I use Folger's dark roast, either "Gourmet Supreme" or "Black Silk," and keep it in the cupboard in its plastic container. A three-pound can (which has gradually and subtly been reduced to 1-1/2 pounts) costs me $7 and lasts me a month. I can't be bothered with doing anything special to protect it, and I don't have room in the refrigerator. Tastes good to me. Nobody else drinks my coffee, so maybe that's telling me something. I make it a cup at a time in one of those Melitta funnels with the paper filters.

Now, my parents were very particular about their coffee. I think they stored theirs in a metal can in the refrigerator. And they always had to have Chock full o'Nuts coffee, which none of us offspring actually liked. My siblings speculated that nobody born after 1930 could like that brand. I'd drink it, but in limited quantities.

Wikipedia says there are no nuts in the coffee. The store orginally sold nuts, but switched to selling coffee and sandwiches when the Depression made nuts too expensive.

Chock full o'Nuts is that heavenly coffee,
Heavenly coffee, heavenly coffee.
Chock full o'Nuts is that heavenly coffee,
Better coffee Rockefeller's money can't buy.
