I was super excited to try this flavor and it did not disappoint! It's not "sour", exactly, but I think it would probably be strange if it was, lol. But it does taste just like you're enjoying sour watermelon gummies! It's so much fun while still functioning as a way to make me functional. ;)
As with all Fuelers, there is significantly less sugar per serving vs. the cold brew coffees and are brightly colored, have a great non-coffee taste, and all while holding as much caffeine as a cold brew.
