How to judge and set the grinding degree of espresso

The degree of grinding that changes from time to time

The relationship between grinding and extraction is so close that it extends the technical problem of how to adjust and fix the degree of grinding. The core problem is that the grinding degree of coffee beans is not the same every day.

For example: in fact, there are two or three kinds of coffee beans at home anytime and anywhere, and it is very comfortable and normal to cook them when you want to boil them. After all, when you have equipment, you want to drink all kinds of coffee. Suppose there is only one kind of equipment, but if the roasting degree of different coffee beans is different, it may be necessary to fine-tune the grinding degree in order to get the best effect. At this time, if you can't grasp the grinding variables, you will know the pain, and you can't make high-score coffee.

Another example: if there are more than two kinds of equipment, such as hand flushing and syphon, if there is only one bag of ground coffee powder, you will have a big head. Assuming that it is suitable for hand flushing, the extraction of syphon is bound to be insufficient. If it is suitable for syphon, there is a great chance of excessive extraction.

Of course, there are countless environmental variables that affect the grinding degree of coffee: coffee storage time, water volume, firepower, pressure (espresso), coffee production area, roasting degree, extraction time, and so on. Therefore, if the degree of grinding of coffee can not be controlled in hand, it will cause a lot of trouble, sometimes how to adjust other variables can not produce a good taste (cry)

Coffee grinding degree

From the above three parts, no matter from the theoretical or practical level, it is a key to affect the extraction, but of course, if you use it well, it will be easier to find out the gold variable of brewing and make cup after cup of good coffee, so we will discuss the differences and suggestions on the choice of bean grinders.
