In the cup test, you always want to evaluate the quality of coffee in an objective and impartial way, but in fact it is very difficult to be objective. Your preset expectations and personal biases will always affect the score of this cup of coffee.

To solve this problem, we can only rely on blind test.

Blind tests not only help you evaluate the cup of coffee more accurately, but also reflect your personal keys and test your taste ability, so let's take a look at what a blind test is and how to do it.

What is a blind test?

The blind test is different from the general cup test, you have no idea what kind of coffee you are drinking, which means that your reaction will be more objective. In addition, in order to achieve a more objective approach, coffee baked by other bean bakers can be blindly tested on the table.

During the blind test, the coffee drinker did not know what coffee was in the cup. In the double blind test, even the organizer of the cup did not know what coffee was on the table.

The goal of the blind test is to find out the best coffee and not to influence the result by anyone's subjective opinion. The factors that will affect our evaluation of coffee are brand (manor), the opinions of others, the price of coffee and so on.

So how do we test coffee blindly?

Does it have to be a bean baker or raw bean seller to hold a blind test? Apparently not. In fact, as long as you love coffee and have enthusiasm, continue to improve your taste senses and taste more different kinds of coffee. We will not teach you how to test the cup here.

Tips and tips

In order to gain more learning experience from blind tests, you can refer to the following suggestions:

1. Take blind tests regularly (especially if you are a bean baker), the more blind tests you take, the more you will gain.

two。 Invite friends who love coffee to hold a wine tasting to train their taste. Then try to match it with beer, cheese, chocolate or other special food and drink.

3. Invite a friend who doesn't like coffee to take a blind test with you, and their tasting description will be very instructive.

Through blind tests, you can challenge your personal prejudices and open your mind to learning. Remember that you may eat hundreds of different flavors every day. When you open the taste buds through a blind test, you can taste the food more attentively and improve your taste ability.
