I believe that what attracts your attention in every coffee shop is not only the unique decoration, but also the various espresso machines, which also highlight the different characteristics of each coffee shop!
Although there are various types of machines, the operation methods are very unified. It only takes a few simple steps to bring us a cup of rich and rich coffee! So, when you use it, do you have this question from time to time: Who invented it?
Who invented the espresso machine?
Before the birth of the espresso machine, people had been using Moka pots, pots, and various drip filters to extract coffee, but without exception, the extraction of these coffees required a long wait! There are always people who get tired of waiting, and Mr. Angelo Moriondo of Italy is one of them. So he began to study with great concentration, proposed the concept of coffee machine, and displayed the coffee machine itself at the World Expo held in Italy in 1884!
This machine has two boilers, the primary boiler is used to produce hot water, and the secondary boiler is used to produce steam. When someone needs to extract coffee, the steam produced by the secondary boiler will take the hot water from the main boiler and rush through the coffee powder, and the extraction is completed! Although this machine at this time is not an espresso machine, its appearance has a cross-epochal significance in the world's coffee culture!
Mr. Angelo invented this first-generation coffee machine, but he only applied for a patent for "steam-operated steam equipment for rapid coffee making" and did not put it into commercial production! You know, this was the fastest coffee making equipment at the time!
When the time came to 1901, Milan's technicians improved the first version of the coffee machine so that it could be better used by the masses! Then he applied for a patent for a coffee machine that could be used commercially. In 1905, the fourth year after the application, Desi Decuo of La Pavoni Company bought its patent and improved it by adding a brewing head. At this point, the world's first espresso coffee machine was born!
Because the original coffee machine produced only black coffee, not espresso. Therefore, the first version of the machine can only be said to be the world's first coffee machine, and this one is the world's first espresso coffee machine!
The common coffee machines on the market today are all square and square, but La Pavoni's first-generation espresso machine is not like this. Instead, it looks a bit like a fire hydrant... This coffee machine has a high-temperature brewing head of 140°C and an extraction pressure of 1.5bar, which can extract coffee in 45 seconds!
But if you want to talk about the taste of coffee, it will definitely be inferior to the current coffee. After all, in addition to the backward technology, the beans at that time were not as refined as they are now, so there is no comparison! But its appearance caused the word "espresso" to be included in the Italian dictionary in the early 20th century, annotated as "espresso made using a pressurized machine or filter!"
The reason why the coffee machine we use now can reach 9bar is due to the Milan baristas in 1947! (It turns out that baristas in the past had to know how to make not only coffee but also coffee machines!) It invented the piston manual lever coffee machine, which can have greater air pressure to extract more coffee flavor, and at the same time, it can also have a larger amount of golden oil!
This patent was also acquired by someone else, and the person who acquired it was Faema Company. They used this technology to release the "Faema E61" in 1961 and successfully became famous around the world! Because this coffee machine uses a water pump to increase the pressure to 9bar, and the water temperature and extraction performance are very stable! So as soon as it was released, it caused a phenomenon-level popularity and became famous in one fell swoop. Moreover, many modern semi-automatic coffee machines are researched and upgraded based on it! Therefore, it is not an exaggeration to call it the father of semi-automatic coffee machines!
Gradually, the market for coffee machines is becoming more and more abundant. A variety of novel coffee machines have confused consumers' attention with various advantages. There are even countless small coffee machines for home use, allowing friends to drink a cup of fragrant Italian at home. After saying this, I turned around on Front Street Street and made myself a drink to calm down my craving for a long time~
Front Street, like many of my friends, pursues stable extraction and rich oils when making espresso coffee, so he will choose a specialized formula. Here we will introduce it to you in two types:
Single-origin coffee beans refer to coffee beans produced in a single production area/manor. The flavor is generally relatively clean and clear. If you like floral and fruity aromas, you can buy Front Street Oiran SOE, Front Street Grana Gesha, and Front Street Red Cherry Yirgacheffe SOE. For those who don’t want sour taste, the first choice is Front Street Queen’s Manor SOE and Front Street PWN Golden Mandheling.
Italian blended coffee beans refer to the long-term stability of the flavor by combining coffee beans from different production areas. The flavor is generally mellow and solid. Home users recommend the Front Street Classic Blend and the Front Street Black Cocoa Basic Blend. When ground into powder, it will exude the aroma of cream chocolate and cocoa cookies. The taste is balanced, and the oil is golden yellow and shiny. It is very suitable for friends who open a store or use it at home. In order to add aroma and oiliness, the Front Street Classic Blend also contains a small amount of Robusta, thereby increasing the flavor intensity and allowing novices to easily make espresso with golden oil at home.
The coffee machine used in the Front Street store has a powder bowl with double concentration capacity, and the amount of powder is about 18-20 grams. When Front Street produces latte, 20 grams of coffee powder is used, and a powder-to-liquid extraction ratio of 1:2 is used, that is, 20 grams of coffee powder extracts 40 grams of coffee liquid. The time is related to the flow rate of the coffee powder. Generally, the duration of a single extraction is controlled between 20 and 35 seconds, because within 20 seconds, the coffee tastes easy to be thin, and if it exceeds 35 seconds, it is easy to over-extract and produce a burnt and bitter taste. Most of the concentrates in the front end are in the range of 28 to 30 seconds.
Before extraction, Front Street will prepare these in advance: ceramic coffee cups, milk jugs, and fresh milk. First, dry the powder bowl and align it with the powder connection port of the grinder, turn on the switch, grind out a double amount of coffee powder, place it on the electronic scale and increase or decrease it until the weight reaches 20 grams. Then use a powder spreader to spread the coffee powder, and press the powder press vertically downward to fill the coffee powder cake tightly to ensure more stable coffee extraction.
Then turn on the extraction switch of the coffee machine and let in water for 1 to 2 seconds. The purpose is to moisten the brewing head and take away the coffee grounds stuck on it. Place an electronic scale under the cup that receives the concentration, return the weight to 0, and place it under the brewing head during extraction. Gently snap the handle onto the brewing head and start turning down the extraction switch.
Observe the changes in the extraction liquid. When the electronic scale shows that 40 grams of coffee liquid has been extracted for about 30 seconds, pull down the extraction switch and pour the Espresso into the ceramic coffee cup prepared in advance. After getting the espresso, we can add an appropriate amount of water or fresh milk according to our preference to make a cup of American style or latte.
