About half of Starbucks sales are before 11 a.m. So the company wants to expand lunch and afternoon business through non-coffee products like food, juice and Fizzio soda. Now Starbucks will start testing Evolution Fresh smoothies made with Dannon Greek yogurt. The company will test three flavors in 200 Starbucks in San Jose and St. Louis starting Tuesday, and a full line is expected to be in all markets next year.
