Today, you will find many kinds of espresso machines in the market each with their own set of advantages and disadvantages which you can easily come across in many espresso machine reviews. Mentioned below are a list of steps one should follow in order to understand and efficiently use an espresso machine.
A basic shot of espresso coffee as claimed by many espresso machine reviews is made by passing roughly 1.5 ounces of hot water through coffee beans. However, the color and taste of this shot of espresso varies individual to individual and depends on many other factors like water temperature and finesse of the pack of coffee beans.
Simple espresso machines contain a funnel shaped metal that extends downwards to where the brewed coffee would get collected into a cup. This brew point is known as a group head. Home based espresso machines have one group head while other commercial based ones have more than one group heads which can simultaneously spout 2 to 3 cups of freshly brewed coffee.
The most commonly used steam driven espresso machine employs the use of steam to force the hot water through the finely ground coffee beans. The water that is poured through the top is closed tightly into the machine before putting on the fire to heat up. Once it is heated up, the pressure builds- the more heated the more pressure created. This pressure is then sent through the tube down through the espresso beans. The outcome is a perfectly brewed coffee cup. On the other hand, if you are looking forward to a cappuccino, the steam plunger can also be used to froth milk before being put in the freshly brewed coffee.
How an espresso machine works is quite simple and easy since most of the espresso machines employ the basics of a steam driven one. However, it is recommended that you should thoroughly go over the instruction manual that comes with every espresso machine.
