Keurig is for machines of the same name and Nespresso pods are for machines of the same name.
They make refillable capsules for both, though. Mild pain in the butt to save a boatload of cash, though.
What is the big fuss about Keurig machines and the like?
They make utterly ghastly coffee, cost a fortune for a home-brewed drink, and waste TONS of plastic every day as well the machine itself is damnably expensive.
As you know, Keurig brewers take K-Cups, whereas coffee pod brewers use pods. The thing is the brewing chambers in each kind of brewer are separate.
In your Keurig brewer, both the top and bottom of each K-cup is pierced when you use it, and the water is pumped, under pressure, into the K-Cup itself.
The K-cup contains both the ground coffee and the filter. So Keurig cups cannot be used in Nespresso coffee makers.
If you want to make just one cup of coffee, get an espresso machine.
For the cost of a box of K-cups, you can get close to the best coffee on the planet. It’s not quite as convenient and not quite as quick, but there are benefits. They have different shapes and sizes.
However, you can buy a reusable pod. Open up a K-Cup and empty the coffee grounds into the reusable pod, and use the reusable pod. But you are better off using actual Nespresso pods.
UPDATE: I have been advised to update my credentials. I have tried and I cannot make any sense of the credential system. It would help if the “update credentials” message included a link to a brief how-to…
Furthermore, Nespresso cartridges can’t be used in a Keurig machine.
If you were looking to replace a weaker coffee, you’d be wise to use reusable cups that you can add your coffee too, so that you will get fresher tastier coffee.
But I would recommend that neither Keurig nor Nespresso are fresh coffee… it’s just not feasible for them to be fresh.
If you’re in any doubt, check the expiry date for one that is as far in the future as possible.
