Spokesman Jim Olson said the price increase will affect beverages such as Starbucks' brewed coffee, tea, latte and espresso drinks, CNNMoney reported Friday.
Noting drink prices vary from city to city, Olson said customers in some markets could pay about a dime more for a tall brewed coffee.
But, Olson said, less than a third of all Starbucks beverages will be affected by the price hikes. For example, he said, prices won't increase at a majority of Starbucks stores for venti and grande-sized brewed coffees or for its Frappuccinos.
He said the Seattle-based company's first price hike in nearly two years was triggered by rising costs for labor, raw materials and rent.
