|The production process of vodka|
What is vodka?
Vodka is a traditionally colorless and tasteless distilled spirit that can be enjoyed purely (completely used alone) or as the base of many cocktails, including Vodka Martini, Bloody Mary, and Metropolis. Although the origin of vodka is uncertain, some historians believe that this distilled spirit originated in Eastern Europe (Russia or Poland) in the 15th century for medicinal purposes.
Traditional vodka is made from two raw materials: water and ethanol from the fermentation of grains such as wheat, sorghum or rye. Many vodka brands use other basic ingredients (such as potatoes and beets) and additives (such as botanicals and spices) to achieve a unique personality in their wines. After vodka is fermented and distilled, it is filtered and refined to remove impurities and achieve a smooth taste.
What is vodka made of?
A bottle of vodka is one of the simplest wines, made from the following ingredients:
Fermentable base wine: Most alcohol brewing starts from agricultural products that have undergone a fermentation process. Potato vodka is generally considered the most traditional alcohol recipe, but the most common raw material for vodka is a mixture of grains, such as wheat, sorghum or rye. After the fermentation process, this base produces ethanol, and vodka manufacturers sift out the ethanol from the solid mixture, leaving pure liquid alcohol.
Water: After the distillation process, the vodka manufacturer adds water to the product to achieve the required alcohol level. For alcoholic beverages classified as vodka in the United States, their alcohol content (ABV) must not be less than 40%; in the European Union, the amount of vodka must be at least 37.5%.
Optional additives: Although traditional vodka is tasteless, some vodka brands add botanicals, spices, or flavors during or after distillation to make their wines distinctive.

How is vodka made
Most vodka manufacturers follow a few basic steps to produce vodka:
1）Combine basic ingredients. To make a fermentable base wine, vodka makers mix grains (such as wheat malt, corn flakes, or rye) with water and yeast. They then heat and stir the mixture (sometimes called "vodka mash") to make sure it is well mixed and ready to ferment.
2）Fermentation base. Vodka manufacturers then store their base mixture for a specified period of time—usually between one and two weeks—to fully ferment the mixture. In this fermentation step, the compound begins to decompose and produce a simple natural alcohol called ethanol or ethanol.
3）Filter the mixture. After the fermentation is complete, the vodka manufacturer filters out the liquid from the fermented solids. They discard solids and use liquid (ethanol) to make vodka.
4）Distillation. Distillation is a process of purifying the liquid by heating and evaporating the liquid, and then collecting the vapor as it recondenses into the liquid. The resulting liquid is considered purer (because it leaves many impurities when it evaporates) and has a higher alcohol content. Vodka manufacturers all use different distillation methods-some may only be distilled once or twice, while others may require multiple distillations and re-distillations to obtain a purer result. If they are making flavored vodka, they may also choose to add botanicals during the distillation process-some have botanicals soaked in ethanol before or between distillations, while others use special distillers during the distillation process Add botanicals.
5）Collect and sort products. The liquids distilled by vodka manufacturers are not exactly the same-when ethanol is distilled, the liquid produced changes. The first 35% of the ethanol product produced by the distillation contains methanol or acetone, and may be highly volatile or toxic-containers of this liquid are called "preliquids" and "heads", and the distiller usually throws them away. The bottom 30% contains "heart", which is the best product. The last 35% are "tails", they are impure, but they can be kept and redistilled to get more product.
6）Filter. Because traditional vodka is tasteless and smooth, many vodka manufacturers will add an extra step to their production line-filtration. Once they have determined the core of the distillate, they will pass the product through a large filtration system (usually using charcoal or carbon) to ensure that the final product has a good, clean taste.
7）Dilution. Once the distiller gets their distilled product, they will test the alcohol volume (ABV) and gradually add water to dilute the vodka to the required alcohol content.
8）Bottle. The final step is the bottling process, where the vodka manufacturer adds the final product to the labeled bottle.
