9: How do K-Cups work?

The inside of a K-Cup

Each K-Cup contains a paper filter that is “welded” inside the k cup.  In the production process, each k-cup is filled with coffee, tea, or hot chocolate and sealed with an airtight, foil lid.

To make a hot beverage, the K Cup is placed in a Keurig coffee maker and a mug is placed on a small platform below the brew head. The start button is then pressed, activating the brewer. Small holes are punctured in the bottom and top of the KCup, the brewer forces hot water through the K-Cup and the Keurig-brewed beverage is dispensed into the mug. The used K Cup can then be disposed of, and the Keurig coffee maker heats up water for the next cup.

  1. Of course this goes without saying that the used “disposable” K-cup is not recyclable and adds to the waste stream. The vast majority of the K-cup brew systems do not attain the necessary brew temperature of 200 F. The coffee is ground at the factory, and quite likely will have lost most of it’s aroma.

    Just be aware that for the convenience, the K-cup system really is not an improvement on brewing a good cup of coffee!

  2. Anyone know why K-cups dominated the market to almost exclusively eliminate the pod style system? What’s the supposed advantage? Just making the consumer buy new machines?

  3. I’ve used k-cups and have always wondered how the hot water gets in and out. The cutaway image was very helpful, thank you!

  4. Paul,

    They have a K-cup reusable filter where you can use your own coffee. That way you can freshly grind your own coffee and save the environment.
