How much caffeine do you think is packed into those convenient K-Cups? I admit it’s a bit of a puzzle since different brands and blends offer varying levels of caffeine.

But here’s the scoop: depending on the type of beans, a standard cup of coffee made with a normal K-Cup has 75 to 150 mg of caffeine.

Here’s a quick K-cup caffeine content chart for all different types of pods!

How much Caffeine in a K-Cup?

K-Cup Coffee pods typically contain between 75 and 150 mg of caffeine per 8 oz cup (250 ml). The caffeine content in a K-Cup can vary depending on the type of coffee beans, roast level, and the amount of coffee in the pod. The amount of caffeine in K-cup Coffee is almost the same as regular coffee brewed through drip brewing methods.

Robusta coffee beans generally have more caffeine than Arabica beans, so coffee pods made with a blend of Robusta and Arabica beans will have more caffeine.

Arabica coffee beans, known for their smooth flavors and enticing aroma, contain slightly less caffeine (8-10 mg/g), while Robusta coffee beans, which have a bitter taste and are often used in coffee blends for their higher caffeine content, contain around 18-20 mg/g.

Here is the caffeine content in various K-cup beverages per 8 oz serving:

Beverage Caffeine Content 
Regular Coffee75-150 mg
Decaffeinated Coffee2-4 mg
Espresso K cups100 – 170 mg
Herbal Tea0 mg
Green Tea25-45 mg
Black Tea40-50 mg
Specialty Beverages (Latte, Cappuccino)60 – 80 mg

How many coffee grounds are in a K-Cup?

There are usually 9 to 12 grams (0.3 to 0.4 ounces) of medium-sized coffee grounds in a K-Cup. This translates to approximately 1.5 to 2 tablespoons of coffee. The specific amount can vary depending on the brand and roast level.

Darker roasts, for example, may have slightly more dry matter in terms of volume and weight.

Many Coffee lovers argue that the amount of coffee in K-Cups produces a weaker brew. Especially when using larger brew sizes.

The best coffee-to-water ratio for a delicious cup of coffee is around 1:15 to 1:17. That means the amount of coffee in a K cup is only good for preparing 5 to 7 ounces of coffee.

That’s why I always recommend choosing a 6 oz brew size for a flavorful and strong cup of Keurig coffee.

Does roast affect the caffeine content in a K-Cup?

While lighter roasts contain slightly more caffeine than darker roasts, generally the roast level doesn’t have a significant impact on the caffeine content of a K-Cup.

Caffeine content is not affected by typical roasting temperatures, and even the darkest roasts rarely reach temperatures that would alter caffeine content significantly during the roasting process.

While roasting does not impact caffeine levels, it does influence other physical properties of the coffee, such as its size and weight. As coffee beans roast, they lose moisture and expand in size.

Dark roasts have less caffeine due to the fact that the beans expand when roasted. So volumetrically they will have less caffeine; however, when comparing light and dark roasts by weight, the caffeine is almost equal.

Does Keurig cup size affect caffeine?

No, the Keurig cup size does not affect the amount of caffeine in the drink. Whether you choose a 6 oz, 8 oz, or 10 oz cup size, the caffeine content remains the same. However, the smaller cup sizes will obviously be more concentrated in caffeine.

This is because the Keurig pod contains a pre-measured amount of coffee that determines the caffeine content, regardless of the volume of water used for brewing.

There can be slightly more caffeine in larger cup sizes due to the extended brewing time. (But obviously, they will be weaker and less concentrated)

Some Keurig models come with a strong button that slows down the brewing process and extracts more flavor from the grounds, resulting in slightly more caffeine in your cup.

How much caffeine is in Starbucks K-Cups?

On average, a Starbucks K-Cup contains approximately 100 to 130 milligrams of caffeine per 8-ounce cup of coffee. Starbucks also offers “2 X Coffee pods” that have twice the amount of caffeine (around 250 to 260 mg) than normal K cups.

Starbucks offers a range of K-cup coffee pods with varying roasts and flavors, including light roasts like Veranda Blend, medium roasts like Breakfast Blend and Pike Place, and dark roasts like Caffe Verona and French Roast.

Additionally, they also have special offerings like Holiday Blend and flavored options such as Cinnamon Dolce.

How much caffeine is in Folgers K-Cups?

On average, a Folgers K-Cup contains approximately 75 to 120 milligrams of caffeine per 8-ounce cup of coffee. Folgers offers a variety of K-cup flavors and blends with different amounts of caffeine.

Folgers also offers half-caffeinated or completely decaffeinated K-cup pods for those who enjoy the flavor of coffee but want to avoid caffeine altogether.

K-Cups with no caffeine | Decaffeinated pods

It’s important to note that even though the decaffeinated k cups are marketed as “no caffeine K cups” they still contain a trace amount of caffeine.

The international standard for decaffeinated coffee requires that 97% of caffeine must be removed from the beans

So decaf coffee pods generally have 2 to 4 mg of caffeine in a normal 8 oz serving of coffee.

Here are some of the best decaf K cup pods.

The Original Donut Shop

The Original Donut Shop decaf K-cups offer delightful decaffeinated pods without compromising on flavor.

  2. My coworker brought in these extra strong Death wish K cups last week. One cup and I was wired for hours!
    They literally have huge amount of caffeine compared to normal K cups. Maybe good for an all-nighter but too intense for my daily use.
