I haven't tested every decaf that I've tried for maximum usable life, but 7 or 8 days is usually when I detect a distinct turning point. I have a small flat-burr grinder, and for regular beans I only get 10 to 12 days of good life. (I've often wondered if a large conical grinder would get me a couple of more days of life.) So for me, decaf is roughly two-thirds the life of regular beans. I'm in the opposite mode of most people, my regular beans often get frozen, but my decaf gets consumed rapidly.
