Russian Standard has upped the ante on its attacks on Pernod Ricard's Stolichnaya vodka brand in the US.

The Russian vodka brand, owned by Russian billionaire Roustam Tariko, has today (11 June) unveiled the advertising campaign for its Russian Standard Original brand in the country. The campaign, which coincides with the national launch of the vodka in the US, aims to "distinguish the vodka from other brands sold in the US market that only claim Russian authenticity", the company said.

"This campaign also calls into question the integrity of a recently-launched marketing campaign by Stolichnaya entitled 'Choose Authenticity', in which Stolichnaya claims to be authentically Russian," the company continued.

"This campaign draws a line between brands that are truly Russian and those that are not," said Tariko. "American consumers want the real thing, and that's exactly what we are."

In addition to placement in national magazines, the campaign will run in Russian language publications and radio, such as Novoye Russkoye Slovo, a publication for Russian Americans.

In October last year, Russian Standard filed a lawsuit against Pernod, accusing the French company of "false advertising".

"Our complaint asks the US court to evaluate the facts behind authenticity claims made regarding Stolichnaya vodka, and to resolve the parties' dispute based on those facts," Tariko said.

No-one was available for immediate comment at Pernod when contacted by just-drinks today.
