Vodka

Vodka is a Russian alcoholic drink that is usually about 40% alcohol. It is clear (but can be flavoured), though it is sometimes mixed with other liquids before people drink it. It was first popular in the Slavic countries of Eastern Europe and former republics of the Soviet Union.
Things that are made into vodka
Vodka can be made from different things:
Molasses (which comes from the production of sugar) are used to produce the cheapest vodka. Because of the ingredient, this kind usually tastes sweeter than vodka made from grain. Soy beans, grapes or sugar beets may also be used, but are less common.
Potatoes have been used for centuries to make vodka.
Grain is used to produce the highest grade vodka - like potatoes, vodka is also traditionally made from grain.
The process to make vodka is:
The raw material is crushed and dissolved in water. This is called mashing
The mash is heated to 60 degC. All starch will break up into sugars.
Yeast is added and the mash vessel is closed airtight with airlock. The yeast will ferment the sugar into alcohol.
The fermented mash is then distilled. It can be made either in simple pot still or sophisticated industrial patent still.
If the still used is a pot still, the distillation is usually repeated at least twice to remove any foul-tasting or poisonous impurities away. If the still used is a patent still, the result is spirit; very high contents alcohol unsuitable for drinking. Pure water is added to lower the alcohol contents to desired. This is called dilution.
Unlike cognac or whisky, vodka is not usually matured in barrels, but bottled immediately. Some Scandinavian vodkas called akvavit (Latin aqua vitae, "water of life") are matured in oak barrels before they are bottled. When the vodka is bottled, it is ready for drinking.
History
Most people think the name vodka comes from the Slavic word for water in its diminutive form, "little water". The earliest mention of Vodka in Poland is in 1405. The Russians are known to have first used the word in June 8, 1751. It is not known if it was the Russians or the Poles who made the first drinks that could be classified as vodka, as sources provide various views on this topic (though it's important to remember that the first mention of the word "vodka" in Cyrillic refers to a medicinal drink bought by the merchants of Kievan Rus from Poland). It is also worth noting that vodka was first used as medicine. When it became a popular drink, it was first known in Polish as gorzalka - from the Old Polish word gorzec, meaning burn. At first, gorzalka was a people's drink, but in the Slavic countries it soon became common among the nobility as well. it is worth noting that the common Ukrainian word for vodka is horilka which bears an extremely close resemblance to the Polish gorzalka. Both words roots have the same meaning (hority - to burn; gorzec, also to burn)
Different kinds of vodka
There are two basic kinds of Vodka: clear vodka and flavored vodka. Some types of vodka have plants or herbs added to the unflavored vodka to make it taste better. Contrary to popular belief, flavoured vodka is not new - it has been a part of Polish drinking tradition for centuries. It is only relatively recently in history that clear and flavoured vodkas have found their way to Western countries such as the UK or US.
How vodka is consumed
Vodka is either drunk pure, or cocktails are made with it. The simplest form of cocktail is to mix it with orange or lemon juice. Usually, vodka is drunk during a longer meal. Usually salty or sour things (not sweets) are served. In Poland and Russia (as well as some of their neighbours, such as Ukraine or Lithuania), vodka is drunk from glasses that can hold about 100 grams (0,1 litres) of vodka. The glass is usually emptied in one draught, while holding the breath. Directly afterwards something small is eaten. In most Eastern European countries it is consumed with pickled cucumbers. Before drinking, a toast is given.
Cultural
Vodka is a key element of Slavic tradition in some countries of Eastern Europe (especially Poland, Belarus, Ukraine and Russia). It has also spread to become a part of national culture in Baltic countries like Lithuania and Nordic countries like Sweden. It's traditional in Russia and other Slavic countries (as well as some Roma communities in Eastern Europe) to put a glass of vodka with a slice of bread (usually black bread) on top on graves or near photos of the deceased in their memory. This is similar to what people in Western countries do with flowers.
