Espresso Maker - A Must-Have For Home Baristas
Espresso is a robust dark-brown beverage made by forcing hot water through tightly packed, finely ground coffee. It is the basis for many popular coffee drinks at the cafe.
A skilled barista (also known as an espresso maker) controls a number of factors to make a perfect cup of espresso. This includes the temperature of the water, the pressure of it and how tightly the coffee is packed.
Origins
The espresso maker is a machine that pushes small amounts of near boiling water under high pressure through coffee beans that have been finely ground. The resulting beverage is much stronger than drip coffee machine espresso, is more concentrated, and served in smaller cups. This is a great choice for those who want an intense cup of coffee but need it fast!
The first espresso machines were created in the 19th century. The coffee industry was a huge industry, but the process of making it took too long. People were impatient, and wanted a quick cup of coffee!
Angelo Moriondo of Turin patented one of the first coffee machines in 1884. The machine's name was "New steam machinery, for the economical and instantaneous preparation of coffee beverages. Method A." Moriondo."
The Milanese manufacturers Luigi Bezzerra and Desiderio Pavoni adapted and improved on this machine. They included the portafilter, multiple brewheads and other innovations that are still used in espresso machines today. The machine was dubbed the Ideale and it impressed the crowds at the 1906 Milan Fair. Nine out of 10 Italian homes have Moka Pots. Moka Pot.
Variations
Espresso's flavor is more intense than coffee, and it works well with milk and other ingredients to create café favorites such as cappuccinos or lattes. Its bold flavor also shines in recipes for baked goods and even marinades.
There are four kinds of espresso makers including manual levers, semi-automatic, automatic, and super-automatic machines. Each model has a unique method of creating pressure for extracting the espresso.
A manual lever machine utilizes an electric piston that pushes water through the ground. It's a great compromise between human control and mechanized precision. It's still necessary to grind, tamp and pull the shot by hand however, you have a lot more control over water temperature and pressure.
Moka pots, another manual espresso maker, work like modern espresso machines powered by pumps. In an airtight, sealed tank, boiling water creates steam. This steam is transferred into a basket of ground coffee, then through an iron filter into the top cup. They're less expensive than full-sized espresso machine, but they're only able to reach up to 1-1.5 bars of pressure, which is lower than the ideal for brewing espresso.
Ingredients
Espresso makers can aid baristas in the home to make popular coffee drinks like lattes and cappuccinos. You can also add flavored extracts or syrups to espresso shots to create an indulgence drink like the espresso martini.
For a perfect cup of espresso you'll need premium beans, fresh milk and sugar. Make sure you choose beans specifically marked for espresso, and then grind them with precision to ensure even extraction. You can experiment with various roasts to find the one you like the best.
Also, you'll need an espresso grinder, which grinds the beans into a uniform texture. The espresso machine comes with a portafilter, which holds the grounds, and a tamper. This is used to seal the coffee.
Finally, you'll need an espresso cup as well as a steamer or an ice maker to create the silky aerated, aerated milk that's typical of professional espresso maker drinks. Some machines have steam wands that make the process easier. You'll also need to regularly clean the machine, which involves running a solution of water and vinegar through the system.
Techniques
Espresso brewing is based on creating pressure to quickly extract the intense flavor from finely ground dark-roasted coffee packed tightly into a 'puck. This method of brewing creates the strong coffee shot referred to as espresso. If done correctly espresso has a rich crema (or dense foam) over the top.
Unlike the Moka Express that uses heat to purify water through coarsely ground coffee, most espresso makers make use of highly pressurized water pushed through small grounds under high heat. This creates an espresso-like drink which can be mixed with water or milk to make other beverages like lattes and cappuccinos.
While the Moka Express is a simple, low-cost appliance, other Retro espresso maker machines can be complex expensive, and offer many drinks to choose from. The most well-known machines, however, are Italian-designed levers that use spring-loaded arms for dispense hot water from a cylinder into the portafilter. A barista who uses on such machines can control the timing of pulling the shot, and adjust factors like grind size and water temperature on a shot-by-shot basis to get the best results. These machines were instrumental in bringing espresso machines for home into greater prominence throughout Italy and Europe.
Equipment
A top espresso maker needs to be able to extract soluble as well as insoluble solids from tightly packed, finely ground coffee. This process is assisted by pressure and controlled variables like temperature and grind size. Then there's the flavor, which is dependent on various factors, including the beans and the method in which they're handled and brewed.
There are various kinds of espresso machines, but the semiautomatic is the most popular. It makes use of an electric pump to force the water through the grounds. It also permits the user to do the grinding and tamping. These machines are typically the most affordable, but they're not as consistent as a spring piston or other manual designs.
The lever models that are more expensive feature the calibrated cylinder which does all the work. They're more flexible than a spring piston machine however, they require some experience to use correctly. These machines require a lot more maintenance. You must heat the portafilter and then take apart the portafilter and the piston each time.
