Which Starbucks seasonal latte was first tested in 2003 before its national launch?

The Starbucks Pumpkin Spice Latte was first tested in 2003 before its national launch.

Starbucks developed the drink while looking for a new autumn beverage. Early testing compared pumpkin-flavored ideas with other seasonal flavors, and the final drink combined espresso and steamed milk with pumpkin, cinnamon, nutmeg, and clove notes. It became a recurring seasonal product and one of the company’s most recognizable limited-time beverages.

The drink is commonly abbreviated as PSL. Its popularity helped make pumpkin spice a broad autumn flavor trend in food, drinks, candles, and desserts.

The Pumpkin Spice Latte is not the same as plain coffee flavored only with pumpkin. It is a formulated espresso beverage, and recipes have changed over time, including adjustments to toppings, ingredients, and serving options. Its annual return date can also vary by year.
