In Italian,espressoIt means "quickly made for you". The barista takes one minute to make a cup of espresso. After the customer gets the coffee, he drinks it in three sips. It is made and drank quickly, so people are accustomed to drinking coffee standing up and leaving immediately after drinking. If you want to sit down and enjoy your meal, you may have to pay more for service.

Of course, if you order a cup of espresso in a domestic cafe, you can sit down and taste it, but it is also recommended that you finish it in a few mouthfuls.


whyEspressoWant to drink it as soon as possible?


The most "addictive" thing about drinking espresso is not only its strong taste and texture, which can make people wake up in an instant, but also the smooth and delicate oil Crema that makes the coffee taste smooth.

But the grease here is not just grease, most of it is foam formed by carbon dioxide. When the espresso falls into the cup, the carbon dioxide returns to the air, so the foam dissipates quickly, which is why the espresso needs to be drunk as quickly as possible.



How to extract rich espresso coffee?


Only freshly roasted and freshly groundmedium dark roast coffeeOnly beans can extract the attractive golden yellow oil. Because the oil is in a sealed and pressurized environment, the coffee bean oil and carbon dioxide are fused with each other and then squeezed out by the water, forming a oil foam with a delicate and smooth taste.


The longer the roasting time of coffee beans, the more carbon dioxide will be produced and stored in the coffee beans, which will also allow the coffee to form more mellow substances. If lightly roasted coffee beans are used to extract espresso coffee using a pressurized method, the acidity of the coffee beans itself will increase due to the increased concentration, resulting in a sour taste, and the taste will also become thin due to the lack of mellow substances.

At the same time, the most important thing for espresso is that the quality and flavor can be stable for a long time. Therefore, FrontStreet Coffee recommends extracting espresso and choosing comprehensive coffee beans specially blended for espresso.


Single-origin (single-origin) coffee beans are used as concentrates. They are affected by climate and terroir every year, as well as the passage of time after roasting, so the flavor performance is not stable. When blending coffee beans, the store understands the characteristics of coffee beans from different production areas, and blends them in a careless proportion based on the advantages and disadvantages of coffee flavors in different production areas to balance the flavor of the coffee.

The difference between one shot and double shot: One shot refers to a single shot of espresso, while a double shot refers to a double shot of espresso. The amount of powder used and the extraction time of different shots of espresso will also be different.
