Maxwell House, and, I suspect, other brands, sell coffee bags,similar to tea bags, in both regular and decaffeinated. The individual coffee bags are sealed in foil, not paper like many tea bags. The smell and taste is excellent after months of storage: the foil does an excellent job keeping the product fresh. I occasionally drink decaff. at home; the jar version of decaff. get pretty stale by the time I'm half-way through. Not so with the foil-wrapped coffee bags.
The bags make a compact/easily rotated/satisfying/inexpensive addition to a car/snowmobile bag or BOB for those who need/want the caffeine/smell/taste.
Ditto for individual foil-wrapped servings of hot chocolate (Swiss Miss, and probably others).
Ditto for foil-wrapped creamer packs for the coffee (Cremora).
Ditto for some of the more expensive foil-wrapped tea bags (I can't think of any tea brands that come wrapped in foil at the moment).
