How to make a good siphon coffee

How to make a good siphon coffee

1. Siphon coffee is best made without hot water or boiled water, because the more dissolved oxygen in the water (there is almost no dissolved oxygen in hot and boiled water) and the higher the hardness of calcium and magnesium ions in the water (calcium and magnesium ions, not copper, iron, lead and mercury ions), the deeper the metasomatism replacement reaction between water and the good substances in coffee powder, the easier it is to replace the good taste. I added a high calcium and magnesium ion here.

Foaming principle of Italian Coffee pull Milk

Foaming principle of Italian Coffee pull Milk

Use steam to beat milk, make liquid milk into the air, make use of the surface tension of milk protein to form many small foams, so that the volume of liquid milk expands and becomes foam-like milk bubbles. In the process of foaming, lactose is dissolved in milk because of the increase in temperature, and lactose is sealed in milk bubbles by foaming, and the function of milk fat is to make these

The difference between steaming and steaming: without steaming, the extraction is easy to be less than the difference of water injection after hand steaming.

The difference between steaming and steaming: without steaming, the extraction is easy to be less than the difference of water injection after hand steaming.

The difference of steaming or not: without steaming, the extraction is easy to be insufficient. For the coffee powder that has been steamed, the coffee powder will first dissolve some high concentration coffee liquid because it seeps into some hot water, so it is easier to extract some soluble substances of coffee during the second water injection, and some gas in the coffee powder has been discharged during steaming, so it is less likely to be discharged during brewing and extraction.

Technical Identification of Coffee: how to distinguish Coffee-introduction of Cupping Cup Test

After the coffee bean is roasted, the baker will make a simple and effective evaluation of it. This kind of evaluation is called cupping. Cup test is an important link to evaluate the baking quality and taste performance of coffee beans. It allows us to distinguish the nuances of coffee beans when they are roasted, and allows us to deduce the quality of raw coffee beans. The cup square method moves together.
