For professional baristas, please follow the coffee workshop (Wechat official account cafe_style)
Put the raw beans in the freezer, the water in it will freeze.
Form crystalline structure
I can't keep the water.
So a lot of the smell will run away.
The best way to keep it: bake while it's fresh!
The second best: vacuum the raw beans and then "refrigerate" them.
The third best: raw beans directly vacuum and then "cold storage"
Fourth best: vacuum the raw beans and put them in a cool place
Fifth best: save raw beans in a cool place at room temperature after picking a sealed bag.
--
Sincerely suggest:
No matter how fresh or green the raw beans you buy, you'd better choose not to have "black sheep".
Spoil a pot of careful baking, or infect the raw beans to be preserved.
