This is a question that is asked a lot. Some people are NOT like the bean 5 and need to store their coffee. (see we go through it SO fast that there is really no need for us. We consume well within the 7-14 day period)
Before I answer your question though, Let's make sure we have a solid understanding of what’s happening to your coffee and why your asking the question in the first place.
Throughout coffee’s life-cycle, it is going through constant chemical and physical change. That doesn’t end when it’s roasted. In fact, it speeds up. Not only does the roasting dramatically change the coffee itself…But afterward, it continues to give off gasses and go through physical and chemical changes within the bean. We like to say that the ‘golden time’ for the freshness of coffee is about 4-14 days after roast. That can be extended to a month or more if you store your coffee well. Because roasted coffee is so porous and volatile, it is susceptible to light, moisture, and temperature. The two most damaging elements to roasted coffee are light and moisture. I have said it before and I will say it again - don’t put your coffee in the fridge. The moisture of a fridge is just too much for coffee to handle - and if you have it completely sealed, there’s no point putting it in the fridge anyway. Most people will tell you never to put your coffee in the freezer for a similar reason. However, that is a misleading idea. Freezing your coffee can be a fantastic way to add longevity to a roast…IF AND ONLY IF (This is very important) You have your coffee completely sealed from the air before putting it in the freezer, AND you don’t take it in and out of the freezer. In fact, you should only freeze and unfreeze your coffee once.If that sounds inconvenient to your situation, you can get almost as good results simply storing your coffee in an airtight and light tight container. But, if you happen to have an extra bag of some really good coffee that you won’t get to for awhile - put a piece of tape over the seal (the little circle that lets the gasses out of the bag) and stick it in the freezer. When you are ready for it, remove the whole thing and let it sit on the counter until it’s room temperature (and you don't see any moisture on the bag). Again, only take it out once. DO NOT put it back in. Amazon and even Walmart and Target have air tight containers on the cheaper end.
