Mistakes in learning [cup test]: [taste map]-all tastes are produced in the whole mouth.

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

Recently, people who want to open a coffee shop seem to have a common understanding-baking their own beans. So the proportion of self-baking shops is getting higher and higher. The degree of inquiry about the opening of the course is also getting higher and higher.

At first, it took more than 10 years to figure out the process and theory of baking beans and finally got something, but the age also reached the limit of physical effort. Of course, doing machinery also takes up most of the time, and when the physical strength is gradually exhausted, it is difficult to have the spirit to pay attention to other related projects, so it is time to turn our energies to the discussion of establishing baking theory.

Most of the people who will come into contact with coffee roasting are drinking and cooking, and some of them often drink outside until they have heart palpitations and vomiting, and suddenly find that they can't bake. The other is a pure desire to do business, depending on what is popular to hitch a ride.

The ancient dog god is really the most amazing invention of our time. Hundreds of thousands of answers to any question can be found between fingers, and then a message will be posted to complete the task of helping the poor and saving people. In a short period of more than 10 years, the acquisition of information is really incomparable.

I think I just wanted to buy a raw bean and hit a brick wall everywhere. I asked too many questions and didn't know how to buy it. Now, in order to sell your raw beans, the origin information, cup test report and recommended baking method are all completely attached, and even some people offer baking and drinking. It's so convenient and happy.

Now the Internet is developed, and access to information is quite easy, so all kinds of coffee theories are also mutually exclusive. In such a flood of information, the most obvious phenomenon is that [keyboard experts] make up the number. What is a keyboard expert? A person who goes around looking for other people's experience to answer questions. Among these keyboard experts, the strangest thing is that they know nothing and create a new theory after digesting and merging the experiences of others. Then palindromes are honed everywhere and become like experts and masters. What is more, they worship the docks everywhere, leading parties and factions, and they are in collusion with each other, which is really admirable.

However, this has also caused a great deal of trouble to me. Many people come to me with the right answers from all over the place. For example, the action of [removing fine powder], why should the fine powder be eliminated? Because the powder is too fine, it will have mixed smell. My answer is that there will be [miscellaneous smell] is a matter of baking and cooking, regardless of thickness. If the baking is good and the cooking is good, then the fine powder will increase the concentration of the released ingredients, and the mixture of thickness and thickness can show layers and richness, and will not produce miscellaneous smell. If the purpose of removing fine powder is consistency. Of course, get rid of the fine powder, if it is because of mixed smell, then you have to review the problem of baking or cooking. First of all, it is necessary to determine whether it is a problem of cooking or not. only by making sure that it is not a problem of cooking can we review the problem of baking.

Many problems must start with the most basic parts before the truth can be clarified.

What determines the taste of a cup of coffee today? Drink, of course! This is also the reason why many people are willing to spend a lot of money on cup testing.

However, there is generally a serious mistake in learning the cup test: the taste map.

In other words, it is generally believed that [sweet] at the tip of the tongue, [salty] on both sides of the tip of the tongue, [acid] on both sides of the waist of the tongue, and [bitter] at the base of the tongue.

This is clearly written in Wikipedia:

Here is an excerpt from Wikipedia about taste and taste buds:

All of these tastes are produced throughout the mouth, rather than having a taste map with different sensitivity to different tastes in different areas of the tongue, as is often misunderstood. This rumor is often thought to be caused by a mistranslation of a German textbook, which was widely used in North American schools in the early 20th century. It is true that there are slight differences in sensitivity between different compounds in different regions, but this is not easy to detect, and whether it is completely consistent with this so-called taste map has not been confirmed. In fact, each taste bud (which contains about 100 taste sensory cells) usually corresponds to the five basic flavors caused by the compound.]

Different tastes are not felt in different positions of the tongue. All taste buds can recognize all flavors.]

This is a typical example of a wrong theory based on a mistake.
