It is best to use whole milk for coffee drawing. Milk with high fat content can make more dense milk bubbles, and the quality of milk bubbles has a great influence on drawing. Generally, low-fat milk or skim milk will not be chosen. Fat can make milk bubbles more stable. The fat content of whole milk is generally around 3%, and the fat content of skimmed and low-fat milk is below 1.5%.

Milk foam is the product of fine mixing of milk and air. Milk bubbles are made by filling milk with air. The principle is simple, but it is not a simple thing to really make a cup of dense and meticulous milk foam. The most common problem is that too much air enters milk, resulting in too thick and hard milk foam. Such milk bubbles will float on the surface and cannot be fully mixed with coffee, so you can't enjoy the delicate texture of milk bubbles and coffee when drinking.

Introduction of whole milk

The fat content of whole milk is 3.0%, the fat content of semi-skimmed milk is about 1.5%, and the fat content of whole skimmed milk is as low as 0.5%. There is a kind of concentrated milk abroad, the fat content can be as high as 4.0%.

Milk contains many vitamins, among which fat-soluble vitamins A, D, E and K are all hidden in the fat of milk. If the fat in milk is removed, these vitamins will be lost, which is not good for children's growth. Therefore, many countries stipulate that extra vitamins A and D must be added to skim milk. In addition, the reason why milk has a special flavor depends entirely on the volatile components in fat. Without fat, the fragrance will be insufficient and milk will taste tasteless.
