What is the definition and concept powder-to-water ratio of SCAA's gold cup theory?
The proportion of SCAA refined cup coffee defined by the Gold Cup Fine Coffee Association of the United States and the European Fine Coffee Association of scae, the extraction rate of coffee must be about 20%, while the TDS (concentration ratio) is about 1.1% to 1.3%. For Drip Filter dripping and brewing, how to extract the best coffee flavor, the controlling factors are nothing more than the changes of the extract of coffee powder and the concentration in a cup of coffee.

About the storage of coffee beans
The ideal way to buy and make coffee is to buy a lot of raw coffee, bake it yourself, and grind it before you prepare it. But most people like to buy roasted coffee beans, and they probably buy more than we use for several days. Water is the enemy of storing coffee. Coffee oil is water soluble. It makes coffee more flavored, while moist conditions can corrupt coffee oil.

The storage of coffee beans directly affects the quality of coffee beans. Water is the enemy of coffee storage.
Second, the storage of coffee beans 1. Factors affecting the quality of coffee beans Water is the enemy of coffee storage. Coffee oil is water-soluble, it makes coffee more flavor, and moist environment can spoil coffee oil. Another enemy of coffee beans is oxygen, which oxidizes volatile odors. That's why coffee beans are ground before making coffee. When coffee beans are ground

How to determine the thickness of coffee beans?
When grinding beans, the size of the powder depends on the way it is cooked. Generally speaking, the shorter the cooking time, the finer the ground powder; the longer the cooking time, the thicker the ground powder. In terms of actual cooking, the Espresso machine takes a very short time to make coffee, so the coffee powder is the finest, and the coffee powder is as fine as flour; it is cooked in a "plug" way.

Basic chemical reactions that occur during coffee roasting
Many thermal and chemical reactions take place during baking: decarbonation, dehydration of quinic acid, fragmentation, isomerization, polymerization, and complex sugar reactions (caramelization). The main thermally reactive components are monosaccharides and sucrose, chlorogenic acid, displaced amino acids, and trigonelline amide. Both aravinone and calactose in polysaccharides are transferred, and basic sulfurization contains hydroxyamino acids.

Before combing the conclusion, the spectators who need to come in should first understand the following three concepts. Emulsification is a very old concept used in espresso, but only one result of emulsification is given. in fact, oil and some fat-soluble, insoluble substances are extracted under high pressure and used as a surface agent by proteins and other strange things in coffee, making these lipids suspended in

Teach you to judge a good Espresso
People like to drink coffee because it releases flavor and aroma when it is brewed. The sources of flavor in coffee are mostly water-soluble, such as caffeine, protein, sugar and so on, while the sources of aroma are mostly insoluble, such as coffee oil. The volatile aroma of coffee oil is found in roasted coffee cells. Some of these oils are insoluble in water and are only used on Espresso machines.
