Coffee
There is the idea that coffee beans or ground coffee are best preserved in the fridge. Although it is true that you need a cool place and if possible airtight, but again extreme temperatures, humidity and sudden changes in temperature are enemies of coffee and its aroma.
Exactly the same goes for tea, by the way.
Bread
Do you keep bread in the fridge? Please don’t, because the same thing happens with the bread. It may last longer without getting bad but the humidity and the cold will cause it to break down faster.
