The seasonal drink that made pumpkin spice a star is turning 20. And unlike the autumn days it celebrates, there seems to be no chill in customer demand.
Starbucks’ Pumpkin Spice Latte goes on sale Thursday in the U.S. and Canada, as it does each year when the nights start getting longer and the fall winds gather. It’s the coffee giant’s most popular seasonal beverage, with hundreds of millions sold since its launch in 2003. And it has produced a huge — and growing — industry of imitators flecked with cinnamon, nutmeg and clove.
