The Russian companies Russky Standart Vodka, LVZ Topaz and Sibirsky LVZ produce vodka and are competitors in the market. Topaz and Sibirsky produce and sell vodkas like Green Mark Traditional Recipe, Green Mark Rye and others. The neck of every bottle of those brands carries a collar reading "Vodka No 1 in Russia". It is obviously implied that Topaz and Sibirsky produce the best quality vodkas on the Russian market. The Russian Antimonopoly Service is a watchdog for incorrect marketing practices and directed its attention to that statement.
