1. Basic knowledge of the six base liquors: The base liquor plays a decisive and leading role in cocktails. The alcohol content of the base liquor is generally relatively high and belongs to the category of spirits. The six common base liquors are: gin, whiskey, brandy, rum, vodka, and tequila.

2. Gin: Gin, its original name in foreign languages ??comes from juniper berries, one of its main flavoring ingredients, so it is often called gin. Gin uses grains (barley, wheat, corn) as raw materials. During the fermentation process, it is mixed with high alcohol obtained by distillation of juniper berries. Various herbs, fruits, seeds, etc. are added to the base of the wine. It is also called redistilled wine.

3. Whiskey: Whiskey can be called "water of life". It is brewed from barley and other grains. After aging in oak barrels for many years, it is finally blended to a strength of about 43 degrees. Distilled liquor.

4. Brandy: Mainly made from wine, but sometimes also made from other fruits. Brandy is a kind of distilled liquor, which is brewed from fruits through fermentation, distillation and storage. Like wine and whiskey, brandy is typically aged in wooden barrels, which adds to its complexity and color intensity. The length of aging and the type of barrel used are both important factors in determining the inherent quality of a brandy. Brandy is a carefully crafted product with special sensory properties and is consumed more often than many other spirits. It can be served at room temperature or chilled over ice; the better the brandy, the more likely it is to drink it cleanly.

5. Rum: Rum is a distilled liquor produced from sugar cane molasses. It can also be called sugar wine. Rum is made from sugar juice pressed from sugar cane, which is fermented and distilled. Rum, especially in its lighter form, is a classic cocktail ingredient. It is used in many of the world's most famous and exotic cocktails.

6. Vodka: Vodka is made from grains or potatoes and is distilled into alcohol of up to 95 degrees. The high-concentration alcohol is then diluted to 40 to 60 degrees with distilled water and passed through activated carbon. Filtration makes the wine more crystal clear, colorless, light and refreshing, making people feel that it is not sweet, not bitter, not astringent, but only has a flaming stimulation, forming the unique characteristics of vodka.

7. Tequila: Tequila is produced in Mexico and is a distilled liquor made from the cactus plant called Agave. The area around Tequila City is the area where Maguey Tequila is produced with the highest quality, and only the tequila produced in this area is allowed to be sold under the name Tequila; if the tequila is produced in other areas, Tguela is called Mezcal. Tequila has a strong taste and unique aroma.
