If you are going to store coffee store beans not ground coffee. Actual coffee growers tell you flavor and longer life is in storing the beans. I don’t drink coffee but store it for other family members as whole beans in quart mylar bags with oxygen an absorber.
Green beans are even better …if you know how to roast them. DH has some stored in different ways. I can’t stand the stuff myself. DH wasn’t paying attention [what else is new..lol ] and bought MOCHA chocolate ice cream. Ice cream is just about my favorite of ANYthing….but not that stuff. Poor DH had to finish it all himself. Hmph!
