I buy two 3# bags of (shudder) Starbums regular, and one 3# bag of Cinnamon Hazelnut for a little "foo foo" action, and mix them thoroughly in a large air tight container, which is used to replensish the smaller air tight coffee container on the counter.
No freezing or refrigerating.
We use a Cuisinart Grind and Brew for making the coffee every d@mn day.
Cuisinart - DGB-600BC
Bean count = 1/2 cup for each pot, (four scoops of 1/8 cup each) and brew using a paper filter as opposed to the metal mesh basket (less grit in the cup).
The beans last more than a few weeks, but I get the blend that satisfies both my wife and I, and there is no really noticeable deterioration of the flavor during that time.
The Grind and Brew really makes a difference with the thermal carafe (no continuous "boiling" of the coffee after the intial brewing)...
