The common sense of making espresso that determines the quality of materials

1. Italian coffee beans

There are many kinds of Italian coffee beans on the market. Italian coffee beans are blended in the way of comprehensive beans because of their rich and multi-layered taste and taste. And Italian coffee is also divided into southern Italian flavor coffee and northern Italian flavor coffee, the northern Italian beans are roasted in medium and shallow way, due to the selection of beans, the caffeine content is less, the taste is rich and bright with a little sour fruit flavor, and the aroma tends to flower or peel aroma. Nanyi coffee beans are deep-roasted because of their high caffeine, full-bodied flavor and caramel-like sweet finish, with a fruity or cocoa aroma.

Why is there such a difference between the North and the South? Because Italy is a long country, there is a great difference in climate between the north and the south. Because the climate is cold and the taste of the diet is relatively light in the north, most of the coffee beans are roasted in the medium and shallow way, while those in the south are mostly roasted because of the hot climate. So the taste of the diet is heavier, and naturally the roasting of coffee beans tends to be heavy. In addition, because of the gap between the rich and the poor in North and South Italy, when people in northern Italy choose coffee beans, the proportion of Arabica beans is higher, because the content of caffeine will be lower, and the content of coffee oil will be relatively less. And people in southern Italy will add Robusta beans when matching beans, so that the content of caffeine will be more than the flavor of Northern Italy, so the content of coffee oil will be more abundant.

two。 milk

Generally speaking, whole milk is more appropriate when choosing milk, and milk fat above 3% is more suitable, while the taste, organization and composition of various brands are slightly different, and they are paired with coffee beans according to their personal preferences. If Italian coffee beans choose southern Italian flavor, then you can choose milk flavor when choosing milk, but if you want to emphasize the flavor of coffee You can also choose milk with ordinary milk flavor. If Italian coffee beans choose northern Italian flavor, you can choose medium milk flavor when choosing milk, so that the flavor of coffee will not be changed by milk, but if you want to put special emphasis on the flavor of milk, you can also choose milk with strong milk flavor, according to your own needs and preferences.

3. Other materials include cocoa powder, cinnamon powder, chocolate sauce, caramel sauce and so on.

Coffee cups and flowers

The shape of the coffee cup is also closely related to the way the flower is drawn. Generally speaking, the shape of the cup body is divided into two categories, one is the tall cup, the other is the short cup. Tall cups are longer and stronger. But if the amount of milk foam is not enough, it will not be enough when you start to draw a flower pattern, and you will not be able to draw a beautiful pattern. On the other hand, if the amount of milk foam is very rich, the coffee pattern will be very good, but the skill will also be relatively improved. Because the dwarf cup has less capacity and shallow depth, the action of drawing flowers should be very fast, and it will be more difficult to make advanced patterns and difficult patterns, but the pattern will be easier to appear when brewing coffee.

In addition, the shape of the bottom of the cup is also very important, which can be roughly divided into two types: the arc bottom and the square bottom. the fusion uniformity of the arc bottom will be better than that of the square bottom. the reason for this is that the surface area of the square bottom is larger and the height of espresso will be reduced, so it is easier to overturn during fusion, resulting in the breaking of the cream on the surface. And the shape of the square bottom right angle will also make the tumbling way not smooth during the fusion, and the fusion is also easy to produce uneven situation, so that the taste is not uniform, and even the diameter of the cup mouth will have a different effect. The larger the diameter of the cup mouth, the larger and brighter the pattern, but because the larger the diameter is, the larger the surface area is, and the thickness of the milk bubble will be affected and reduced. However, if the diameter of the cup mouth is too small, it will be more difficult to pull flowers.

Finally, when choosing a cup, you should choose a cup with a better heat preservation effect, so as to maintain the temperature of the coffee.
