This is sour but refreshing and probably tied with green apple as my favorite of the sour flavors. It's got a nice kick to it but is still sweet. Definitely the most sour of the sours but still an easy drinking level of sweetness. It's a great lunchtime beverage imo. Plus tastes good when you add it to carbonated water or club soda to make a soda out of it. I've bought this flavor multiple times and I'm sure I will again in the future.
