In my experience, grocery stores want a best by, not a roast date, so even good roasters will sometimes use a different label when selling through a store vs direct. In one case, I learned the best by date they use is just roast date + 1y.

My local Target has started carrying high(er) end coffee beans — Stumptown, Peets, Blue Bottle, Counter Culture, etc. Interestingly, these bags DO show a roasted date on them. When I eyeballed it, they were all about 5-6 weeks prior, so not straight from the roaster but not horribly old either.
