Storing beans in a humid country
Freezer, valve bag, or neither.
The enemy
Humidity, heat, and oxygen, in that order. A bag left open in a Taipei kitchen is stale in ten days; the same bag in a sealed jar lasts a month.
Do not refrigerate. The fridge is humid and smells of everything else in it.
In this climate, storage is part of the recipe.
The freezer method
For beans you will not finish in three weeks, freeze them in a sealed bag with the air pushed out. Take out what you need and let it come to room temperature before grinding.
Freeze once. Repeated thawing is worse than leaving them on the shelf.
