Coffee is loved by the vast number of white-collar workers, but most people usually do not know how rich the different flavors can be if they choose coffee with different roasting levels except simply ordering a cup of coffee with different brewing styles.

Different baking, different tastes.

From green coffee beans, roasted to golden yellow, the aroma, acidity and bitterness of coffee beans are balanced, which is a prerequisite for a good coffee. If the coffee beans are not roasted correctly, no matter how they are brewed by the master, this cup of coffee can not hide its deep congenital regret.

However, if you say that different baking methods can change more than 20 completely different flavors, it is indeed rare to see a demonstration. A few days ago, Yangcheng Evening News reporter participated in the Starbucks Gold roasted coffee launch event, under the leadership of experienced coffee roasters, on-site evaluation, only through the sense of smell can also distinguish rich differences. Some of the different coffee beans are closer to the floral flavor, some are fresh and citrus, some are thick or woody, and even taste like mushrooms after the rain.

In fact, different degrees of roasting will make the same kind of coffee beans show different characteristics and flavor. Light roasted coffee usually has strong acidity and light aroma, while deep-roasted coffee is rich in oil, sour is replaced by scorched bitterness, and has a unique flavor; for moderate roasting between the two, it pursues a balance between sour and bitter taste, with bitter in sour and a long finish.

City coffee has different styles.

Traditionally, people would think that Italians and Brazilians prefer deep baking, while Americans prefer light baking. Different coffee beans have different baking requirements. For example, Guatemala Antigua coffee beans retain their sour and fruity flavor during deep roasting, while Sumatran coffee beans lose acidity during deep roasting, so keep their roasting lighter. Of course, just like the immigrant city of New York, globalization has made people's tastes more and more complicated, and it's hard to say that a particular region always maintains a preference for a certain taste.

Doug Langworthy, a master roaster of Starbucks coffee, said: "in fact, we can't say which baking flavor is more popular." Medium or deep baking still has its fans. But many of my friends also prefer coffee that is light but soft and round. "

Yangcheng Evening News: what is the effect of different degrees of baking on the flavor of coffee?

Doug: in terms of taste, people like the style of coffee baked in different degrees, so it's hard to say whether it's high or low. However, light roasted coffee is more demanding for coffee beans. Because of the heavy baking, the charred aroma is more rich, while the light baking, if the coffee bean itself has miscellaneous smell, it is easy to show, greatly affecting the taste.

Yangcheng Evening News: do Chinese people prefer coffee? Will new varieties be developed according to Chinese tastes?

Doug: China has a vast territory, so it's hard to say that there is a uniform taste for coffee. But now more and more people will try different flavors brought by different roasting, which is the progress of coffee culture. This gold roasted coffee is not specifically developed for the taste of the Chinese population, but we are also looking for coffee beans suitable for Chinese taste in China. For example, the "Fengwu Xiangyun Comprehensive Coffee" from Yunnan is made in China and is specially sold in China. It can be said to be a kind of coffee aimed at Chinese taste.

Yangcheng Evening News: for consumers, has bought a certain degree of roasted coffee beans, is it possible to change the flavor through brewing techniques?

Doug: the best advice is to find out the variety and roasting degree of coffee beans that suit your taste by tasting coffee blindly or in large quantities, and on this basis, you can enjoy more delicious coffee by making a good cup of coffee.
