I had an eye-opener today. 1 shot of espresso + regular black coffee... why does it wake you up so much? it even made me shaky... it felt good but I can't understand why I even got shaky and really pumped up. I mean regular coffee doesn't do this to me and espresso has less caffeine than regular coffee so why does it wake you up? Anyone with info please post I'll do some research too. 00:55, 13 October 2006 (UTC)

espresso has less caffeine than regular coffee. Sorry, that's incorrect. An espresso is smaller than other coffee servings, but also much more concentrated. A single shot of espresso ends about the same caffeine content as other "standard sized" (noninstant) coffee serves, i.e. a shot of espresso has about the same caffeine content as a typical latte, cappuchino or short black (but a lot less than a "grande"!) In other words, you just doubled your blood's peak caffeine concentration. No wonder you felt shaky. It's also notable that the biological half life of caffeine is highly variable, but typically about 3 to 4 hours in a healthy adult male. Thus, taking a double shot will result in a significantly higher peak concentration compared to having two cups an hour or so apart. -- Securiger 09:14, 19 October 2006 (UTC)

Regional names[edit]

I'm in the PNW (Seattle), and I've heard it called a "sludge cup", but never a "shot in the dark". Is a single menu from a state enough to determine the regional name for something? I suspect it varies by coffee shop at least as much as by region.

Depth charge[edit]

"Depth charge" is generally recognized as the term for a shot glass of whisky, tequila or other liquor dropped into a mug of beer. I doubt that the military would waste a good drinking term on a cup of coffee. (talk) 01:16, 16 November 2009 (UTC)
