which may not have been right. This has such a vegetal flavor that I wouldn’t have tried it if not for the advent calendar.
