Espresso Machine Coffee Maker – Popular FAQs

There are several different types of espresso machine coffee makers. Espresso is a type of Italian coffee that is very strong and concentrated when compared to other typically American coffee. It is made by forcing water at around 90 degrees C through about 10 grams of very finely ground coffee. The pressure compression is about 900 kPa. It is this combination of temperature, grind and pressure that produce the espresso.

It should take about 20 to 25 seconds to make an espresso. Espresso machines may also have a steam wand in order to make a latte or cappuccino. A steam driven machine uses steam pressure to make the espresso. This type of machine doesn’t have any moving parts and is a lower priced model.

The first ever piston espresso machine was made by Gaggia in 1945. A lever is used to send pressurized hot water through the ground coffee. This is also known as pulling a shot. The piston machine can use a spring pistons or a manual piston. The manual piston machine the barista actually pushes the water through the coffee and the spring piston a barista makes sure a spring is at the correct tension.

Pump driven machines are founding espresso bars and uses a motor pump to force the water through the coffee grounds. Many times the most expensive machines can even be connected directly to your plumbing. You can also find home espresso pump machines that have separate chambers. One chamber is for the hot water, and then this goes to a heat exchanged before it is pushed through the coffee.

There are also variations on these traditional espresso coffee makers that include a semi-automatic that uses a manual pump, the automatic uses a flow meter and electric pump, the super automatic will automatically grind the coffee, tamp, extract the coffee, add water and make the espresso.
