Can I use the same K-Cup twice?

Using one K-Cup to make two small cups of coffee.

Using one K-Cup to make two small cups of coffee.


I was recently given a Keurig brewer as a gift. I really like it, but am not crazy about the cost of the K-Cups. The machine is great, but it’s costing me a lot more to buy coffee than I’m used to.

So here’s my question. Can I use the K-Cups more than one time? I had read elsewhere that it’s Ok to use them twice.

What do you think?


Well, put simply, I think that anyone who is happy with a second cup of coffee from the same K-Cup has a very low threshold when it comes to enjoying their coffee!

K-Cups are designed to be used once and then thrown away.

Many will argue that there isn’t enough coffee in a K-Cup to make even one decent brew.

Anyway, take a look at the photo above.

I took a single K-Cup and used it to make two 6-ounce cups of coffee. That’s small cups, not mugs, which are more like 8 or 10 ounces each.

On the left you can see the first 6-ounce cup of coffee. Nice and dark. A decent brew.

On the right is the second 6-ounce cup of coffee I brewed, using the same K-Cup. As you can see, it is light and thin.

Yes, I tasted both. The one on the left – the first brew from the K-Cup – was just fine. The one on the right – the second brew from the same K-Cup – was thin and tasted like dishwater.

In other words, if you like a decent cup of coffee, never use the same K-Cup twice. In addition to getting a weak cup of coffee, it will fail for another reason too.

When you use the same coffee grinds more than once, the coffee becomes over-extracted. The good flavors have already been dissolved into the water the first time around.

The second time around, that over-extraction creates a nasty bitterness.

Weak coffee. And bad coffee.

As for the cost of K-Cups, I hear you. It’s a very expensive way to make your daily brew.

That’s why I always use a reusable filter, and fill it each time with my own coffee. This cuts back on the price and also reduces the environmental damage from throwing away hundreds of used K-Cups each year.

The reusable filter I use is the Keurig My K-Cup Reusable Coffee Filter.

I hope this answers your question!

Is a 10 oz cup less potent than an 8 oz or 6 oz? If so, why brew anything larger than the 6 oz??

I find that the teas are so strong I can get 3 cups o 8 oz tea out of one kcup

As for the cost of them

I believe amazon is cheaper than stores. If you go to amazon and search there.. You can get like a 92 variety pack I believe for like 8 dollars. It may not be exactly as cheap as the other ones.. But it does help :)

Go big or go home

If this is the case then it only makes sense ot make the biggest cup of coffee your keurig can make. Right? Take full advantage of whats in there.

But then the comment about a 6oz then taking it out and shaking it makes me wonder, will have to try that.

Add to the second weaker brew, a table spoon of instant hot coco. Turns out pretty good.

I tried it and I thought that tasting like dishwater was a compliment. Awful.
