I roast my own too. Get coffee better than the best coffee bars. Much more expensive than regular coffee but much cheaper than the gourmet stuff sold at 'bucks, Peet's etc. it's a fun hobbyI dropped 500$ but it was on 66lb of Green (unroasted) specialty bolivian peaberry beans (includes 62$ shipping)
I roast it and give away aprox half of it. so it lasts about 12-16month usually.
Roasted coffee doesnt age great.. and roasted and ground coffee is even worse.
I think if I wanted to stock up on roasted store bought.. I'd buy about 8 of the big bags of whole bean at costco.. but more than that.. no way.
fyi storing in freezer or fridge isnt great.
the temp change is not good for moisture.. which is bad for coffee.
