A little while ago someone was talking about coffee and storage and such - it wasn't the main topic - and people were saying that coffee beans shouldn't be frozen but, instead, be kept sealed away from light and in an airtight container. Who says that?
We buy bulk beans in those bags with the folding tops. When the top is folded and the metal tabs are in place, it is probable that the container is airtight. We could leave it on a shelf at 65 degrees or so. Would that suffice according to the experts? My son thinks that "airtight" means we have to suckerbag the product, which seems a bit extreme.
So what is the authoritative word?
