Marginal gains I'm sure, but does it matter if ground coffee is kept in a clear glass jar on the countertop as opposed to in an opaque bag in a dark cupboard?

I would think so, though if you're using ground coffee not sure how much you can save (then again you could argue the other way and if you're using ground coffee you want all the marginal gains you can get). Light degradation is a thing, but also you can't squeeze all the air out of a glass jar the way you can an opaque bag - not sure if that affects rate of oxidation (which is the other thing that damages coffee quality) but can't hurt?

I'd agree with the points that @youClown made, but really the only way is to do a proper test.

Maybe split the bag into bag & jar, and either have one of each each day, or alternate on which you use each day?
