Choose coffee beans for household use and buy hand-ground coffee. What kind of coffee beans do you use to make black coffee?

When you want to buy coffee beans to open Taobao, will you look at the dazzling list of beans and worry? When you go to your own roasting coffee shop, do you struggle with a dazzling array of coffee beans? It doesn't matter! Remember these points, easily choose the right coffee beans!

"choose the type of coffee beans according to your own extraction method."

Now the common coffee beans on the market are divided into two groups: single coffee beans & Italian coffee beans. Individual coffee beans refer to coffee beans produced in a single producing area / manor, and the flavor is generally relatively clean and clear. Italian blending of coffee beans means that the flavor can be maintained for a long time by blending coffee beans from different producing areas, and the flavor is generally mellow and solid.

If you use mocha pot, espresso machine and isobaric extraction, you can choose Italian coffee beans; if you use hand flushing, pressure, ice drop, cold extraction, siphon, American coffee machine and other drip filtration / filtration extraction, you can choose single coffee beans.

Of course, this is not to say that blended coffee beans can not be used for trickle / filter extraction, nor that individual coffee beans can not be used for pressure extraction. In general, the store / roaster will make different baking styles according to different extraction methods, so that a certain flavor / taste of coffee beans is more prominent, so it is more suitable for a certain extraction method. Italian coffee beans taste good when they are used for pressurized extraction, but it does not mean that they can also be used for trickle / filter extraction.

"choose freshly roasted coffee beans packed with an one-way exhaust valve."

Qianjie Coffee emphasizes the importance of fresh roasting of coffee beans all the time, because as the storage days after roasting increases, the flavor of coffee beans will slowly fade away until they are exhausted. So if you want to drink coffee with distinct flavor and layers, you need to check the baking date at the time of purchase. In general, the flavor performance of individual coffee beans is the best within 15-20 days after the baking date, while the best tasting period is within 30 days after the baking date. Italian coffee beans have the best flavor within 30 days after the baking date, and the best tasting period is within 45 days after the baking date.

Are the freshly baked coffee beans the best? It is not that coffee beans contain a lot of carbon dioxide and smoke after baking, which will affect the extraction of coffee and the performance of flavor and taste. So if you buy freshly baked coffee beans, you let the coffee beans rest in a sealed package with an one-way exhaust valve (which removes the gas from the bag while blocking the entry of outside air and moisture) to discharge carbon dioxide and take away the sense of choking (this process is commonly known as soybeans). The date of growing beans will also be prolonged according to the degree of baking. Qianjie recommends 3-4 days for light-medium roasted coffee beans, 5-6 days for medium-deep roasted coffee beans and 7-10 days for Italian coffee beans.

"choose individual coffee beans according to different producing areas, roasting degree and flavor description."

First of all, let's sum up an outline of bean selection: coffee beans from Africa can be selected for those who want to drink sour flowers and fruits, which are generally roasted at a medium and shallow level; those who want nuts can choose coffee beans from Central and South America, which are generally roasted at a medium level; for those who want to be completely sour / bitter, you can choose coffee beans from Asia, which are generally roasted at a medium and deep level.

In the past, the coffee beans sold in the street coffee, for example, the coffee flavor will be different in different producing areas according to the variety of coffee beans, the altitude of planting, the treatment of coffee beans and the degree of roasting. If you really don't know which coffee beans to choose from, you can choose according to the flavor description provided by the store.

In the flavor description, there are more fresh flavors such as citrus, berries, flowers, tea, etc., generally light-medium roasted coffee beans, the sour and sweet taste of coffee will be more obvious; in the description, there are many mellow condiments, such as nuts, dark chocolate, cream and so on. Generally medium-to-deep roasted coffee beans will have a low sour taste and a more mellow and solid taste. In the description, there are some obvious and prominent tonality, such as wine aroma, rich fruit aroma and so on, which are generally specially treated coffee beans, and the aroma / flavor of a certain kind of coffee will be more prominent.

"is it better to buy the original coffee bean or the coffee powder? "

There are many stores that provide the service of grinding coffee powder for the convenience of those who like hand-made coffee but do not have a bean grinder. However, Qianjie suggests that buying the original coffee bean to the original coffee bean can better slow down the dissipation of the coffee flavor, and after grinding into coffee powder, the contact surface of the coffee particles becomes more, and the flavor will dissipate more quickly. So if you drink coffee regularly, you can get a 600 yuan hand coffee grinder and grind it when it's time to make coffee. As long as the coffee beans are in the best taste period, the freshly ground coffee will taste better than the pre-ground coffee.

If you really don't want to buy a grinder but want to experience the pleasure of hand-brewing coffee, Qianjie recommends buying hanging-ear coffee bags. Qianjie hanging ear Coffee is to grind the fresh coffee beans into powder and pack each packet of 10g into a hanging ear filter bag and seal it independently. When brewing, you only need to tear open the package and the sealing strip of the filter bag and add about 150g of hot water at about 90 degrees Celsius to get a cup of fragrant coffee. It is recommended that the coffee bag should not be preserved for more than 30 days.
