How Much Coffee Is There in a Reusable K-Cup?

If you love the convenience of your Keurig single-serve coffee machine, you’ve probably thought about getting a reusable K-cup. Reusable K-Cups are one of the fastest and easiest ways to make coffee. So, how much coffee is there in a reusable K-cup? And does it save you any money?

How Much Coffee Is There in a Reusable K-Cup?

Ground coffee in an average reusable K-Cup is about 0.3-0.4 ounces, the same amount as 2 tablespoons per 6–8 ounces of water. The precise amount of coffee inside your K-Cups varies by brand and roast. Typically, darker roasts contain more dry matter by volume and weight.

What Are the Benefits of Using Reusable K-Cups for Making Coffee?

More than 75 million homes are drinking coffee from single-use pods every day. This means that tens of billions of nonreusable, nonrecyclable plastic pods have ended up in landfills thanks to companies like Keurig.

This number is growing exponentially as more companies join the industry. Switching to reusable Keurig-Cups is a better alternative.

More Flexibility

If you don’t like your coffee as strong or as weak as it comes out when using a reusable Keurig -cup, you can adjust how much ground coffee you use and the amount of water used to get the taste that suits your preferences best. This makes it much easier than changing the settings on an espresso machine or other similar appliance that might have preset options available.

Environmentally Friendly

Disposable K-Cups have been known to be a major contributor to environmental pollution. This is because they are made from plastic that can take up to 500 years to break down naturally. The problem is that so many of them end up in landfills, while others end up in the oceans, where they pose a great threat to marine life.

Reusable K-Cups help reduce waste by allowing people to make their own coffee rather than buying pre-made pods or capsules. This way, they eliminate the need for single-use K-Cups.

Cost Saving

One of the main reasons for using reusable K-Cups is that it can save you a lot of money, especially if you’re buying them in bulk at wholesale prices. You don’t have to throw away those expensive K-Cups anymore. They’re completely reusable; use them repeatedly with any kind of coffee you want!

What Factors Influence How Much Coffee to Use in a Reusable Keurig -Cup?

The coffee you use in a refillable Keurig cup will vary based on a few factors, including the type of coffee you’re brewing and your taste preferences.

The Brand

The brand itself is something to consider when determining how much coffee to use in your reusable Keurig-Cup. Some brands offer stronger brews than others, which can affect how many grounds you need per cup of coffee.

For example, Starbucks offers a stronger brew than Dunkin’ Donuts does. Therefore, although both brands have same-ounce K-Cups, Starbucks contains more grounds than Dunkin Donuts because its strength allows for fewer grounds per cup.


The grind of the coffee is one of the most important factors when determining how much coffee to use in your refillable Keurig Cup. If you have a coarse grind, you will need more grounds than a fine grind. This is because the extraction rate of grounds is proportional to the surface area.

Finer grinds have more surface area and can reduce the flow of water hence low contact time than coarse grinds. You, therefore, need fewer grinds to achieve your desirable coffee.
