Storage of Roasted Beans and grounded coffee

[DirtyDave]

Au contraire, mon frere
Deep freezing will arrest CO2 off gassing (-10 - -20 degs F)
Not practical for the consumer
I find coffee goes flat after 10 days
Just buy enough beans for a week

Despite the science, etc. I would never put my beans near a fridge or freezer simply because of the effects of condensation at room temp. For a typical consumer I would always advise to buy or keep beans in small amounts that can be used in 10-14 days and grind on use. I am also in total agreement with avoiding the effects of light, moisture and air where practical.

Nothing works better to clean a grinder than compressed air.
It gets to all those nooks and crannies that a brush can never fully clean.
A brush (foam or bristle) will always compact into seams and joints.
The resultant remains can (over time) become rancid.
As far as storage goes, cupping (and food science) tells me that vacuum sealed in a freezer has no equal.
For small quantities (and short storage periods) air tight, light proof, room temperature storage should be fine.
It should be a no brainer to grind immediately before brewing.
Buy and consume fresh roasted coffee is the best solution.

my coffee roaster swears by vacuum storage of green beans once they hit the warehouse.
Once the beans are roasted and sufficiently cooled and degassed, they return to the Vacuum.

My only thing with freezers and grinders are the facts, cold attracts condensation and that is bad for burrs/blades. Let the coffee beans come to room temperature before you grind.
