An espresso is very concentrated, and comes in a very small cup. The flavors are stronger than coffee because of the finely grated beans and the high pressure used during brewing. Espresso is made by forcing very hot (not boiling) water through finely ground coffee. If the water is too hot, the espresso will be too bitter. There are several differences between espresso and coffee. For example, espresso is thicker. Also, there are more dissolved solids in espresso than there are in coffee. Selecting the blend is important when making espresso drinks, as it is for any kind of coffee drinks. The factors to concentrate on are sweetness, aromatics and smoothness. Espresso is an amazing drink that can add flavor to many other drinks. When mixed with milk, hot water, sugar or chocolate, espresso can be turned into lattes, mochas, cappuccino and macchiati.
