I used to have a Chemex back in the '70's when I lived in Buffalo, but after I moved to Colorado a roommate broke it and I never replaced it. It used to make such good coffee that it would keep for days in the fridge without deteriorating. In the early '80's I stopped drinking coffee and switched to tea—lots of caffeine, but not the jangly feeling I got from coffee.
Eventually I found Market Spice tea and you just need to heat water on the gas stove, have a tea pot and any extra can go in a thermos for later:

If I were to go back to coffee, I'd get a Chemex.
