PepsiCo has declined to comment on a report that it is interested in buying Russian kvass producer OAO Deka.

PepsiCo has entered talks to buy the Russian company, according to Russia's Kommersant newspaper, which cited people close to the situation. However, it also reported that a Russian businessman, Konstantin Barinov, is seeking to regain a 50% stake in Deka via legal action.

A spokesperson for PepsiCo declined to comment on the report when contacted by just-drinks today (7 October). PepsiCo already has ties to Deka: Last year, the US soft drinks giant launched its own brand of kvass in Russia, named Russky Dar. Deka agreed to bottle the brand on PepsiCo's behalf.

In 2009, meanwhile, Bloomberg reported that Deka might sell a share of its business in order to gain more firepower to do battle with The Coca-Cola Co and Carlsberg-owned Baltika Breweries in the kvass market.

Kvass is a fermented, non-alcoholic beverage sold widely in Russia.
