Coffee
It is never recommended to store coffee or coffee beans in a refrigerator or a frozen state. This is something that all experts, including those at Starbucks, agree on. If you store your coffee in a refrigerator or freezer that is much too humid, the flavour and scent of your coffee will be compromised.
Keeping coffee in the freezer should only be considered if you purchased it in bulk and won’t be using it right away, or if you don’t drink coffee every day and want to have some on hand for guests. Just don’t do it, your coffee will be wasted, so consume it in a good state and store under reasonable temperatures.
