Short, Tall, Grande, Venti, Trenta?

When your Venti-sized Starbucks just isn’t enough caffeine, here comes the trenta.  This 31-oz iced tea or coffee is being tested in select areas.

But no, you cannot get your favorite latte-based or frap drinks in the trenta, only iced coffee or tea.  Can you imagine the calories in a trenta-sized frappuccino??
