That's why it's a must to distinguish between the two types of coffee. Hello everyone, today I'm going to talk about why we should distinguish between two types of coffee. Some people who make high-quality coffee, especially Arabica coffee, think that high-quality coffee doesn't need to be distinguished. Some people think that 18% coffee is distinguished, 16% coffee is distinguished, and 13% coffee is sold to whom? Actually, this question is very good. So should we distinguish? First, let's understand what 16%, 18%, 16% and 13% are. This is a figure from the United States. 18 means 18.64 of 1 inch. You divide 18 by 64 and multiply by 1 inch. 1 inch divided by 1 millimeter is 2.54 centimeters, which is 25.4 millimeters. After you add, subtract, and divide, 18 has a diameter like this. It has a diameter of 7.15 millimeters. The same goes for 16. 16 divided by 64 and multiply by 25.4 inches is 6.3 millimeters. 13 divided by 64 and multiply by 2.54 inches is 5.15 millimeters. What is this diameter for? When Westerners developed the coffee industry, it was not unreasonable to divide the diameter like that. You know, it will create favorable conditions for coffee growers. Like this. I'll show you the big one. This is the big one, 18. It will be different. When it's this big, you need more heat to grind it. The heat from the outside to the inside is different. The ratio of small coffee beans to water is also different. So it is necessary to divide the coffee beans. First, why is it necessary to grind coffee beans first? Because when you do this step carefully, first, your coffee beans will look beautiful, which will help you grind the coffee beans evenly. So it is necessary to divide the coffee beans. There is nothing wrong with it. High quality coffee beans do not need to be divided. It's not a 9% ratio. No, it's not a 9% ratio. Many people say, I pick 9% coffee beans. 9% is 100%. So every bean is 9%. So I don't need to divide it. No, it's not like that. It is necessary to divide the coffee beans to make your coffee look even and beautiful. Second, it helps the grinding process to be smooth and even. Third, if you go into the barista industry, you will see that if you use automatic machines, it will automatically measure time. For example, if you grind a double shot of 18 grams, it will measure 8 seconds. If it is 13 grams, it will go much faster. It's about the same. If it's all 13 grams, 18 grams will be shorter than 18 grams. Because when the size is like this, the big beans will be stuck, and the small beans will fall faster. So even just grinding, you will see that creating the same size is also one of the necessary methods. Some customers are very difficult. They only buy 16 grams. Why? So that when they grind it, it's even, the same, and the quantity is stable. So in short, whether to divide or not, in my opinion, you definitely need to divide it. No matter how high-end your product is, you should divide it before grinding and using. If you have any questions related to this issue, please comment below.
