·Evelic Turkish Coffee:

It is a concentrated, strong coffee with a slight aroma. Heat the copper coffee pot. Put the appropriate amount (1 teaspoon per cup) of coffee powder and sugar into the pot and grind it very finely. After brewing in boiling water for about 1 minute, wait for precipitation before drinking.

■ Filter Coffee:

1.5 1 ounce of lightly roasted, coarsely ground coffee powder into filter paper, slowly pour boiling water into the center of the coffee and around, and then from the periphery back to the center, boiling water through the ground coffee powder drip into the pot, each cup of water about 8~10 grams. Boiling water has a temperature of 100℃.

■ Moka:

A type of distilled coffee brewed in a Moka pot with a steady concentration and aroma. Mocha pot is divided into two parts, in the lower part of the pot water is boiled to a boil, water boiling by steam pressure, rising through the filter containing coffee powder to the upper part of the pot. When the coffee starts to flow to the top half of the pot, turn down the fire, because too high a temperature will make the coffee produce a scorched taste and destroy its original flavor. The common Japanese style of cooking uses the same principle.

■ Napoletana:

A kind of filter coffee, put the moderately ground coffee powder (5~6 grams/cup) into the filter in the pot, cover the filter and put it into the boiler. After the water boils, remove the pot and turn it upside down. The boiling water at 100 ℃ permeates the coffee powder in the filter and drips into the cup. The contact time between boiling water and coffee powder is between 2 and 4 minutes. Napoletana coffee is not very thick, but it tastes full and smooth.

■Espresso machine brewing:

Coffee is an extremely unstable liquid and can change its properties at once. This is one of the reasons why the espresso machine was invented. Espresso machine can extract several cups of coffee continuously, the high pressure in the brewing process can dissolve the oil and colloid in the coffee beans, and the essence in the beans is completely extracted through pressure, making the brewed coffee more concentrated, taste and aroma better.

■ Siphon:

Put the coffee powder into the funnel above first, then add water into the pot, then put the funnel nozzle tightly into the pot mouth, and boil the water. When the boiling water goes deep into the funnel, stir for about 40 seconds to 1 minute, then turn off the alcohol lamp. At this point, when the coffee drops back into the pot, you can remove the funnel and pour it out for drinking.
