How to extract a good cup of coffee by the way of standard extraction and standard extraction

After the correct picking, production and baking, we came to the last two gates of import, grinding and extraction. The two processes complement each other. The thickness of the grinding determines the way in which coffee is extracted. Generally speaking, fine powder is the easiest to extract the essence, so it takes the shortest time, which is extracted immediately after being washed quickly with water of 90 degrees Celsius, using an Italian machine and a mocha kettle. For moderate grinding, it is usually drunk by the family. Preheat coffee cups and coffee pots to make the coffee more fragrant. The water temperature is generally 85 to 90 degrees Celsius, mainly hand flushing pots, dripping pots and siphon pots. As for the coarse powder, it should be on the French kettle, which takes the longest extraction time, and the water temperature is also between 85 and 90 degrees Celsius.

The standard of good coffee

Despite the fact that there are a lot of professional terms used to judge coffee, which are comparable to red wine, you can ignore them all, and your tongue is the first judgment. Mr. Liang said that if the coffee is really good, it is actually very simple: it tastes comfortable, clean, odorless, pure aroma, and the most important thing is that the coffee beans should be fresh. If it had been put on for a year and a half, Xi Shi would have become a bell without beauty.
