Introduction to how to identify a good cup of ESPRESSO coffee and how to use it

Macchiato is more feminine and looks like a miniature version of cappuccino. The biggest difference between them, except that the weight of macchiato is 1/3 of that of cappuccino, macchiato is kung fu coffee with only a layer of milk foam and no milk, so the taste of espresso only stays on the lips, and the taste of espresso will not be diluted by milk. This coffee is the most popular in today's kung fu coffee, because many young cafes like to use this coffee to change styles, such as caramel macchiato, but it has been silently increased several times, and the taste has been reduced a lot.

How to drink:

Because there is a light milk bubble on it, do not stir it with a coffee spoon when drinking it. Even if you want to add sugar, it is best to sprinkle it evenly on the surface of the milk bubble. Drink it directly from an angle, so that the coffee can still be layered in the mouth.

In addition to its unparalleled aroma, consistency and rhyme, Espresso coffee has one of its biggest features: low caffeine. When some people drink Esprsso coffee for the first time, they have the illusion that such strong and pure coffee must have a high caffeine content. In fact, on the contrary, of all the coffee-making methods, coffee is made with the same beans, and the coffee made by the Espresso machine contains the least caffeine. Because the caffeine in coffee is a water-soluble substance, the longer the coffee powder is in contact with water, the more caffeine is dissolved, while the brewing time of Espresso coffee is only more than 20 seconds. When the caffeine is not released, a cup of mellow coffee has already been brewed, so the caffeine content is only 1max, 3mer, 1max, which is generally used in other brewing methods.
