Heh... yeah I was watching the video and was mildly interested for a while. I realized he hadn't said much about the sound for a while and looked at the length of the video...
I'd never heard of this Tommy as far as I can remember, and I'm definitely old enough to have heard of him.
Maybe I'll listen to the rest when I want to go to sleep.
I also store mine in plastic container, I actually grind roughly a week to two weeks worth of coffee at a time. The flavor difference after it sits for a while is less noticeable to me than the difference from when I get a new bag of coffee beans.
