There was a time (before I started this blog) when my ideal coffee was something like this. I would get a big ol’ bag, store my coffee in the freezer, remove it every morning and brew a pot of coffee with it.
One of the first things I “learned” when I stepped into the craft coffee wormhole, was it is never okay to store coffee in the freezer.
More recently, I’ve read several things that heartily support storing coffee beans in the freezer and some things that stick with the old no freezer rule of thumb.
Well. Which is it? Can I store my coffee in the freezer or is it a bad idea to store coffee in the freezer?
Here is what the experts say and of course (it’s my blog after all) my opinion on the matter.
Why You Should Not Store Your Coffee in the Freezer
According to a leading coffee freshness expert, Chahan Yeretzian (who boasts a PhD in chemistry and a pretty impressive resume), you should not be storing your coffee in the freezer.
Yeretzian reports that the coffee aging process is considerably slowed as you cool down the temperature. He also emphasizes that the small benefits you get from impeding the aging process are more than offset by the risk of structural damage to the coffee as well as the possibility of odor contamination and staling by condensation (warm air condenses on cold coffee beans creating moisture, the sworn enemy of coffee freshness).
