How long does it take to roast coffee beans? taste good. Roast coffee beans are concentrated.

1. The choice of raw coffee beans is very important

The choice of raw beans directly determines the final taste of coffee. Without good quality raw beans, it is impossible to drink good coffee. Blending different coffee beans in different proportions may form a better taste than raw beans, but if you want to drink a more pure taste, you should still pay attention to the choice of raw beans.

2. Coffee roasting

Coffee beans are roasted in a roaster (a large rotary barrel). After 5-7 minutes of high heat, fully dry the residual water in the coffee, at this time the color of the coffee will also change, slowly turn yellow, and you can smell the strong aroma of the coffee.

In a few minutes, you can hear the popping sound of the coffee, at this time, the size of the coffee beans will double, and with the "crackling" sound (similar to the sound of popcorn), the color of the coffee will turn dark brown, but it should be noted that the coffee is not roasted well at this time, there is still a very strong sour taste, and the coffee needs to be roasted.

3. The release of coffee taste

About 15 minutes after baking in the roaster, the taste of the coffee will be fully released (but it also depends on different types of coffee), which also means that the coffee roasting process is over.

First, the use of vertical sealing cans. Because the proportion of carbon dioxide is higher than the principle of air, the carbon dioxide released by fresh coffee beans will be stored at the bottom of the container, similar to the production of antioxidants to protect the coffee beans. In terms of containers, it is best to choose vertical storage to prevent the loss of carbon dioxide in sealed cans or bags, so it is more appropriate to choose upright sealing cans with openings upward.

Second, use a long spoon to get coffee beans. It is the same as the principle of the specific gravity of carbon dioxide, so carbon dioxide accumulates at the bottom, so do not use pouring method when taking coffee beans, otherwise the essence of the container, that is, carbon dioxide, will be poured out at the same time.

Third, the opaque light is the best for the vertical sealing tank. Because the light is the catalyst of oxidation, the choice of opaque vertical sealing tank can slow down the speed of oxidation. Although most of the lids on opaque cans are transparent, it is recommended that coffee beans should be treated as transparent as possible after storing coffee beans in cans.

Fourth, use vacuum cans. There are many vacuum cans on the market, most of which draw or take out the air in the tank to form a vacuum, in which there is no oxygen and moisture, so it will also be a way to store coffee beans.

Put it in a cool and dry place as far as possible. If the roasted coffee beans are placed in a place of high temperature, it will easily lead to the volatilization of the aroma of the coffee and the excellent substances inside. Therefore, it is best to avoid placing coffee cans in a high temperature environment, and it is best to choose a cool and dry place.
