Starbucks (NASDAQ:SBUX) has a new dairy offering -- but don't try adding this one to your coffee.

On Tuesday, the Seattle coffee company announced that it's teaming up with France's Danone (NASDAQOTH:DANOY) to begin marketing a "jointly created and developed" selection of specialty yogurt products.

The new yogurt offerings, branded "Evolution Fresh, Inspired by Dannon," will be sold in Starbucks coffee shops, beginning in spring 2014, and subsequently marketed by Danone to grocery stores in 2015. If successful, the product may be marketed globally thereafter.

The companies further noted that they may be cooperating on other products in the future.

In possibly related news, shares of a Danone sometimes-partner, sometimes-rival in the drinkable yogurt market, kefir-maker Lifeway Foods (NASDAQ:LWAY), is seeing its shares come under pressure Tuesday. Specializing in grocery sales, Lifeway also operates a chain of yogurt-inspired restaurants of its own known as "Starfruit Cafe." As Danone shares gain 0.5%, Lifeway is down 4.5%.
