What is the name of coffee called dirty?

The reason why coffee is called dirty is that when espresso is slowly poured into the upper layer of milk, the coffee liquid slowly penetrates into the milk, forming natural color layers. From the outside, the pure white milk around the cup seems to be colored with caramel color. It looks like the white color has been stained with "pigment", so it is named Dirty coffee.

Dirty has very high requirements for espresso. Basically, it requires the espresso to be rich and rich in oil, so that the overall quality of the espresso can be made "light" and not easy to sink.

Purchasing Guide

No matter what kind of coffee it is, freshness is an important factor affecting the quality. When purchasing, grab one or two coffee beans and chew them in your mouth. If there is a crisp sound, it means that the coffee beans are not damp, and the coffee beans that have a fragrant aroma on your lips and teeth are of the highest quality. However, it is best to pinch them with your hands to feel whether they are solid. , never buy empty coffee shells.

Freshly roasted coffee beans are not suitable for drinking immediately. Generally speaking, the best drinking period for coffee is one week after roasting, when the coffee is the freshest and has the best aroma and taste.
