How do coffee grounds need to be stored? what's the effect of coffee grounds?

When you finish a cup of hand-brewed coffee, you always clean up the coffee grounds, or it's good to store them without cleaning them, so what do you do with the coffee grounds left over from these boutique coffees? Qianjie Coffee has written a number of articles on how to recycle used coffee grounds for uses ranging from skin care products to household reuse to DIY crafts.

These natural residues have many incredible uses if used coffee grounds are properly stored. But you must be careful how you store them, or they may be moldy before you use them.

After brewing coffee with coffee grounds, you need to remove any residual moisture. Put the coffee in a tissue to squeeze out the excess water, and then dry it in the sun for an hour or two (if possible). Coffee grounds should be as dry as possible before storage.

Then, store the coffee grounds in an airtight container in the refrigerator or freezer. It doesn't have to be as airtight as fresh coffee beans or coffee, because it doesn't retain a basis for consumption-just for use at home. The purpose of sealing the container is to avoid the entry of water and the growth of bacteria or mold. For this reason, Mason cans can store used coffee grounds very well.
