Great news, friends. Today marks the opening ceremony of the Sochi Olympics in Russia. That means no one will judge you for making all the vodka drinks [1] your little heart desires. One of the purest and most popular spirits around, vodka is worth celebrating today and all Olympics long. But before you do, take a minute to test your knowledge on the tipple with this oh-so-informative quiz. The world may never know whether the liquor originated in Russia or Poland, but you can still brush up on other fun facts. Cheers!
