Shot in the dark or Red-eye: Both of these are names for the same drink, a cup of coffee with a shot (or more) of espresso. This will really give you a caffeine boost. This is also sometimes called a Hammerhead.
Macchiato: Despites what the competition has done to this word, hardcore coffee fans know that the drink is really a shot of espresso with a dollop of frothy milk or cream.
Cafe Au Lait: For this drink we take half a cupful of brewed coffee and top it off with steamed milk. It is also known as a Misto.
Why Bother: A clever name for a non-fat decaf latte. It can also be adapted to flavored drinks - for example, a Vanilla Why Bother would have sugar-free vanilla syrup.
Affogatto: Technically, this is a hot espresso shot poured over ice cream, but in our case we'll pour that hot shot onto a freeze and call it good. Real good.
Breve: Instead of milk, we use steamed half and half to make a latte.
Tea Latte: Instead of hot water to brew your tea, try using steamed milk instead.
London Fog: A variation of the tea latte, this drink is made with steamed Chai and Earl Grey tea.
Of course this is only a short list of some options. Espresso is an ingredient that begs for creativity, and we enjoy helping you express yours.
