How to choose the bean grinder? Take three minutes to read it and give yourself a choice of thinking and comparison.

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. 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 the lid and secretly see if it had been ground. The picture we often see is that some coffee beans have suffered a lot of knives (seriously injured), but some coffee beans have only been hastily cut (slightly injured), so they have to shake them together with the bean grinder, shake them evenly, and then continue to grind the coffee beans, and then before long, the fuselage of the coffee bean will start to get hot! It was summer, and in a confined space with no air conditioners and only electric fans, how hot should it be? the point is that no matter how ground it is, 90% of the finished coffee powder must be of different sizes. .. I miss the ice table so much!

So we secretly told ourselves in our hearts 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 my mother a better automatic bean grinder, 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 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 speeds up 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-meaning 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 very coarse and cooked too fast, resulting in insufficient extraction, then the coffee will be insipid because there is no time to dissolve the water-soluble substances 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 Gina is a beginner and has a limited budget, she is set below NT$3000. If you, like Genna, are ready to get a bean grinder, you can start with Pegasus and Flying Eagle. These two kinds of bean grinders are both durable and easy to use. Here are the data referenced by Genna:

The last choice is Pegasus. Although Pegasus can grind coffee beans finer, 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 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 change hands or upgrade the cutterhead, Pegasus is more compatible with the more popular cutterhead in the market. Gina will open the box of the little flying eagle, and then I will introduce it to you in detail.
