When we were doing Civil War Reenactments there were members who put egg shells in their coffee pots to drop the ground to the bottom. I made cotton bags for the grounds and I had a 1930's era hand grinder in my campbox.
Egg in the coffee???? Not for ME!!
When I was one all 4 forums we had a discussion about coffee and tea and how long you can store them. Don't know if anybody else remembers Wifezilla, but she did some Net research and discovered that pre-ground coffee is stale as soon as it is packaged. The most stale you can go is Sanka, and we have a friend who insists it's the only coffee he will drink, but it has to be drunk quickly as soon as the boiling water hits it.
Here is some reading for you:

My DD, who is also a coffeeholic, LOOOOOVVVVEEEESSS to smell the beans in the package, and, since that is the freshest we can buy, it smells like chocolate to me. You can SMELL the caffeine in both coffee beans and really good chocolate.
We came to a consensus that you can keep coffee beans up to 6 months, but only in the freezer.
I keep my beans in 4 jars—I like to buy the big package of either Hills Bros Dark Roast or 8 o’clock Italian Roast (when I can find it!). I started with two quart sized jars of Ovalatine, when they still made the glass jars, because that are dark brown glass. I added two quart canning jars. I can buy fruit in quarts at Aldi with a screw on lid that also fits my canning jars, so I use those lids. I store them in my dark cupboard.
I recently watched Josh Gates (“Expedition Unknown”, The Travel Channel) in Ethiopia served up freshly picked, freshly roasted, freshly ground coffee. SOOOOO JELLY!!!!!

Packaged tea lasts much longer. Btw, you can buy it in bulk.

DD's and I have found that one order lasts us about one year.
