This is a three-ingredient drink that costs under $2 per serving if you buy cold brew concentrate at Walmart or ALDI and coconut water at any Charlotte chain—no special trips needed. The 45-minute stated time is dishonest: you're pouring three things into a glass, which takes two minutes; the confusion likely comes from brewing time if you're making cold brew from scratch, but concentrate sidesteps that entirely. The real advantage is that it's a same-day drink that hits fast on a warm afternoon, requires zero technique, and coconut water and cold brew are both shelf-stable staples worth keeping on hand. The only caveat is that this works best as a single-serving refresher rather than meal-prep or a dish to stretch across a family.
