Starbucks Corp will be releasing its biggest drink size ever, the 31-ounce “Trenta”, in all of its coffee shops in United States by May 3 of this year, the company informed on Sunday.

The new cup size will be available solely for its iced coffee, iced tea and iced tea lemonade drinks in U.S. The newest Trenta is 7 ounces larger than the Starbucks “Venti” cup for iced beverages, which is presently the largest size they had offered.

The company said that ordering drinks for the Trenta size will probably cost consumers about 50 cents more than getting the smaller Venti-sized iced drinks.

Starbucks based in Seattle tested the new size in many U.S markets last year and they have found that it was answering to the customer’s demand for larger cold drinks.

The Trenta size will be launched in 14 states that includes Arizona, Florida, Georgia, Hawaii, Texas and Virginia on January 18 and in California by February 1.

The biggest coffee chain in the world said that unsweetened beverages in the new and bigger size will contain fewer than 90 calories while sweetened versions will contain less than 230 calories.

McDonald’s Corp, the biggest fast-food restaurant chain in the world has taken direct aim at Starbucks with their own frappes, fruit smoothies, and espresso drinks such as cappuccino and lattes. It has also allured customers by selling 32-ounce sweet tea drinks for only $1 each.

U.S convenience stores, which have been competing with restaurant chains with their bigger selection of low-cost and quick-serve fare, have been selling large sizes of fountain drinks for years.
