EspressoIt originated in Italy and comes from the word Express in Italian, which means "pressed out". Through the pressure of the steam in the espresso machine's boiler, the water passes through the extremely finely ground and manually pressed coffee powder layer, squeezing out a highly concentrated coffee liquid.
Because this method can maintain the coffee oil for a long time, the taste is mellow and thick, and the sourness and bitterness are balanced, it is called a work of art in coffee. In addition, espresso is often used as the basis for other coffee types, such as latte, cappuccino, macchiato, and mocha, all made with espresso as the base.
Espressoflavor and taste characteristics
FrontStreet Coffee believes that the color of a delicious cup of espresso can be seen from the golden crema on the surface of the coffee. First of all, good coffee fat has a mirror-like shine (there is another saying that it is tiger spots, but if the amount of coffee powder is too small and over-extraction will cause white spots), and its thickness should be between 3mm.The taste is usually strong and mellow, with a smooth texture, no graininess, and a perfect aftertaste at the end, with obvious sweetness in the throat and tongue.
The amount of espresso is usually not large, usually 25~35ml, which allows everyone to finish it in two or three sips. In Italy's industrial era, supercharged coffee machines and espresso were invented for speed. Workers could quickly get a cup of coffee and drink it quickly, thereby increasing their motivation to work.
This habit has been preserved to this day. Italians usually go into a coffee shop to have a cup of espresso before going to work in the morning, and drink it on the spot without even having to sit down. Of course, this is just the habit of Italians drinking espresso. When we drink espresso every day, we can feel the charm of espresso (of course, it is recommended to drink it in two or three sips. After all, if it is left for a long time, the taste and flavor will deteriorate).
meaningFormula Condensationdivided into three parts
.
Crema is one of espresso’s most iconic ingredients. What we call the golden to reddish brown foam layer on the surface of espresso is crema. Composed mainly of oil extracted from coffee bean grinds and carbon dioxide. When hot water contacts coffee grinds under the high pressure of a coffee machine, the hot water causes the soluble oils in the coffee to emulsify and then become supersaturated with carbon dioxide, creating many tiny bubbles that form a foam layer.
.
Body has the richest and most delicious taste and aroma of espresso. You will taste the soft part of the coffee. The softness of a cup of espresso is the sum of the tactile properties of roundness, smoothness, viscosity, and fluidity that we perceive.
.
Heart is the layer underneath the body of espresso and is nearly black in color. The core of espresso is the bitterness, which balances the sweetness and aroma of the two layers above.
With the promotion of specialty coffee culture, the quality of coffee beans used to make espresso has been improved. Most specialty coffee beans have more pursuit of the flavor performance of espresso, so we don't have to face it with the heart that espresso must be very bitter.
As long as the barista can understand the coffee beans from a professional perspective, use freshly roasted coffee beans, and adjust and calibrate the extraction parameters of the espresso every day, the espresso can also taste three different flavor expressions in the front, middle and back.
For example, FrontStreet Coffee produces espresso every day, using Front Street Sunflower Warm Yang espresso beans, which are sold in both online and offline stores. This coffee bean is a combination of Ethiopian coffee beans + Honduran coffee beans. After extraction, it has a rich fermentation aroma, vanilla cream, sweet and sour berries, and the flavor of roasted nuts.
How to drink espresso?
Before tasting, we take a sip of ice water to cleanse our mouth and allow our tongue muscles to contract. After the barista serves the espresso, you can stir the coffee with a spoon to make the whole thing more even. Then taste it in three bites. Taste the flavor in the first sip, feel the richness in the second sip, and feel the sweetness and aftertaste of the coffee in the third sip.
When you taste the espresso extracted from "Sunflower Warm Italian Coffee Beans", you can feel the sweet and sour flavor of berries and the aroma of fermented wine in the first sip, the aroma of vanilla cream and smooth taste in the second sip, and the sweetness of caramel and the aftertaste of hazelnut in the third sip.
How to extract espresso?
According to the standards of the Specialty Coffee Association SCA, single powder espresso uses 7-9 grams, double espresso: 14-18 grams of coffee powder extracts 25-35g of coffee liquid in 20-30 seconds, the extraction pressure is 9-10bar, and the water temperature is 90-96°C.
However, different coffee machines, grinders, and the use of coffee beans with different roasting degrees or different origins will cause deviations in the extracted taste. So at this time we need to fine-tune the parameters and correct the taste of the espresso. Generally speaking, the water-to-powder ratio is adjusted first and then the grinding degree. Therefore, each coffee shop will make up and down adjustments according to the coffee beans and equipment used.
Produced by FrontStreet Coffee stores, making a single shot of espresso (1 shot) will use 10-11g of coffee powder to extract 20-25g of coffee liquid, and the extraction time will be about 22 seconds; making a double espresso will use 19-20g of coffee powder to make 35-40g of coffee liquid, and the extraction time will be about 29 seconds.
