I’ve had a vacuum sealer for years but I moved away from that due to my concern with the plastics the food is sealed in not being recyclable. I see now that recyclable ones are available I’ll start using it again… for food.
As for coffee… Now I know I’m being a bit of a dunce here (yes I know, what’s new) but Tompoland are you making the tiny bags to hold just 18g of beans, cutting to size from a roll, sealing edges to make a pocket ready to take the beans? Because I’ve not seen any that small and if so, it must take you ages because you’d need 55 bags for every kilo of beans. Then once opened you just throw them away?… sorry recycle them and start all over again?
I usually buy aboout 4 × 250g bags of different types of beans at a time because I like to try different ones. Even if I only have 2 cups a day at 18g per cup that will still only take me about 3 and a half weeks to get through and more often than not is is less, as my other half likes a cup too. I guess if like you I was roasting a lot then it might make sense, but for the likes of me it seems a lot of work and whether or not my taste buds could tell the difference between vacuum sealing and just freezing for a couple of weeks is debateable.
