I am to Coffee what Brewmonkey is to Beer: A snob.
I spend way too much time and energy (and money) on Coffee. Though I am not one of those people who will spend $7 on a "Double Tall Decaf Skinney Latte with X flavor"... I hate those fuckers.
But seriously, if you're walking around out here with a cup of Millstones or Folgers or something, people will look at you like your face is on fire, and a monkey is having sex with your ear.
I have 4lbs of Kona, 2lbs of Kuai, and assorted other roasts in the garage freezer. I start out with a cup of whatever is in the pot when I wake up (Wife makes the first pot, and is gone to work by the time I wake up) which is probably Kona or Kuai, which I drink black, then later in the morning I'll make what is essentially 5 shots of espresso, which I'll mix with about a half cup of milk per shot. I'll drink off of that for the rest of the day (no, not all at once).
This is far better than my former practice from my infantry days in the field: Pour 2 bags of MRE Coffee into mouth, wash down with water from canteen.
I believe that in order to be selected for E-6 in the Marine Corps, you must be able to consume an entire vat can of coffee per day. Twice that for selection to 1st Sgt. I've never actually SEEN it written in any of the promotion criteria listed in the ALMARs, but I know it's in there somewhere!
