The Best Store-Bought Cold Brew, Blind Tested

Sample review with illustrative data — replace with your real test results before publishing.
Grocery cold brew has quietly become a real category with a real quality spread — the gap between the best and worst bottle in the cooler is wider than most cafés' entire menu. So we did what this site exists to do: bought everything with our own money, hid the labels, and scored each product out of 100.
How we tested
Every product was purchased at retail, chilled to 38°F, and poured by a second person into identical glasses so the taster never saw a label. Everything was tasted black first — milk hides sins, and we want to know about the sins. Concentrates were cut exactly to their label directions before scoring. We recorded price paid and computed price per ounce for the value score, re-tasted every product the next day to check consistency, and scored on the eight-criteria, 100-point scale described in full in our methodology.
Three products anchor this first board. The leaderboard grows with every test — see "what's next" below.
What to buy
- You drink it black, and slowly: La Colombe Pure Black. It was the blind lineup's repeat pour — clean, chocolatey, actual finish. The per-ounce price is the tax on caring.
- You drink it daily, often with milk: STōK Un-Sweet Black. Ninety percent of the experience at a fraction of the cost, and it's in every store in America.
- You want one bottle that does everything: Chameleon Organic Concentrate. Iced, hot, latte, cocktail — it's an ingredient with range, provided you measure your cuts like you mean it.
The gap between them
Six points separate first from third, and the points live in specific places. La Colombe wins on taste and finish — the difference between "good cold coffee" and "coffee someone is proud of." STōK wins value outright and ties the field on ingredients and availability; its ceiling is a roasty edge that shows up as the glass warms. Chameleon trades polish for flexibility — scored per finished drink it hangs with the value leaders, but it demands more of you at pour time.
What surprised us blind: strength and quality are not the same axis. The strongest-reading pour was not the best-tasting one, and the "smoothest" marketing claim in the lineup finished last of the three on actual smoothness. This is why the labels stay hidden.
What we're testing next
The board is missing obvious contenders, on purpose — we'd rather publish three real scores than fifteen guesses. In the queue: Starbucks, Jot, Wandering Bear, Grady's, Bizzy, Trader Joe's, Kirkland (Costco), and Califia. Each gets the same blind pour and the same scale, and this leaderboard updates as they land. If there's a bottle you want on the record, the about page tells you where to find us.
