SEATTLE ( TheStreet) -- Starbucks ( SBUX) is looking to expand, and not just in emerging markets . Starbucks plans to roll out the Trenta, a new 31-ounce beverage cup size. Starbucks' Trenta, Italian for the number 30, will actually hold 31 fluid ounces (nearly a quart) and will set customers back 50 cents more than if they purchased the next largest size, the Venti, which holds around 24 ounces.
Trenta-sized offerings will be cold beverages only, such as iced lattes, iced teas and coffees, frappuccinos and lemonades. It will be available nationwide on May 3, in time for customers to fill up on iced beverages as the weather warms up across the U.S. A phased-in roll out will precede that. The Trenta will be available in 14 states beginning Tuesday -- Virginia, North Carolina, South Carolina, Georgia, Florida, Alabama, Mississippi, Louisiana, Texas, Oklahoma, New Mexico, Hawaii, Nevada and Arizona. California customers can order the Trenta beginning Feb. 1. Starbucks tested the 31-ounce cup size in several markets -- such as Phoenix, Tampa, Fla. and Atlanta -- before deciding to roll out the extra large offering nationwide.
