Tips for making a good cup of coffee-the barista's little knowledge

If you want to make a good cup of coffee, you have to master some tricks.

1. In order to ensure the best solubility of coffee, the water temperature of brewing coffee should be lower than the boiling point. If the water temperature is too high, the taste of coffee will become bitter, but if it is too low, the taste of coffee will become sour, lose its flavor and become thinner.

The barista can keep the water at the best temperature by mastering the performance of the coffee machine, so that the aroma of the coffee can be released without reservation.

Coffee contains 98% water. The quality of the water used to cook coffee has a significant effect on the quality of coffee.

two。 The best water for brewing coffee should be fresh and contain minerals and oxygen, and the hardness of the water should be moderate or lower. If the hardness of the water exceeds 10 °(dH), we would recommend using a filter element called CLARIS.

If possible, the carbonate hardness of the water brewing coffee should be low because the carbonate hardness can have a negative effect on the taste of coffee and produce an insoluble carbonate precipitate. When this occurs, it is recommended that CLARIS plus a filter element be used to remove most of the toxins and chlorine compounds in the water.

3. Precisely because roasted coffee contains as much as 0.1% of the volatile flavor, such coffee has become the most aromatic food. Coffee is very delicate, whether it's unground or ground coffee beans.

Coffee beans must always stay away from oxygen, the main enemy of coffee aroma. For this reason, your coffee beans should always be stored in a sealed container and placed in a dry and cool place.

Once exposed to air, processed coffee beans can keep them fresh for about two weeks. After all this, the coffee quickly stale, becoming boring and stale, and the oil contained in the coffee quickly gave off the smell of rotten oil. Therefore, coffee should be used up as soon as possible.

In order to allow you to enjoy the aroma of your favorite unground fresh coffee beans, use a shaded and sealed vacuum container to maximize the unique aroma of the coffee beans.

There are many brands of manually ventilated storage cans on the market, which are very convenient for families to use.

4. The secret of being the perfect crema

Machines are certainly an important factor in making coffee or espresso with delicious crema, but in addition to machines, other factors also play a decisive role in making "crema" (Swiss term for Schu).

With a thick golden foam, crema is made up of countless oils, proteins and various sugars, permeating most of the mellow aroma of espresso.

Formula determines the quality of coffee

The more oils in the coffee formula, the more unstable the crema. For this reason, espresso is often mixed with some Robusta beans, because these beans contain only about 10% oil compared to high-quality, highly aromatic Arabica beans that contain about 16% fat.

Clean coffee cups

If the coffee cup is unclean and grease remains on the inside of the cup wall, crema will also fade quickly due to the decrease of surface tension.
