After drinking the Archived Coffee at Lackland AFB, brewed by the way in 1947 and just added to black is the only way.. Well except for Cafe con Leche, Puerto Rican Coffee That stuff makes Expresso look like water
For me, it depends on who makes the coffee. If I am visiting my BIL I drink it black. However, in my house I do add some half and half. My wife loves Starbucks French Roast and we make it VERY strong. Just a bit of cream takes away the bitter taste. When I make the coffee for myself, I don't add anything. Plus, with expresso I like it without anything added.
My first year of college my mom came to visit and we went for breakfast at a diner right by campus. I was all proud to show her that I wasn't a kid anymore. And I was especially proud to show her that I was now a coffee drinker! So I ordered a cup with breakfast.
My coffee arrives and I immediately grab the cream and sugar and start dumping it into my cup of coffee (at that time I had to make it taste like coffee ice cream). So my mom looks at me with distaste and asks, "What. Are you doing??"
"I like it with cream and sugar." I said.
So she barks at me, "Don't do that." "If you're going to drink coffee drink it like a man. Drink it black."
The wind was immediately taken out of my sails. But I tell you this. I have had my coffee black ever since that encounter.
Sounds like these researchers have spent too long drinking Starbucks french roast or gasoline station swill. A psychopath may like bitter black coffee like a homeless drunkard loves cheap wine, but that does not mean that everyone who likes Two Buck Chuck is a researcher.
I've been doing french press lately and like to drink mine with some frothed skim milk. Never any sugar. When I get an espresso, I typically put one sugar in there. Nothing else. But make no mistake. I'm still crazy. At least that's what my wife is always saying to me.
