I had this both cold brewed and hot brewed after also trying a sample at the store. The verdict? Hot brewed, it more strawberry than rhubarb, while the cold brew is more on the rhubarb side. I didn’t add sweetener to either but both were enjoyable. At the end of the day, this isn’t a MUST restock, but if i needed something convenient to cold brew over the summer, this is potentially one that i’d get. It’s convenient at least, and tasty. Pretty close approximation to that tangy rhubarb taste that i love….
