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.
