Starbucks is adding a new cold beverage as the popularity of iced coffee continues to grow. Starting today (Tuesday), the coffee chain is adding a new chocolate cream cold brew to its menus. A Starbucks spokesperson says it's supposed to remind people of that "last bit of melted chocolate ice cream on a warm summer day." Last week, Starbucks Interim CEO Howard Schultz said cold beverages like iced coffees and Frappuccinos account for almost 80% of their business. Is there a coffee drink you hate to admit that you secretly love? What treat automatically means "summertime" to you?
