Very good morning, happy Saturday.
I keep my coffee in containers that guarantee its flavor and smell. These are ideal, plus the rubber on the lid allows for vacuum sealing and this detail allows the coffee to last for weeks without losing its properties.

Sometimes when for some reason I buy a lot of ground coffee, I keep half of it here and the rest I seal very well and freeze. The cold also maintains the flavor and smell, as long as it is very well closed.
Greetings...
