How To Store Coffee I was always told years ago to freeze opened coffee bags (or leftover freshly ground), and I usually have about 7-8 different bags of coffee in air tight bags in my freezer most of the time. But recently I've been reading that you shouldn't do that at all! I'm confused....what exactly is the best way to store coffee if I don't drink it too often (once a day), but like to have different types of coffee available? I don't want to waste a bag of coffee and throw out what I don't use after a couple of days since I only drink about a cup per day. Also, if it is bad to freeze it, why...what happens to the coffee? Seems to taste okay to me.
Not being a chemist, I'll say that freezing things do somewhat bad things to the taste of what you're freezing, whether it is meat, fish or coffee. Of course, just leaving it on the counter top might be worse, whether, again, it is meat, fish or coffee. In other words, frozen coffee is better than old coffee.;)
The best way to store your coffee is whole (as in not grinded), dark, dry and *short*.
The key is that it tastes OK to you. There's a debate in the coffee community on this issue, but I think freezing often makes sense. Coffee beans are at their peak a few days after they were roasted. At room temperature, beans slowly get stale, and ground coffee gets stale very fast. After a couple of weeks, beans have deteriorated noticeably, and they'll keep getting worse. When I buy fresh coffee beans, I'll keep about a week's supply at room temperature, and freeze the rest. Once frozen, my experience is that coffee stays very stable for many weeks. It won't taste quite as glorious as when it was first roasted, but it will taste a lot better than coffee that's been at room temperature for a long time. Ideally, I'd buy coffee once a week, or roast at home, but for the sake of convenience, I buy beans (very good and very fresh beans from specialty suppliers) every three or four weeks.
