Good cold brew concentrate, nice flavor and very convenient. It took a few tries to get it to taste the way I like it, I found I needed a lot of sweetener because it is quite strong! This is saving me from my Dunkin run every morning and although it's a bit pricey, the 2 pack has lasted about six weeks for me. The number of servings feels a bit misleading, since it is 21 six-ounce servings, but the instructions on how to prepare it are for an eight-ounce serving which would only be 16. Either way, I'm happy with how long they've lasted and it really is good coffee!
