Starbucks 31-oz “Trenta” cup size set for U.S. debut

Starbucks Corp will roll out its biggest drink size yet — the 31-ounce “Trenta” — in all of its U.S. coffee shops by May 3, the company said on Sunday

The new size will be available only for iced coffee, iced tea and iced tea lemonade drinks in the United States. The Trenta is 7 ounces larger than Starbucks’ “Venti” cup for iced drinks, which currently is its largest size on offer.
