In the S03E03 of House of Cards, the Russian president brings this vodka for the US president. Is this real or just a made up vodka since I couldn't find any results on google. Cheers! 
Osobaya Sayanskaya literally translates to Sayanskaya Deluxe or Special Sayanskaya, possibly implying that its origins are in the Sayan Mountains region. There is no real brand of vodka like that, although Sayanskaya Kristaljnaya (Crystal Sayanskaya) vodka does seem to exist. It’s not at all famous or of known special quality however.
