In recent years, an iced milk coffee called Dirty has become more and more popular. The warm, mellow espresso on the top and the sweet and delicious iced milk blend together to form a unique taste of hot and cold alternation. And the good looks on the camera are even more divided, and many stores add it to the fixed menu.

What is Dirty coffee?

Dirty means dirty and dirty in English, so Dirty coffee is also translated as dirty coffee. Dirty's idea stems from the "dirty food" craze that started in 2019, when Dirty Coffee was not what we see today. At that time, use milk foam or cream to make a spill effect, and then add cocoa powder, chopped nuts and so on to create a "dirty" feeling, just like the popular dirty bags at that time.

Today's Dirty puts more emphasis on the taste of coffee, topping white milk with a double dark brown espresso. The gravity coffee liquid is used to infiltrate downward, giving people a visual effect of "tarnishing" the milk. It is said that Dirty coffee originated from a Japanese coffee shop. There is no clear statement about who invented Dirty, and there is no unified production standard, so the Dirty produced by each coffee shop may be different.

How do you make Dirty coffee?

Although the only raw materials for making Dirty are espresso and milk, Qianjie believes that it takes some skill to achieve the perfect layering and hot and cold taste of milk coffee.

As Dirty coffee mainly emphasizes the preservation of the oil of espresso liquid, as well as the visual effect of layering and gradual change, it can not be made with ice, which can easily dilute the overall concentration of coffee. And the protein and milk fat content of milk must be high, and the milk temperature must be cold enough for rich oil to float on the top. So Qianjie suggests using frozen milk or purified milk when making Dirty (ice blog).

Since no extra ice is added to the Dirty, in addition to the milk itself being refrigerated, the glass itself should be kept moderately cold so that the milk will not be taken over by the glass when it is poured into the glass. Qianjie needs to remind everyone that when you buy a glass, you must see whether the cup is heat-resistant or not, in case it bursts during freezing or when espresso is poured.

To ensure the full-bodied taste, the cup size of Dirty coffee is smaller than that of iced latte. Generally, the cup size of Dirty coffee is between 180-220ml and that of iced latte between 280-320ml. When making Dirty coffee in front of the street, first take a cup that is chilled in advance and pour in the fresh milk of 150ml. Then use 20 grams of coffee powder, extract 36 grams of coffee liquid, put the iced milk directly under the bottomless handle, and let the coffee liquid fall on the surface. Pay attention to the water column can not be too high, easy to rush directly into the milk below, it will not be able to form a "dirty" feeling.

How would you like your Dirty coffee?

What Dirty coffee drinks is its layered feeling, so after the coffee is made, it does not need to be stirred evenly, nor does it need a straw, we can just taste it. The taste of Dirty mainly depends on the coffee beans used. Qianjie stores use their own roasted "sunflower sunflower mix", which is a combination of 70% Honduran sherry coffee and 30% Yejia sherry sun-tanned cherry coffee. Shirley's whisky, vanilla and cream flavors with tropical fruits and fermented red cherries make the coffee in the cup rich in aroma and soft in taste.

The first sip of Dirty coffee can get a strong aroma of coffee, showing the flavor of whisky, vanilla and berries. At the beginning of the second mouthful, with the fusion of frozen milk, you can feel the taste of cocoa and cream. After drinking, there is a rich sweetness of espresso and milk in the mouth.
