How Much Caffeine Is in a K-Cup? By Brand and Brew Size

How Much Caffeine Is in a K-Cup? By Brand and Brew Size

A standard K-Cup pod brews a cup with 75 to 150 mg of caffeine per 8 oz, according to Keurig's own support pages. Decaf K-Cups contain 2 to 4 mg. Caffeinated tea pods land at 50 to 75 mg per cup. High-caffeine pods push higher: Death Wish Coffee lists its single-serve pods at 140 to 210 mg per 6 oz cup, with Power Surge topping out around 210 mg.

Keurig's US product listings show only "Regular," "Half Caff" or "Decaf" as a caffeine filter and print no milligram figures (checked Oct 31, 2026 on keurig.com). The Keurig ranges above come from Keurig's Canadian support page, published by Keurig Dr Pepper. Death Wish states each figure is approximate and based on a 6 oz serving brewed per package instructions. Actual caffeine varies with roast, crop and brew conditions.

Does a bigger brew size mean more caffeine?

Keurig states its 75 to 150 mg range for an 8 oz cup, and Death Wish states its figures for 6 oz. Neither publishes numbers for 10 or 12 oz settings.

Each pod holds a fixed weight of coffee. A larger cup setting pushes more water through the same grounds, so per-ounce concentration drops. Keurig notes that iced-coffee pods are packed with extra coffee to stay bold when brewed over ice.

Which K-Cups have the most caffeine?

Among brands that publish a number, Death Wish Power Surge leads at about 210 mg per 6 oz cup, 20% above Death Wish Dark Roast at 180 mg (Death Wish product page). Valhalla Java sits at 175 mg, Medium Roast at 165 mg, Espresso Roast at 155 mg, and Light Roast at 140 mg.

Starbucks sells a 2X Caffeine K-Cup that blends House Blend with coffee extracts for "twice the caffeine of Starbucks coffee in a traditional K-Cup pod" (Starbucks At Home). The actual milligram count is not published on Starbucks' page. For Folgers, Green Mountain and Dunkin', caffeine per pod is likewise not published by the brand.

K-Cup vs drip coffee vs espresso

Keurig's K-Cup FAQ gives the same 75 to 150 mg per 8 oz range for coffee in general that it gives for K-Cups. By Keurig's own numbers, then, a pod is not inherently weaker or stronger than drip: caffeine depends on the coffee and how much of it is used, not the brew format.

Espresso is a different comparison. Keurig notes a 1.4 oz shot at roughly 50 to 75 mg, less per shot than a full K-Cup but far more per ounce. Keurig also says that "the darker the coffee is roasted, the less caffeine it contains." More on roast level and caffeine, or see the full caffeine in a cup of coffee guide and the Nespresso pod caffeine chart.

Decaf, tea and specialty K-Cups

Decaf K-Cups run 2 to 4 mg of caffeine per 8 oz cup, according to Keurig. That is not zero. Keurig cites the industry standard of at least 97% of caffeine removed for a coffee to qualify as decaf, which means a small amount always remains.

Most caffeinated tea K-Cups fall in the 50 to 75 mg range per cup. Specialty beverages (hot cocoa, chai lattes, flavored drinks) contain little to no caffeine, but those made with tea, coffee or chocolate may reach up to 60 mg per 8 oz serving.

How many K-Cups fit in 400 mg a day?

At Keurig's top figure of 150 mg per cup, two pods total 300 mg and stay well under the FDA's 400 mg daily guideline for most healthy adults. A third cup at that level pushes to 450 mg, past the line. Two Death Wish Power Surge cups hit about 420 mg. Count every other caffeine source in your day, including tea, soda, pre-workout or a caffeine pouch, to stay under the total. More detail in how much caffeine is too much.

Who should watch K-Cup caffeine

• Pregnant, trying to conceive or breastfeeding: The FDA advises talking to your health care provider about caffeine intake.
• Children and teens: The 400 mg figure is for adults. The FDA notes that too much caffeine in children and teens can raise heart rate and blood pressure and disrupt sleep, so limit or avoid caffeinated pods.
• Heart rhythm conditions, anxiety disorders or stimulant medications: Talk to a clinician before adding caffeine.
• Rapid high-dose intake: The FDA estimates toxic effects, including seizures, can occur with rapid consumption of around 1,200 mg of caffeine.

Frequently Asked Questions

Is there more caffeine in a K-Cup than in regular coffee?

Not necessarily. Keurig publishes the same 75 to 150 mg per 8 oz range for both K-Cup pods and coffee brewed by other methods. The caffeine depends on the roast, the bean and how much coffee is in the pod or scoop, not the brewing format itself.

Does Keurig list caffeine on its pods?

Keurig's US product pages (keurig.com) show a caffeine level filter of Regular, Half Caff or Decaf, but they do not print a milligram figure per pod (checked Oct 31, 2026). Keurig's support pages give the 75 to 150 mg range for all standard K-Cup coffee.

How much caffeine is in a decaf K-Cup?

Keurig puts a decaf K-Cup at 2 to 4 mg per 8 oz cup. Decaf is not caffeine-free; the decaffeination process removes at least 97% of the caffeine, leaving a trace amount in every cup.

Can I reuse a K-Cup for more caffeine?

No brand publishes caffeine data for a second brew through a used pod. A second pass runs water through already-extracted grounds, so the cup will be weaker in both flavor and caffeine. A fresh pod is the more reliable option.

One Pouch, Not Another Pod

A K-Cup gives you one window of caffeine, usually 75 to 150 mg, and you finish it in ten minutes. If you want that morning lift to carry into the afternoon without brewing a second or third cup, the issue is duration, not dose.

Roon is an 80 mg caffeine pouch, placed under the lip, that pairs caffeine with 25 mg methylliberine (Dynamine). In a randomized, double-blind crossover study (n=12), methylliberine co-administered with caffeine cut oral clearance from 41.9 to 17.1 L/hr and extended caffeine's half-life from 7.2 to 15 hours, with no rise in peak concentration (Mondal et al. 2022, Journal of Exercise and Nutrition). That study dosed 100 mg methylliberine + 150 mg caffeine, roughly 4x and 1.9x what a single Roon pouch contains, so the mechanism applies directionally rather than as an exact match. That 15-hour half-life measures how slowly caffeine clears, not how long you feel it; a single Roon pouch is felt for about 6 to 8 hours, well past the point where a pod's caffeine usually fades. Finish your last pouch at least 8 hours before sleep.

One pouch puts you near the low end of Keurig's per-cup range. A second brings you to 160 mg when you want more. Limit is 4 pouches a day, and the 400 mg budget includes your coffee. Roon costs from $9.16 per tin. Try Roon.
