How long can I store roasted coffee beans? How long do they retain their qualities? In the coffee store near my home the seller told me that their coffee beans are stored for 1-3 months in their shop. But after purchase I'm also storing them for a few weeks.
I assume you are storing them for a later grinding (likely just before preparing your cups of coffee).

According to some sources 1,2,3, the main point is use it within a week. For more than that, it is preferable to freeze them, and in this condition, for no more than a month.

A brief summary:

For short term use (this week's coffee):


Do not refrigerate your daily supply of coffee (in order to avoid moisture).
Keep them in air-tight glass or ceramic containers, in a dark and cool place.
Keep only the amount of beans you know you will quickly use.


For long term use (no more than a month):


If you have a large amount of beans, wrap them in small (weekly) amounts inside air-tight bags, and freeze them. Once removed from freezer, do not return them.
If you are making coffee in an espresso machine, let them getting room temperature for one day.
