How long do roasted beans last?

[jacob]

I have some downtime while I repair one of my machines, and I thought I'd get a head-start on some roasting so that when the part and a second grinder come in I can hit the ground running with some roasted, cracked, winnowed nibs ready to go. How long would you keep your roasted nibs for before grinding? A week? A month? 24 hours?

There's a very good ATA on that, #78

I figured this was asked, but couldn't find the right search keywords. Thanks!
