How Many Times Can You Use a Keurig Cup?

Share and spread the joy of coffee

If you regularly enjoy a delicious cup of coffee from your Keurig, you may wonder, “How many times can you use a Keurig cup?” Using K cups regularly can really add up, both in terms of cost and the amount of waste produced. This often leads people to wonder if it would be possible to use a K cup twice.

A K cup is a sealed, tiny plastic cup with ground coffee inside. Once placed in the Keurig coffee maker, a metal needle pierces the K cup on the top and bottom. Next, it injects hot water into the K-cup, and it flows out of the second hole on the bottom of the K-cup.

There are four parts to the K cup: the outer plastic casing, a mini paper filter, coffee grounds, and the foil lid. The Keurig K cup is essentially similar to a mini drip coffee brewer.

The outer casing helps keep the coffee fresh until it is time to brew it. In addition, the filter is smaller than the paper filter you would use in a regular coffee maker. This serves to keep grounds out of your coffee.

The coffee grounds are measured so that there is a consistent flavor. This allows coffee drinkers to enjoy the same coffee flavor time after time. Finally, the foil seal is air-tight and designed to keep moisture, air, and light out of the coffee, which would affect the flavor of the coffee.

How many times can you use a Keurig cup?

K cups are designed to be single-use. It is not sanitary to reuse the cup unless it is a reusable K cup. Not only are there health concerns with reusing coffee grounds that water has already passed through, but the coffee’s flavor will also be affected.

If you use the same K cup twice, you will find the coffee watered down. As a result, the coffee will likely taste weak and gross. It certainly will not be a strong cup of coffee on the second brew.

When you reuse Keurig cups without adding new coffee to the pod, the coffee grinds will become over-extracted. This means that all the good flavors were already dissolved into the water when the first cup was prepared. As a result, the taste will be very bitter and weak. Overall, this will make bad coffee.

Many Keurig owners opt for this style of single-serve cups of coffee due to its simplicity and ease of use. You can prepare one delicious cup of coffee at a time using a K cup. However, a used K-cup will not produce as good of coffee as the first cup.

However, if you do not mind drinking weak coffee or if you plan to add a lot of cream or sugar to it, the weaker taste may not be too difficult to overcome if you reuse a K-cup.

Some people will reuse the K cup but replace the coffee grounds inside before brewing the second cup of coffee. This allows the plastic container to be reused but does not distort the taste of the second cup of coffee.

However, doing this requires a replacement lid for the pod. Therefore, this is not the best option if you want to use a K cup more than once. You are better off buying reusable K-cups designed for this purpose instead of creating a makeshift option for Keurig brewers (1).


Size of your beverage

While you should only use a traditional K cup once, you should recognize that Keurig cups will produce different tastes based on the size of the cup. For example, if you make a small cup of coffee, such as a 6-ounce cup, the K cup will make a strong coffee.

However, you will weaken the flavor if you choose to make 8-ounce or 10-ounce options. Keep this in mind if you plan to make a large cup of coffee and wonder how the coffee will taste.

If you want to fill a travel mug with strong coffee, you will probably need to use two K cups. This will add up to a lot of money spent. It will also generate more waste to make the strongest coffee.


Reusable options

Although they originally designed K-cups only to be used once, reusable options are now available. One such option is the Keurig My K-Cup Reusable Coffee Filter. With this option, you can make numerous cups of coffee without having to keep buying K cups.

These are more environmentally friendly, but you can save money by not having to replace the K-cup daily.

The reusable K-cup has four parts: the lid, the filter basket, holder, and the brewer adapter. Since Keurig makes it, the K cup will fit nicely in various Keurig machines.


How to use reusable K cups

First, take the lid off the filter holder. Then, turn it counterclockwise to pop the lid off. Next, fill the filter basket with coffee grounds.

You should only use this option for coffee grounds. It would be best if you did not use it with hot chocolate or green tea.

When you are done, twist the lid back on the top. It should be flat and seated firmly before you insert the filter holder into the machine. However, be cautious not to turn the lid too far. Otherwise, it could snap off and break.

For the reusable filter to go in the machine, you will need to remove the holder assembly from the Keurig. The holder apparatus will pop out easily. Then you can put the reusable filter in its place. The arrow on the lid should line up with the arrow on the Classic Series brewer.

At this point, you are ready to brew the coffee. Just lower the brewer handle and press the button to activate the process, just like you would if using a regular K cup.



They make reusable K-cups out of stainless steel or silicon. Both options are designed to last a long time. Typically, unless the user breaks the reusable pod, it will last the lifespan of your Keurig. This is an excellent K-cup option if you want the benefits of a pod coffee maker without the excess waste and expense of replacing the pods after each use.


Types of coffee

If you are refilling your K cup, you can choose the type of coffee you want to use. This is a real benefit, especially if you have a custom blend that you like to drink. Some people prefer to grind their whole bean coffee at home to be fresh.

You can use any type of ground coffee in a K cup. The variance in how finely the coffee is ground will affect its flavor. If you are adding your own coffee to a reusable K-cup, keep in mind that medium-fine ground coffee will produce the most flavor. Avoid using fine grinds, espressos, or coarse grinds to brew coffee in the Keurig.

If you like the Keurig coffee blend but want to reduce waste and cut down on the expense of single-serve K cups, you can buy Keurig coffee grounds to add to your reusable K cup. If you prefer the single-serve functionality of a Keurig but have a favorite coffee brand that is not available in single-serve pods, using a reusable K cup will allow you to enjoy the best of both worlds.



You will first dispose of the used coffee grounds to clean a reusable K cup. If your reusable pod has a paper filter, remove that too. Some utilize built-in filters, which does not apply to all reusable pods. Then, clean the used pod with warm soapy water.

Over time, you may notice some build-up in the filter. If so, soak it for about 30 minutes in a mixture of one part vinegar and two parts water. This will cause any remaining coffee to dissolve. If your reusable K cup has stainless steel components, it should not soak for more than 30 minutes. If they do, they may warp or get damaged.

Many reusable K cup options are even dishwasher safe for easier cleaning. However, they should be placed on the top rack to avoid exposing it to too much heat. When in doubt, be sure to check the manufacturer’s guidelines on whether to place your reusable pod in the dishwasher.


Enhanced K cup options

While the traditional K cup was designed only to make one cup of a beverage, such as coffee or tea, other options are available.

The K Carafe pods can make four to five cups of coffee. However, you will need a newer Keurig 2.0 machine to use this pod.

The K-mug pods are another option for preparing large amounts of coffee. These pods will make 12 to 16 ounces of coffee. This means you can enjoy the biggest cup of coffee or two regular-size cups without reusing K cups or sacrificing taste and quality.

How many times can you use a Keurig cup FAQ


Can I use a Keurig Cup twice?

While it is possible to use a Keurig cup twice, you should be aware that the coffee will be very weak and probably taste bad. Also, a reused K cup will likely just look like brown water.


Can you use a coffee pod twice?

While you technically can use a coffee pod twice, doing so is not advised. Instead, if you want to save money on coffee pods, consider buying a reusable filter to add your own coffee grounds and continually reuse the same pod without negatively affecting the taste of your cup of coffee.


What happens when you reuse a Keurig Cup?

When you reuse a Keurig cup that is only designed to be used once, the result will not be good coffee. A second cup brewed from the same K cup will not extract the full flavor from the used coffee grounds. However, the first brew will taste much better than subsequent brews from the same K cup.


How many cups of coffee can a Keurig pod make?

A Keurig machine is designed to make single-serve cups of coffee. One K cup pod will make one cup of coffee. If you want a stronger brew, choose the six-ounce cup option. You can choose to brew a larger size cup, such as 8 ounces or 10 ounces, but the coffee will taste weaker.
