For me part 1 is using 1-way valves after roasting and for resting the roast.
Part 2 is once I open a bag then Airscape, I take the point about opening and closing any container so in my case the smallest Airscape which I think is 320g or something like that, the shortest one basically and only fill it a third. That coffee goes within a couple of days then repeat from the 1-way valve bag.
Historically I tried vacuum bags but did not want to freeze beans or go to heat sealing them. If I did the latter I would probably find small 150g to 200g bags that have enough room to cut the seal then re-seal as needed but as I get older I can’t be ar5ed to go to this effort.
