Coffee goes stale from air, heat, light and moisture, and Penang has plenty of two of those.
Do
Keep beans in their bag, pressed flat and sealed, or in an airtight tin
Store them in a cupboard away from the stove
Buy what you will drink in two to three weeks
Don’t
Keep them in the fridge: they pick up moisture and smells every time you open it
Grind more than you need for the next cup
Our bags have a one-way valve that lets gas out without letting air in, so they are the best place for the beans.
