Quick Answer
If you grabbed a bottle of STōK cold brew and want to know exactly how much caffeine you are dealing with, here is the short answer. STōK cold brew contains approximately 120 to 170mg of caffeine per serving, but that number shifts depending on which product you pick up. The single serve bottles, the big 48oz jugs, and the energy line all sit at different levels.
Most people just want to know if it is going to hit hard or be manageable. This breaks it all down by product so you are not guessing.
What Makes STōK Different From Regular Coffee
Before getting into numbers, it helps to understand why cold brew caffeine works a bit differently than your regular morning cup. STōK brews using a higher ratio of coffee to water than typical hot brewing, and instead of using heat to force flavor from the bean, they steep at lower temperatures for 10 slow hours. That process pulls a smooth, bold flavor without the bitterness, but it also means the caffeine content per ounce runs higher than what you get from a standard drip coffee.
Factors like coffee bean type, ratio, grind size, water temperature, and brew time all affect how much caffeine ends up in the final cup. STōK uses Arabica beans sourced from Central and South America, which land on the milder end of the caffeine spectrum compared to Robusta, but the cold brew method and bean-to-water ratio more than make up for that.
How Much Caffeine Is in STōK Cold Brew by Product
This is where it matters to be specific because the range across the STōK lineup is pretty wide.
STōK Original and Unsweetened Black (48oz Bottle)
This is the one most people buy at the grocery store. The 48oz bottle of STōK unsweetened cold brew contains 125mg of caffeine per 12oz pour. That is a solid amount. It sits comfortably above a standard shot of espresso, which runs around 63mg, and it is close to what you would get from a large drip coffee.
STōK Single Serve Bottles (13.7 oz)
The smaller ready-to-drink bottles are more concentrated per bottle. A 13.7 fl oz bottle of STōK cold brew contains 145mg of caffeine total, which works out to about 10.58mg per fluid ounce. If you drink the whole bottle in one sitting, which most people do since it is a single serve, you are getting a meaningful caffeine dose in one go.
STōK Cold Brew Energy Line (Canned)
This is the strongest product in the lineup and is built more like an energy drink than a straight cold brew. STōK Cold Brew Energy drinks contain 195mg of caffeine per serving and also include B-vitamins, guarana, and ginseng. If you are sensitive to caffeine or just want a moderate boost, this is not the one to start with.
STōK Decaf
For people who love the taste of cold brew but want to skip the stimulant, STōK does make a decaf version. The decaf removes about 97% of the caffeine using the European Method, which is FDA approved, in line with other decaf coffee products. You are still getting a trace amount but nothing that will affect most people.
Is STōK Cold Brew High in Caffeine Compared to Other Drinks
To put it in perspective, here is how STōK stacks up against some common options most people are already familiar with. A regular 12oz cup of drip coffee runs around 95 to 120mg of caffeine depending on the roast and brew strength. STōK at 125mg per 12oz is slightly above that range. A standard Red Bull is 80mg per 8.4oz can.
A Starbucks grande cold brew comes in around 205mg for 16oz, which is higher per serving but also a larger drink. So STōK is not the most caffeinated cold brew on the market, but it is not light either. For most adults, one serving of the standard product is a reasonable daily amount. Two servings gets you close to the 400mg daily limit that health authorities generally recommend for healthy adults.
What Affects Caffeine Levels in Your Cup
Even when you are buying the same product, your actual caffeine intake can shift depending on how you drink it. Pouring over a lot of ice dilutes the liquid but does not remove caffeine. You still get the same total milligrams, just spread across more volume. Adding milk or creamer also does not reduce caffeine. It just changes the flavor and calorie count.
If you are drinking from the 48oz bottle, the pour size matters more than people realize. STōK lists 12oz as a serving, but plenty of people fill a full cup with ice and pour well over that. Keep that in mind when tracking your intake.
Who Should Watch Their STōK Intake
For most healthy adults, STōK cold brew is completely fine as a daily drink. The caffeine levels are meaningful but not extreme in the standard products. That said, if you are pregnant, caffeine-sensitive, dealing with anxiety, or managing a heart condition, 145mg in a single bottle is worth paying attention to.
The Energy line at 195mg plus added guarana pushes things further and is better treated as an occasional choice rather than a daily habit. Teenagers and kids should avoid it entirely. The caffeine content is calibrated for adult consumption and the Energy line especially is not appropriate for younger drinkers.
Conclusion
STōK cold brew sits in a practical middle ground. Not the weakest thing on the shelf, not the most aggressive either. The standard 48oz bottle gives you 125mg per 12oz serving, the single serve bottles come in at 145mg per bottle, and the Energy cans push up to 195mg with added ingredients. Know which product you are buying, keep your pour size in mind, and it is an easy coffee to work into a daily routine without overdoing it.

FAQ’S (Frequently Asked Questions)
It depends on the product. The standard STōK 48oz bottle gives you 125mg per 12oz serving, which is slightly above what most drip coffee delivers. The single serve bottles and Energy line push higher than that. So yes, for the most part STōK runs stronger than a typical home brewed cup, but it is not extreme compared to something like Starbucks cold brew.
For most healthy adults, one serving a day is completely fine. The caffeine sits within a reasonable range and should not cause issues for people without existing sensitivities. Where it gets worth watching is if you are also drinking other caffeinated drinks throughout the day. Stack a couple of coffees on top of STōK and you can easily go past 400mg, which is the general daily limit most health guidelines point to.
Yes, by a fair margin. A standard Red Bull has 80mg of caffeine in an 8.4oz can. A single serve STōK bottle has 145mg in 13.7oz. Even the standard 12oz pour from the big bottle at 125mg clears Red Bull comfortably. The Energy line at 195mg is not even close.
