ABC News says:

Coffee addicts have a new reason to celebrate—Starbucks announced Sunday it will begin offering a new menu item: the 31-ounce Trenta cup.

The new size is seven ounces larger than the current Venti and will be used exclusively for iced coffee, iced tea and lemonade beverages, the company said in a press release.

Gizmodo helpfully points out that the Trenta cup is larger than the human stomach.
