The leading Russian dairy and juice group, Wimm-Bill-Dann Foods (WBD), is reportedly considering buying a stake in the country's second-largest juice producer, Multon.

Wimm-Bill-Dann has reportedly estimated Multon's business at US$150m and considered it to be undervalued.

St Petersburg-based Multon said that several companies had expressed interest in taking a stake in the company but there had been no detailed negotiations with any party.
