Is it appropriate to store unground coffee beans in thoae vacuum storage bags used for food freezing? In this way protection from air, moisture, and heat are ensured. Dividing the beans into daily portions and sealing each portion in a vacuum bag would do, no? :grin:
Squeeze the air out. That's plenty. If you vacuum pack the coffee, you risk turning it stale.

All the canned coffee that is vacuum packed is stale. The canning process removed the aroma. The coffee aroma you get when opening a can is because they inject that flavor back in.

Ideally, you'd want to take the oxygen out of the storage container and replace it with an inert gas like nitrogen. Probably out of reach of the home user.

Open a bag at a time. Squeeze the air out. Use it within a week. If you have more than one open at a time, keep they O2 out. Experts go either way on freezing. But everybody is convinced they are right.

If you have a ton of free time, sure, divide the coffee into daily bags. You may want to try it to see if you can taste the difference. If you can, great. If you can't, then just buy fresh, well packaged coffee, squeeze the air from the packaging and bo through one bag before opening the next.
