DISCOVER THE BEST CANNED COLD BREW COFFEE

Most "best canned cold brew" lists are ad placements with no data behind them. This one leads with an actual comparison: four black, unsweetened canned cold brews ordered by caffeine per fluid ounce, with sugar and ingredient counts taken straight from published label data.

Canned Cold Brew, Compared by Caffeine per Ounce

Every black canned cold brew below is listed by caffeine per fluid ounce (mg/fl oz), with sugar and ingredient counts straight from the published nutrition panels. Same metric for everyone, no pay-to-play. Every SKU is named in full, because sizes and variants within one brand carry very different numbers.

#	Product (SKU)	Serving	Caffeine	mg / fl oz	Sugar	Ingredients
1	Bare Brew ★	12 fl oz can	320mg	26.7	0g	2
2	La Colombe Cold Brew Black	9 fl oz can	180mg	20.0	1g	—
3	High Brew Black & Bold	8 fl oz can	140mg	17.5	Cane sugar declared	—
4	Starbucks Nitro Cold Brew Black Unsweetened	9.6 fl oz can	155mg	16.1	0g	—

What the numbers mean

Bare Brew, 12 fl oz can (26.7 mg/fl oz) — 320mg per can. Two ingredients: filtered water and Honduran Arabica coffee. 20 calories, 0g sugar, 5g total carbohydrate.
La Colombe Cold Brew Black, 9 fl oz can (20.0 mg/fl oz) — 180mg per can, with 1g of sugar on the panel. La Colombe's 11 fl oz Black Unsweetened can is a separate SKU at 220mg (20.0 mg/fl oz).
High Brew Black & Bold, 8 fl oz can (17.5 mg/fl oz) — 140mg per can. Note that "black" is doing some work here: cane sugar is a declared ingredient.
Starbucks Nitro Cold Brew Black Unsweetened, 9.6 fl oz can (16.1 mg/fl oz) — 155mg per can, 0g sugar, 10 calories. This is the Starbucks RTD SKU with a published caffeine figure in a single-serve can. Starbucks' 11 fl oz Black Unsweetened bottle does not publish a caffeine figure at all — its SmartLabel panel carries no caffeine value — so it is not listed here. Starbucks' 40 fl oz Black Unsweetened multi-serve bottle publishes 255mg per 12 fl oz serving (21.3 mg/fl oz), but it is a multi-serve bottle rather than a single-serve can, so it sits outside this table.

Methodology: black/unsweetened single-serve canned cold brew only — no lattes, no sweetened lines, no multi-serve bottles. Caffeine and nutrition come from published label data, transcribed in our label-transcribed caffeine dataset, checked September 2026. mg/fl oz = label caffeine ÷ serving fluid ounces. This is a four-product comparison, not a survey of the whole category: several other cold brews — including RISE Original Black (11 fl oz can, 270mg, 24.5 mg/fl oz) and Wandering Bear Original Black (8 fl oz can, 200mg, 25.0 mg/fl oz) — carry more caffeine per ounce than most of this table. Where a brand does not publish a caffeine figure, we state that rather than estimating one. Formulas change — if a label updates, tell us and we will update the table.
