There is something to be said for crap coffee. My grandparents used to drink coffee all day, well into the late evening. I wondered how they were ever able to sleep. It turns out the coffee they made was so weak that 12 quarts of it probably had the same caffeine as 12 oz of today's intense artisanal coffees. I had severe insomnia through most of my 20s and I think it was partially due to the fact that I was emulating my grandparent's coffee intake but using "proper" coffee. I still keep up the coffee snob act, but now when I make coffee at home it's 4/5 decaf.
