I am still freezing in the bags they get delivered. Two weeks of rest, seal the one-way valve, and it is good for 3 - 4 months. After 3 months, the coffee is still good; but, we need to grind really finer;
otherwise, It may still pour faster or may channel. Say, 3 months is the max if we store in the coffee bag.
We have an airscape. We don’t use them; it is useless as we open the container at least 4-6 times a day. We are therefore splitting 500g at a time to freeze 100g each in an airtight jam jar. This lasts for 1.5 days for 6 cups. We alway draw a dose from this jar, put the jar back in the freezer and grind straight frozen. The decaf is also stored frozen. The 100g decaf jar will last 3 days for 6 cups.
I haven’t gone down the vac route yet! Thx
