Coffee Trivia

Espresso is both a coffee beverage and a brewing method that originated in Italy. When making an espresso, a small amount of nearly boiling water under pressure forces through finely-ground coffee beans. It has more caffeine per unit volume than most coffee beverages. Its smaller serving size will take three shots to equal a mug of standard brewed coffee.
