How to choose your favorite coffee beans

Follow the caf é (Wechat official account vdailycom) and found that Beautiful Cafe opened a small shop of its own.

With the gradual improvement of people's requirements for the quality of life, people's attitude towards coffee is no longer satisfied with the refreshing effect (however, it does not have a significant pick-me-up effect).

Often do not like some people's attitude: how do you put sugar and milk balls in your coffee? Wow! I can't believe you like this fancy coffee. I always drink black coffee. Having been in contact with coffee for such a long time, I still feel that the added value of coffee should not be ignored, but we should face up to the nature of coffee-after all, it is only a kind of drink that makes people happy. Since it is a happy drink, of course how do you like it? I often sprinkle some sugar in my hand, mix it with soda in concentrate, just be happy, don't demonize the coffee.

Well, since you like how to do it, you naturally want to find your favorite coffee right away. Then the next content will introduce the more common brewing methods in your daily life to help you better understand and choose your favorite coffee.

With the rapid occupation of the domestic market by chain coffee brands such as Star Dad, coffee has become the first choice for promotion and daily drinking. in this process, Italian coffee is familiar to everyone because of its convenience of making. Like American style, latte, macchiato, its base is espresso. There is no doubt that espresso is the main driver of coffee retailing. So the so-called espresso, popularly speaking, is the coffee extracted by the Italian coffee machine through high temperature and high pressure.

In coffee extraction, the finer the grindness of the coffee beans, the easier it is to extract, but when you grind the coffee beans too fine to rely solely on the attraction to let the water penetrate the coffee powder layer, you will face a problem of how to increase the pressure to make a full-bodied cup of coffee. So a smart person came up with a solution-using the accumulated steam pressure to push hot water over the coffee layer. Then gradually developed, today's espresso machine operates in 90 ℃ ~ 94 ℃ of hot water, 9 atmospheric pressure to extract a cup of espresso in a short time. On the basis of espresso has evolved a variety of fancy coffee and so on (details will be gradually introduced to you in future push).

So, what coffee beans are used in the production of espresso?

At present, most of the espresso produced in cafes on the market use medium and deep roasting to mix coffee beans, the advantage of blending beans is to have a better balance, because the coffee concentration extracted by Italian concentration is higher, so the balance of flavor is particularly important, so the delicious balanced coffee extracted by other brewing methods will be very exciting with Italian machine extraction. At the same time, the flavor characteristics of beans in different producing areas are slightly different, and different baking and blending methods can fully show a variety of flavors.

From the above description, you should know that the beans used in Italian machines have the characteristics of medium and deep baking and high balance. So why deep baking? In the baking process of raw beans, with the increase of baking time, the moisture content of beans decreases, the pores increase, and the tissue brittleness increases. to put it simply, the flavor will complete a transition from "flower and fruit flavor" to "caramel cream cocoa" and then to "resin spicy carbon roasting rhyme". Then in the face of Italian machine high-pressure extraction, in order to ensure the balance, bakers will mostly change the baking method: the process slows down and bakes deeper.

Now the basic beans that match beans on the market mostly use Mantenin, Brazil, Yunnan and so on. However, Italian mixed beans with good taste, balance and sweetness are not suitable for normal pressure filtration, such as hand flushing, which is also a common way of cooking in the home, it needs to fully show the unique flavor of specific producing areas. In the case of deep baking, it is difficult to distinguish the difference between these two kinds of beans, so these two kinds of beans are often not in common use. But our family's second master Bao is different. But our Italian bean "second master" can not only get on the Italian machine but also do hand flushing. You can also try it or not. It depends on you whether you want to try it.

Knock on the blackboard to sum up

1. For the sake of equilibrium, coffee beans used for Italian machine extraction have a deeper baking degree than fine beans, and most of them are blended. Of course, it is not universal, and single-producing espresso (SOE:single origin espresso) is also a good choice.

two。 Choose Italian beans and weigh them according to the characteristics of your own taste: the deeper the baking degree, the weaker the sour taste, the stronger the bitter taste, and the sweetness shows a bell-shaped curve in the development of baking, that is, between sour and bitter. A good baker knows how to make coffee beans reach the highest sweet spot in every baking degree. Therefore, when you buy coffee beans, you can first ask about the details of the following beans and choose according to your own taste.
