BUYING OLD BEANS“Make sure you choose a coffee with a roast date, not a ‘best by’ date. Preferably, that date should be no longer than a week ago. Then use it up, share it with friends, or buy smaller bags so you move through it quickly. Sometimes lightly roasted coffee can be good for a couple of weeks after opening, but in general, fresher is better.”
GRINDING IN ADVANCE“Buy whole-bean coffee. Ground coffee gets stale really easily. Buying a grinder just isn’t that hard: It’s not that expensive, and doesn’t take that long. If you’re doing the pulse-and-shake method on a cheapo blade grinder, I think you’re still better off than buying pre-ground coffee that’s been sitting in a bag for a week or God knows how long.
