NEW YORK (AP) — The bigger-is-better concept seems to be striking a chord among some Starbucks customers.

Starbucks will begin a phased-in nationwide rollout Tuesday of its Trenta cup size that can be filled with just shy of a quart’s worth of iced beverages such as coffee, tea and lemonade.

Starbucks Corp. says Trenta, which means 30 in Italian, will be 31 ounces and cost about 50 cents more than the 20-ounce Venti size.

The new cups will be introduced in the South and Southwest beginning Tuesday, in California on Feb. 3 and expanding nationwide by May 3.

The expansion comes after the café chain tested the 31-ounce cup in several markets last year, including Phoenix, Tampa, Fla., and Atlanta.
