Okay, every time I mention freezing when I go into Barefoot Coffee roasters I get the "Oh no, don't freeze, that's bad". This time I had a very interesting claim from their head roaster. I had already mentioned how there's been a thorough study on Home-Barista. It seemed like he might have already been aware of it. He then claimed that coffee will absorb flavors from inside the freezer. I mentioned that I have them stored in air tight mason jars and he says it doesn't matter. Now is there something I'm missing here? Air is not passing in or out of these jars as they are in the freezer. I know because when I take it out, they release a bit of pressure that has built up from the gas the beans had given off since being in the freezer.
So how the heck are they absorbing flavors from the freezer?
Here's my very easy taste test. It happens every time for me. I buy 5 bags of beans at a time at Barefoot. Or if you buy 5lbs online in bulk, take 2 lbs, let them naturally degas, and age in one-way valve bags or mason jars. But at the same time put the rest in the freezer immediately. After you've finished the 2lbs, perhaps 1.5 weeks later, go the freezer, pull a mason jar out and defrost. Voila, you should immediately notice that the beans from the freezer are much fresher than the 1.5 week old beans. In fact, they should taste like they are perhaps only aged a few days.
Or perhaps I'm fooling myself and my taste buds don't know what they are missing and I really should be listening to the master roaster and buying fresh all the time. Am I crazy or what?
