Chobani founder Hamdi Ulukaya, who has a Turkish heritage, cornered the US market for Greek yogurt by stealing the recipe from one of Greece’s major dairy producers and yogurt makers, Fage, his ex-wife has claimed, according to an ongoing two-year-old lawsuit.

The New York Post reported that Ulukaya got the recipe “by bribing a former employee of Fage,” which was firt in the American Greek yogurt market but was rapidly eclipsed by Chobani’s aggressive ad campaign that frequently featured its founder.

The latest allegation comes in a lawsuit by Ayse Giray, Ulukaya’s ex-wife, who claims ownership of 53 percent of Chobani. In Giray’s account, Ulukaya allegedly met a former Fage employee in Europe and paid him €30,000 ($41,109. Chobani is reportedly in talks to sell a stake to private-equity firm TPG.

While Giray had asked a judge to order Chobani not to proceed with any capital-raising efforts that would reduce her alleged stake, the judge declined to issue a temporary restraining order

In a statement, Chobani said it was pleased with the judge’s decision and described Giray’s claims as ”completely baseless and without merit.” Ulukaya has previously said his recipe was Turkish-based.

Could there be a connection between the recipes used by Fage and Chobani? A Bloomberg Businessweek feature story last year noted that Chobani uses three cups of milk for a cup of yogurt, compared to four at Fage.

A look at the ingredients used today shows a small difference. For instance, Chobani low-fat plain yogurt is made from lowfat yogurt and the live, active cultures “S. Thermophilus, L. Bulgaricus, L. Acidophilus, Bifidus and L. Casei.” Fage 2 percent yogurt is made from Grade A pasteurized skimmed milk and cream and the same live, active cultures.

Fage kicked off the Greek yogurt craze in the U.S. Back in 2007. Before the Greek yogurt boom, Dannon and Yoplait held 71 percent of the overall U.S. yogurt market, with only 2 percent of sales going to Greek-style products (mostly Fage’s).

Chobani has become the second-largest yogurt brand and top-selling Greek yogurt, while Fage has fallen behind.
