Keeping The Coffee Fresh

I'm very grateful for all the gifts of American coffee I've gotten over the years, especially since I no longer go to the states. I must keep them as fresh as possible after opening. I saw that the tabs just didn't do the trick, even though instructions say they should.

As you see, I added a simple clothespin to keep the bag closed.

Even though we have a clothes dryer, I rarely ever use it. I have 20 meters of clotheslines and lots of clothespins.
