Vodka's origins point to either Poland in the 8th century or Russia in the 9th century.

While most Vodka today is distilled using grains such as sorghum, corn, rye or wheat, it also has been known to be made from potatoes, molasses, soybeans, grapes, rice, sugar beets and sometimes oil refining byproducts. However, the Vodka distilled from rye and wheat tend to be the most superior.

Many Vodkas today are filtered and flavored. Unlike many other alcohols used there aren't really types of Vodka other than what it is distilled from. The variations mostly come from the different flavors like lime, orange or even bacon.
