Espresso Machines
Created by Alan on 19 Feb 2009 | Tagged as: Uncategorized
Espresso Machines are devices that pump hot water through finely-ground coffee at a high pressure. The result is a highly concentrated coffee that is brewed very quickly. A single 1 oz "shot" of espresso contains about 100mg of caffeine, which is roughly equivalent to a 6oz cup of drip coffee.
Espresso is traditionally enjoyed with sugar and a small portion of milk or cream, however, in more recent times, drinks made from espresso such as lattes, cappuccinos and mochas are very popular.
However you like your espresso, you need an espresso machine to do it. There are three main types of espresso machines:
Manual Espresso Machines
Manual espresso machines require the barista to pull a lever which pumps the water through the coffee. These machines have a retro appeal to them, and in the hands of an experienced barista, can produce beautiful espresso. They are not very common anymore, making them collector's items.
Semi-Automatic Espresso Machines
Semi-Automatic espresso machines have a built in pump which is usually activated by a button or switch. The barista does not have to manually pump the hot water through the coffee, but still must grind the coffee correctly, tamp it just right, and time the shot. Steaming milk must also be performed, so semi-automatic machines still require a bit of skill to produce the tastiest espresso. However, with a little practice anyone can master the semi-automatic espresso machine.
Automatic Espresso Machines
Automatic espresso machines are fairly modern inventions that take all of the guesswork and effort out of the espresso brewing process. Many automatic machines will automatically grind the coffee beans (many also allow you to adjust the grind), dose and tamp the coffee, pull the shot, and many have attachments that will steam milk perfectly. Just push a few buttons, and you'll be enjoying a tasty espresso drink quickly. With an automatic espresso machine in your home, you'll never need to buy another latte.
