Amberale gidday AA, mate it’s certainly not a matter of saving them, other than keeping them as fresh as.
This book is part of the reason: “Dear Coffee Buyer: A Guide to Sourcing Green Coffee” https://g.co/kgs/i6kjEV
In it the author suggests that green beans can stay drinkable for years but at their peak for five months. He writes about how to prolong that freshness and concludes that while freezing them would be ideal, it is probably never going to be commercially viable.
The other part of the reason is that I buy from a cop-op and typically buy 20kg at a time.
So in answer to your question, it’s a combination of the authors observations and buying in bulk and voila … enter the freezer.
I like being able to open the vertical freezer most weeks and choose from Kenyan to Costa Rican or Ethiopian or beans from Yemen, Guatemala.
