Storage - Protection/Wrapping
The worst enemy of coffee is air.
The fats in coffee easily go rancid while in touch with air, so it’s essential to store your coffee in airtight conditions.
Most of the packages coffee is sold in are airtight, so the problems begin when you open the bag.
The overall best solution is that the original coffee bag is resealable.
If the coffee bag isn’t airtight it is important to have an airtight container where to store your coffee.
Moving the coffee from one container to another isn’t too smart either, because that aerates the coffee.
