Is the mocha cold brew supposed to taste extremely sour?
Trying to figure out whether I've been poisoned by a nefarious Costco court adviser or something. I got a mocha cold brew for the first time yesterday, and it tasted incredibly sour and kind of fruity (barely like coffee at all) with the chocolate as an undertone. My working theory is that the smoothie next to it in the machine somehow impacted the taste. Is this the price of getting what is effectively a milkshake/slushie for $2.99, or is it supposed to taste different?
