The reason why pour-over coffee is always loving is because the process of pour-over coffee requires the action of pouring water, and the way the water is poured creates a small swirl on the surface of the ground coffee.
When the water flows over the ground coffee, due to the change in the speed and direction of the water, a heart shape is formed on the surface of the ground coffee.
This is due to the difference in the power of the water flow and the density of the coffee powder. Therefore, hand-made coffee will always have a heart pattern. This pattern not only increases the ornamental value of the coffee, but also gives a warm and romantic feeling.
The reason is that the white foam on the reverse side is tilted or the hand is unstable when shaken. When the milk is poured, the hand shakes, there is no symmetry in the middle, the stretch point is from which point of the leaf surface to shake the stretch point determines the pattern, and the final position in the cup, the star stretch planning point is generally in the middle of the center point of the page and the distance between the cup arm.
That is because the coffee concentrate extracts more oil, the milk foam is made and dense, and when the barista pulls a uniform speed to the milk, the coffee liquid and the milk will be completely integrated, and the beautiful love will be pulled out
