Discovering calpis was one of the best things that happened to me on my trip to japan! It's hard to describe the taste of it, it's sweet and slightly acidic, a bit like a less intense version of yakult. The melon version of this drink didn't taste very much like melon and more like chemical sweetness but in a weirdly intriguing way. The fact that it was carbonated was also a big plus, since almost every beverage tastes better with carbonation. All in all, I enjoyed this drink very much though I would probably rather go for the strawberry flavoured version if given the choice. 7/10.
