Starbucks raising some U.S. cafe drink prices NEW YORK (Reuters) - Starbucks Corp (SBUX.O) will increase the price of some of its beverages in U.S. company-operated cafes by as much as 10 cents, the first price change in up to two years, a spokeswoman said on Friday. The price hike will be effective June 25, Starbucks spokeswoman Lisa Passe said. "Less than a third of beverages will be affected by the price increases," Passe said. In most stores, the price of a Grande or Venti brewed coffee, as well as Frappuccino and Refreshers, will remain the same. Nationally, the average beverage purchase price increase will be about 1 percent, she said. The most a tall brewed coffee will increase by is 10 cents, while some markets will not see any increase in brewed coffee, she said. Green arabica coffee prices dropped to a four-year low on the ICE Futures U.S. market at $1.1710 per lb on Thursday. Coffee commodity costs make up less than 10 percent of Starbucks' overall store operating and occupancy expenses, Passe said. Reporting by Marcy Nicholson; Editing by Gerald E. McCormick
