In the world of alcoholic beverages they use private preserve. It's just a bottle of heavy inert gas they top the bottle off with after use. I've heard about people using it in their coffee containers too (e.g. after filling their bean hoppers, when they only open their main container every 3/4 days).

Even marijuana is packed with N20 wash.  Many other products are. My take is the beans go stale ... slightly slower

The correct term is [**nitrogen flushing**](https://www.verywellfit.com/nitrogen-flushing-protects-and-preserves-foods-2505948) and it does appear to increase the stored shelf life of roasted beans. There is a school of thought that using nitrogen (80% of the air we breath) is not a green friendly technique, but it is nevertheless used in other products too.
