Cold brew isn't just coffee—it's concentrated caffeine delivered straight. But "strong" means different things depending on who you ask. Are you chasing the highest mg count per can? The most caffeine per ounce? Or clean energy without the sugar crash?
At Bare Brew, we've stripped cold brew down to its essence: coffee, water, 0g sugar, and 320mg of pure caffeine in every 11oz can. But how does that stack up against other brands claiming "strongest" status? Let's break it down.
What Actually Makes Cold Brew "Strong"?
Cold brew strength isn't just about total caffeine. It depends on three factors:
- Caffeine per ounce (mg/oz): The actual concentration in each sip. Higher mg/oz means faster energy delivery.
- Total caffeine per serving: How much you get in the whole can or bottle.
- What else is in it: Sugar, additives, and other ingredients either amplify or muddy the clean energy effect.
A 320mg can that's 11oz delivers 29.1mg of caffeine per ounce—significantly more concentrated than standard coffee. But let's see how the major brands actually compare.
Cold Brew Caffeine Comparison Chart
Here's the breakdown of seven of the most popular "strong" cold brew brands on the market:
| Brand | Caffeine (mg) | Size (oz) | mg per oz | Sugar (g) | Price |
|---|---|---|---|---|---|
| Bare Brew | 320 | 11 | 29.1 | 0 | $3.49 |

What the Numbers Actually Mean
1. Death Wish is the absolute strongest (but at a cost)
Death Wish Coffee contains 660mg of caffeine—making it the highest total caffeine on the market. However, it exceeds the FDA daily limit in a single serving.
2. Bare Brew is the strongest balanced option
At 29.1mg per ounce, Bare Brew ranks second in caffeine concentration—significantly ahead of Starbucks (20.5mg/oz) and Chameleon (24mg/oz). The difference? Zero sugar, zero additives, and a cleaner price point.
3. Most mainstream brands don't deliver "strong"
Starbucks, High Brew, and Chameleon all sit in the 20-24 mg/oz range. Many also contain added sugar or other ingredients that dilute the clean caffeine experience.
Who Actually Needs the Strongest Cold Brew?

- Long-haul workers: Developers, remote workers, and shift workers who need sustained energy without crashes.
- Caffeine-tolerant drinkers: If you're already drinking multiple cups of coffee, strong cold brew keeps energy high without volume.

Safety, FDA Guidelines, and Smart Caffeine Intake
The FDA recommends healthy adults consume no more than 400mg of caffeine per day. That means:
- Bare Brew (320mg per can): Safe as your daily caffeine source with room for other beverages.
- Death Wish (660mg per can): Exceeds daily limits in a single serving.
- Pregnant or nursing: Limit caffeine to 200mg/day—consult your doctor.
- Caffeine sensitivity: Start with standard cold brew amounts to assess tolerance.
Frequently Asked Questions
Is 320mg of caffeine safe to drink every day?
Yes, 320mg falls within the FDA's 400mg daily recommendation for healthy adults. Monitor total intake if you drink multiple caffeinated beverages.
Does cold brew have more caffeine than hot coffee?
Cold brew typically has slightly more caffeine than the same volume of hot coffee because of the longer steeping time. Bare Brew's 320mg puts it in the "strong cold brew" category.
What's the difference between cold brew and cold brew concentrate?
Cold brew concentrate is a stronger base diluted before drinking. Ready-to-drink cold brew (like Bare Brew) is already mixed and ready to consume.
Is Death Wish Coffee really stronger than Bare Brew?
Yes—660mg vs 320mg. However, "strongest" doesn't mean "best." Death Wish exceeds FDA daily limits in one serving. Bare Brew delivers the high-caffeine punch most people actually need, without excess.
Why does Bare Brew have 0g sugar when other brands don't?
We don't add it. Bare Brew uses only coffee and water. Read more about why zero sugar matters.
What's the best time to drink strong cold brew?
Morning or early afternoon. Caffeine takes 15-45 minutes to peak. Drinking after 3 PM can interfere with sleep.
