I understand that it pays to store freshly ground coffee in the freezer. What about instant coffee or cheep prepacked Turkish coffee?
3Your understanding remains an item of debate. The coffee stack would be a better place for the question. And you can't preserve quality that's not there to start with.– EcnerwalNov 5, 2015 at 14:16
See this question on the (non-?)benefits of freezing coffee, over at Coffee SE! We have several questions about storage, instant coffee, etc., that are related and might be helpful.– hoc_ageNov 5, 2015 at 14:31
If you'd like to leave the question here, I'll answer it with some answers and links to Coffee. If you'd like to delete this question and move it to Coffee, we'll answer it there!– hoc_ageNov 5, 2015 at 14:37
I didn't realize there was a coffee stack exchange. I feel OK leaving this here because the question has more to do with food storage than coffee.– Natan YellinNov 6, 2015 at 11:09
In chemistry it is generally accepted that a reaction rate drops in half for each 10 degrees in C drop (about 20 degrees Fahrenheit). So oxygen would still oxidize the freeze dried coffee, but at a slower rate.
It's ok to store freshly grounded coffee or instant coffee in a freezer. Just consider to:
- Pack the coffee in a sealed package or container.
- Avoid keeping coffee with some other high fragrances items such as vanilla essence, rose water etc as these things can affect the main coffee essence.
Here is a source on How to Store coffee that has a clear explanation.
