★★★★★
“Crisp Apple tastes much fresher than I expected. It’s more like a cold green-apple drink than a sour sweet, and over ice it’s probably the most refreshing flavour.”
Olivia D. Taste
★★★★★
“I like having these in my work bag because there’s nothing bulky to carry around. Crisp Apple with really cold water has become my go-to on busy afternoons.”
Zoe F. Convenience
★★★★★
“Crisp Apple is the one that made me stop buying cans as often. I like that I can keep the sachets anywhere and make a cold drink when I actually want one.”
Lucy A. Switch from cans
★★★★★
“I ordered Crisp Apple thinking it would just be the safe option and ended up liking it the most. Clean, fresh and not overly sweet — it’s the first flavour I add now.”
