Does the amount of coffee oil have an effect on coffee flower drawing?
The texture of high-quality oil is extremely delicate and even elastic. In order to test the elasticity of the grease, in a general competition, the referee needs to lift the grease 45 degrees. The best grease should be able to reset immediately and cover the surface of the coffee evenly. Most of the taste of milk coffee comes from coffee fat.
In addition to the amount of foam, the degree of fineness, the degree of fusion and the method of making Espresso, the most important point is the oil of coffee.
The state of different oils is actually equivalent to different liquid viscosity. The thicker the liquid, the greater its fluidity.
When drawing flowers, using the same size of water injection, the better the state of Espresso, the higher the viscosity, the greater the fluidity of the liquid, and the clearer the lines of the pattern.
The amount of grease. The thickness of the grease directly affects the contrast of the pattern, the clarity of the lines, and the fusion state of the grease and coffee liquid. Just like the milk foam used in flower drawing, the better the fusion, the thicker the liquid, the greater the fluidity of the liquid, and the pattern lines will be clearer and easier to form. Therefore, when pulling flowers, Italian concentration is the same as milk foam, which needs to be acted as soon as possible after production.
Whether the coffee oil is good or not can tell us whether the coffee beans are fresh. If coffee is used to make coffee as soon as it is roasted out of the pot, the content of nitrogen dioxide in coffee beans is too high, which will lead to the dissipation of coffee oil too fast; if coffee beans are placed for too long, that is, more than 21 days of prime time, coffee oil will become very thin
