Generally in the outside often drink shoddy canned coffee, coffee bags are easy to make people palpitation reasons, in addition to picking beans procedures can not be too accurate. The main reason is that the beans used in this cheap coffee are Robusta, not the well-known Arabica. Robusta has low planting cost, high caffeine content and poor taste, so there is little circulation on the market. Seasoned coffee, instant coffee and canned coffee will be seasoned in the factory first, so they can better overcome the problem of poor flavor. (usually the only need to drink this kind of coffee is caffeine)

On the other hand, most of the Arabica species that make people feel palpitation have problems in quality. the raw beans imported from the place of origin will inevitably be mixed with some poor quality beans, even branches, gravel and other sundries. Although the cost of picking beans by hand is high, the time of picking beans each time is often longer than the time of baking beans, but it can pick out bad beans more accurately. In addition to affecting the overall flavor of coffee, bad beans even carry biotoxins that affect the health of drinkers.

Choice of Italian coffee beans: how to choose good Italian coffee beans?

A good cup of boutique coffee must be hand-picked bad beans, moth-eaten beans and unripe beans. Wait for a lot of careless bad beans to be formed. Instead of picking beans mechanically, we use air ducts to filter out pebbles and other sundries in the factory, but it is impossible to effectively distinguish the advantages and disadvantages of raw coffee beans, even though the use of factory mechanical beans is quick and cost-saving. but these coffee can only be said to be inferior coffee.

Raw beans that have not been picked out are baked and drunk into the consumer's body. In addition to ingesting toxins, it is also easy to feel palpitations and other uncomfortable symptoms. Hand-picked high-quality beans are definitely better than mechanically selected bad beans in terms of aroma and taste.

The most important thing in the selection of Italian coffee machine is the stability of extraction, including the stability of pressure and the stability of water temperature. The stability of the coffee machine extraction can be judged by the appearance of the finished coffee. You can see that there is a very rich and stable coffee oil on the coffee surface, which can be used to judge the coffee machine. The grease is not particularly obvious or dissipates very much, indicating that the extraction state of this cup of coffee is not very ideal, which shows that the performance of this coffee machine is not very good. Semi-automatic espresso machine, this needs to be equipped with a special bean grinder suitable for Italian coffee. The mode of the automatic espresso machine is set, the machine is mixed, and it may be limited to drink coffee with different flavors. The American drip filter coffee machine uses a very simple method to extract hot water directly through the coffee powder. The biggest difference with the Italian coffee machine is that there is no high pressure. Considering the difficulty of operation, it is recommended to buy American drip coffee machine.

The second step is to buy some high-quality coffee beans.

Coffee beans must be fresh, only freshly roasted coffee can have a very mellow flavor. When buying, you should also pay attention to whether the color and particle size of the beans are uniform. Good coffee beans are not only shiny in appearance, but also have a strong aroma without being mixed with peculiar smell. Netizens had better go to the fresh coffee bean baking spot near home to buy some roasted fresh beans or go to a well-known online store to buy roasted coffee beans. It is more difficult to bake at home, netizens generally do not have to try, if it is a coffee enthusiast can buy a small bean roaster to try. )

The third step is to grind the coffee powder yourself at home.

As far as the average family is concerned, you can buy a nice hand bean grinder for 2 cups of coffee. Manual bean grinder is cheaper and more fun than electric bean grinder, which is suitable for cafes. The ideal time to grind coffee is to grind it before cooking. Because ground coffee is easy to oxidize and lose its flavor, especially without proper storage, coffee powder is also easy to change flavor, so it is naturally impossible to cook mellow coffee. There are different brands and types of bean grinders for grinding coffee, and the ideal one is a grinder that can adjust the thickness of the beans.
