I've been wondering if something sitting on top of the beans in the hopper (eg a bag of rice) would stop new oxygen reaching the beans as their level drops. Ideally, the hopper would be cylindrical and the object a simple disk, but mine is the usual conical shape. Or am I over-thinking this?

vacuum? What. No it just limits where new air can get in. Fresh air will always get in yes.

I have a small jar that keeps about a weeks worth out of the bag, and then I grind dose daily.
