It's possible to bring the consummate brewed cup of coffee home with the Keurig coffee brewer. Using the Keurig, it is best to remove the K cup right after brewing a cup. This avoids leaving a taste of the previous brew in the brewer. Before putting the K cup in the brewer, make sure that the crystals of whatever flavor source you are using are shaken up. This effort spreads the flavor in a nice way. Do not put the Keurig coffee brewer in the dishwasher. Savor it and wash it by hand, and it will last for many years.
Gevalia coffee pods are the individual, single-sized coffee baskets used in a Gevalia coffee pod brewer. The pods come in several flavors of coffee and make just a single cup. There are several ways to purchase them.
