Bean grinders are often directly ignored in coffee recruits! This is a really sad fact! Many novices buy coffee powder directly in the supermarket. But friends with a little common sense will know that the shelf life of coffee after roasting is very short. It is generally recommended that freshly baked beans should be drunk within 1 month! Because in a month's time, the elements in the beans that can bring you the ultimate flavor will be quickly lost. Coffee ground into powder oxidizes faster because of its larger contact area with air. Generally speaking, 15 minutes after grinding is enough to turn the original boutique coffee into waste. That's why some people or merchants always advertise that our coffee is freshly ground coffee! Although sometimes those merchants themselves do not understand why they want to grind!

Some friends here will say, as long as it is not grinding right now!? I bought a few dozen yuan of spiral bean grinder on Taobao and now I can OK it. In fact, as long as your beans are good enough and fresh enough, it must be much better than buying coffee powder directly to brew and extract! But you still waste coffee beans! A spiral bean chopper (we call it a bean chopper because this machine crushes beans by chopping rather than grinding) not only can't process coffee beans into uniform coffee powder, but also generates a lot of heat in the process of chopping. Coffee powder accelerates the oxidation process when heated. The flavor will also be taken away! In addition, under the first principle of successful extraction of boutique coffee (uniform extraction), because the coffee powder particles chopped by the chopping machine are coarse and fine, it will also lead to the failure of coffee extraction! The most direct is excessive extraction, or insufficient extraction! The coffee with insufficient extraction will be sour and astringent, and the coffee with excessive extraction will be too bitter!

Taste-balanced and thick in the mouth, long-lasting and obvious, is good coffee, but whether the taste is mellow or not is closely related to the method of brewing, such as brewing misses the point.

Humidity factors play a role not only in sunny and rainy days, but also at different times of the day. Generally speaking, the humidity in the morning and evening is higher than that at noon, so according to the influence of humidity factors, the grinding degree should be thickened in the morning and evening, and finer at noon.

There are many other factors that affect the degree of grinding, including the roasting degree of coffee beans (although coffee beans used by Espresso should use a deeper roasting degree, but sometimes different roasting degrees may be used to roast formula beans for richer taste), blended recipes, and so on. All of the above are the most common and can be mastered by baristas. The previous sections are all about the adjustment of the basic factors in the production process in order to meet that taste standard on the premise of understanding the good taste of Espresso (see the taste of Espresso). There are many places in the world of Espresso that we don't fully understand, and we would like to explore this wonderful world of coffee with you.
