Espresso: Commonly misspelled and mispronounced as expresso, the correct spelling and pronunciation is espresso. Espresso is defined as being a concentrated form of coffee extracted by steam under 9 atmospheres of pressure. It is specially roasted and ground for this form of extraction. Once extracted, espresso should have at least 5mm of crema. Ounce for ounce, it is five times the concentration of gravity brewed coffee. Crema: The golden “foam” that tops espresso. If the shotdoes not have any crema, it is technically not espresso,just burnt coffee. Espresso Americano: Oftentimes called “Americano.” It is simply a wonderful espresso with water. Latte: A milk based drink. It is espresso and steamed milk. A latte should have microfoam on top. Cappuccino: A milk based drink. It is espresso and frothed milk. About a third of the drink should be froth. Mocha: A milk based drink. It is espresso, chocolate,and steamed milk, topped with whipped cream. Ivory Mocha: the “white chocolate” version of the mocha. Macchiato: Means “marked” in Italian. A true macchiato (also called espresso macchiato) is simply espresso topped with a dollop of frothed milk or cream. The espresso is “marked” with the froth. A false macchiato (also called a latte/Seattle/Starbucks macchiato) is a milk based drink. The milk is frothed and the espresso shots are poured in last, “marking” the froth with the espresso.
