NEW YORK (CNNMoney) -- Starbucks will offer a new plus-sized iced drink beginning this week.
The "Trenta" will be 31 ounces -- one ounce shy of a quart -- and available for iced coffee, Tazo shaken iced tea and iced tea lemonade.
The Trenta-sized drinks will cost 50 cents more than its current tallest drink, the 24-ounce "Venti Iced," according to Starbucks. The tallest hot drink is the 20-ounce "Venti."
Starbucks spokeswoman May Kulthol said the drink has less than 90 calories when unsweetened, or less than 230 calories when sweetened.
She said the release of the new drink is partly in response to customer requests posted online, and partly in response to employee suggestions. The plus-sized drink has been in testing for about a year, she said.
Starbucks is rolling out its new drink just days after changing its logo on Jan. 5, in recognition of its 40th anniversary.
The Seattle-based chain dropped the words "Starbucks Coffee" from its logo and brought its green Siren character out of her confining circle. The reaction from customers was tepid, but Starbucks said it is standing by the decision.
