Starbucks reported same-store sales up 7% on the year for July, buoyed by its new green tea based drinks.
The group reported consolidated net revenues of $495m (£281m) for the four weeks to 13 July, an increase of 21% from the same period last year.
Jim Donald, the group’s president and chief executive, said: "As we have consistently seen, Starbucks core handcrafted beverages again drove our comparable store sales growth. The enthusiastic response to our new Tazo Green Tea beverages was also a key contributor."
