I’ve done some riding in cold and wet weather lately, and my shoes started to smell mildewy. I found some online mentions of coffee beans as a moisture and odor absorber, so I thought I’d try it. Coffee is known to absorb odors, which is a great reason to never store it in your freezer or fridge.
After one week of testing, this seems to work very well, and I always have extra coffee beans around.
No, I don’t subject my Bookish coffee to such a fate, I drink all of that.
