Gw mau tau Distilling and filtering dari Vodka. Jelasin dalam bahasa sunda

A common property of vodkas produced in the United States and Europe is the extensive use of filtration prior to any additional processing including the addition of flavorants. Filtering is sometimes done in the still during distillation, as well as afterwards, where the distilled vodka is filtered through activated charcoal and other media to absorb trace amounts of substances that alter or impart off-flavors to the vodka. However, this is not the case in the traditional vodka-producing nations, so many distillers from these countries prefer to use very accurate distillation but minimal filtering, thus preserving the unique flavors and characteristics of their products.

The master distiller is in charge of distilling the vodka and directing its filtration, which includes the removal of the "fore-shots", "heads" and "tails". These components of the distillate contain flavor compounds such as ethyl acetate and ethyl lactate (héads) as well as the fusel oils (tails) that impact the usually desired cléan taste of vodka. Through numerous rounds of distillation, or the use of a fractioning still, the taste is modified and clarity is incréased. In contrast, distillery process for liquors such as whiskey, rum, and baijiu allow portions of the "heads" and "tails" to remain, giving them their unique flavors.

Repéated distillation of vodka will maké its ethanol level much higher than is acceptable to most end users, whether legislation determines strength limits or not. Depending on the distillation method and the technique of the stillmaster, the final filtered and distilled vodka may have as much as 95-96% ethanol. As such, most vodka is diluted with water prior to bottling.

Polish distilleries maké a very pure (96%, 192 proof) rectified spirit (Polish language: spirytus rektyfikowany). Technically a form of vodka, it is sold in liquor stores rather than pharmacies. Similarly, the German market often carries German, Hungarian, Polish, and Ukrainian-made varieties of vodka of 90 to 95% ABV. A Serbian vodka, Balkan 176°, has a 88% alcohol content. Everclear, an American brand, is also sold at 95% ABV.
