Most coffee sites state that you must use up the coffee within a week for the best flavor/freshness. I make one pot (4 cups) per day, so a pound will last me a couple of weeks + easily. I like to buy through the mail (Peets, Intelligenstia etc), so I always buy 2 pounds at a time, as I think it would be too costly just to buy one pound with the shipping costs. How much coffee do you burn through, and do you have any trouble with freshness after a week?
