For years convenience stores have sold drinks in quart-sized containers. Now Starbucks is about to debut a 31-ounce “trenta” cup for iced coffee, iced tea and lemonade in 14 states. That’s more than a third larger than the chain’s “venti,” which holds 20 ounces.
Keep in mind that iced coffee with milk and sugar averages 10 calories an ounce and sweetened lemonade has about 14 calories an ounce. If you order the new trenta cup, do the math.
