6 minutes to tell you how to choose the "bean grinder"? Adjustment of scale thickness of bean grinder

For professional baristas, please follow the coffee workshop (Wechat official account cafe_style)

I remember that I was very impressed that there was a TIAMO blade electric bean grinder at home, commonly known as the bean chopper, so every time I went home to make American coffee, I had to use it to grind the beans first, but the point came. I didn't know how fine it was to grind. My mother told me that the finer the better (there was really no idea at that time), so after grinding it for a while, I had to open its lid and secretly see if it had been ground. Often see the picture is that some coffee beans have a lot of knives (serious injuries), but some coffee beans are only hastily carried (minor injuries), so together with the bean grinder, shake a few times, evenly, and then continue to grind the coffee beans, and then before long, its fuselage will begin to get hot! It was summer, and how hot it should be in a confined space with no air conditioners and only electric fans.

Ah, the point is that no matter how you grind, 90% of the finished coffee powder must be of different sizes. What on earth is the reason for working so hard? .. I miss the ice table so much!

So Genna secretly told himself that we must buy automatic coffee in the future, and we can also adjust the scale, and we should work hard to make money to buy a better automatic bean grinder for my mother, so as not to let my mother work so hard to drink coffee. Why buy an automatic bean grinder? There are allusions! Another bitter history of blood and tears!

In addition, after a recent crawl, Genna deepened this decision, because each way of brewing coffee has a thickness suitable for its own extraction, and the coffee powder is not too thick or too fine, and then fine-tuned according to its own taste buds. However, the bean chopper not only can not process coffee beans into uniform coffee powder, but also produces a lot of heat in the process of chopping, which will accelerate the oxidation process after being heated. The flavor will also be taken away!

In addition, the coffee powder particles chopped by the chopping machine are thick and fine, which will also lead to the failure of coffee extraction! Even 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! Cause bad taste, so petty bourgeoisie, we have to save money now! (claw!)

Be sure to know about coffee beans before buying a bean grinder

Later, I gradually learned that if you want to buy a bean grinder, you can roughly distinguish between the meaning type and the non-sense type, because the Italian bean mill requires fine grinding, even, preferably as fine as flour, and the calibration interval should be small, on the contrary, for example, hand flushing, racing style, American style, mocha pot and French pressure require large particles, but the key point is to be uniform and not easy to heat.

The size of the powder to grind the beans depends mainly on the way they are cooked. Generally speaking, the shorter the cooking time of coffee is, the finer the ground powder will be; the longer the cooking time is, the thicker the ground powder will be. In terms of actual cooking, the time required by the ESPRESSO machine to make coffee is really very short, so the grinding is the finest, while it takes more than a minute to cook coffee with the "plug air" method, and the coffee powder is ground of medium thickness. American filter coffee takes a long time to make, so the grinding of coffee powder is the thickest.

Grinding coffee powder with the right thickness is very important for making a good cup of coffee, because the extraction of water-soluble substances in coffee powder has its ideal time, if the powder is very fine and cooked for a long time, resulting in excessive extraction, the coffee may be very bitter and lose its aroma. On the other hand, if the powder is coarse and cooked too fast, resulting in insufficient extraction, the coffee will be tasteless because it is too late to dissolve the water-soluble substance in the powder.

How to choose a bean grinder?

So the step of making a cup of coffee and grinding coffee beans is really important, so start choosing a bean grinder that suits you and is affordable in your pocket.

Since Genna is a beginner and has a limited budget, it is set below NT$3000. If you, like Genna, are ready to get a bean grinder, you can start with Pegasus and Little Eagle as a starting point. These two kinds of bean grinders are both operational and easy to use. Here are the data referenced by Genna:

Finally, Genna chose Little Flying Eagle, although Pegasus can grind coffee beans finer, but Genna is mainly used in ice drop coffee, so he chooses a small flying eagle that can grind coffee powder particles more evenly. In this way, the process of ice droplets will also be because the coffee powder particles are the same size, so that the coffee powder extraction speed is the same, the coffee flavor is good, the taste will be mellow and smooth. Then the process of the study also found that if you want to play hands-on replacement or upgrade the cutterhead, Pegasus has higher compatibility with the more popular cutterhead on the market. Genna will open the box of Little Flying Eagle and introduce it to you in detail at that time.
