George Howell has some good info on freezing greens on his website. All my greens get vacuum sealed in either jars or bags & stored in my storage freezer.

I have been doing this and found that beans seem to last a bit longer but I still try to use them withing 2 years.

They'll last much longer then 2 years vac sealed & frozen.

I've got a variety of greens in my freezer dating from 2011-2017 at the moment. Picked up 25 lbs of SM's Moka Kadir in 2011 & still have 5-6 lbs left. I've yet to notice any deterioration in any of my older greens. They still smell like fresh greens when I open the bag or jar, roast up normally & produce great shots if I don't screw up the roast.

My experience is that beans in a vac sealed bag and stored at 4* centigrade in a refrigerator last for years. I have been reluctant to place them in a freezer as freezing cells alters cellular structure. As others have good experience with freezing I trust that method too. If you don't have extra freezer space the refrigerator works too. The key is a good vacuum sealer.

The cell structure thing makes sense.

I figure that if George Howell hasn't noticed any issues with freezing greens there probably aren't any. He stores his vac sealed greens in industrial storage freezers at around -20*F.
