You can use Gevalia coffee with the Keurig, but you're best off buying the regular coffee from Gevalia instead of the tassimo t-cups. The t-cups themselves will not work with the Keurig, but you can buy cups (mine was an ekobrew) that are the same size and shape of the k-cups and you can put any kind of coffee in it, close the lid, pop it into the keurig and start brewing. They are very nice too because you can adjust the amount of coffee you want in it and make it stronger or lighter. The only down fall of this is the clean up of the k-cup afterwards, but they are dishwasher safe and it's worth it to have Gevalia Coffee!
