Red eye is a common name for coffee with
espresso. Other regular names include “shot in the dark”, and “depth charge” –
though, in the United States, this is a federally registered trademark of a
company, Caribou Coffee, so usage is restricted. At the coffeehouse chain
Dunkin’ Donuts, the drink is known as a “turbo”, and is available either hot or
iced. A double shot of espresso in the coffee
may be termed a “black eye”, and a triple shot a “dead eye”.
