Why is this cup of coffee so raw? Wu Xiwen, director of the well-known catering classroom, said that the quality and baking process of coffee directly affect whether the coffee is good or not. For example, if the shallow roasted coffee is not cooked, it will be astringent.

Wu Xiwen said that there must be five conditions for a good cup of coffee: the first is the quality and roasting of coffee, the second is to use good energy and running water, the third is to choose brewing utensils, the fourth is heat and temperature, and the fifth is the skills and methods of brewing. As long as there is a condition that does not perform well, it will affect the quality and taste of coffee.

He explained that if the coffee beans are of poor quality, the internal fibers are loose, and there is still bitterness after baking, the shallow roasted coffee will drop the beans a few seconds after the first explosion, and it will have a raw taste before it is fully cooked, but is it "second explosion"? It depends on the type of machine, depending on the kind of bean.

If it is not shallow roasting, he points out, after the second explosion of coffee beans, we should also pay attention to avoid stir-frying to scorch, so there is a scorched and astringent taste.

In terms of water use, he said bluntly that we must use good energy and live water. if we use acid water to brew coffee with reverse osmosis, it will be sour; if we brew coffee with tap water, it may have a peculiar smell and miscellaneous smell.

The choice of brewing utensils is also very important, using siphon, filter paper and filter bags, Italian coffee machine, the taste of coffee is completely different. Siphon drifting and rolling method, the release concentration and glycol are the most balanced and complete; hand-brewed coffee filter paper and filter bags are only osmotic filtration, which can not completely release the coffee ingredients, but the effect of flannel filter bag is better than that of filter paper. generally speaking, under the ideal concentration, the ratio of coffee to water is 1: 10.

The water temperature is too low to make strong coffee, the water temperature is too high and it is easy to flush out the scorched and astringent taste.

When it comes to brewing techniques and methods, he analyzes that if siphon coffee is used to brew coffee, the flavor of coffee brewed by cross plucking or rotating is different; if you use filter paper and filter bags to brew coffee by hand, small circle and large circle, the coffee is also different.

Therefore, it is not easy to brew a good cup of coffee. Only when the above five conditions are gathered together can it be called a good cup of fine coffee.
