According to Starbucks, the Pumpkin Spice Latte, or PSL, is the company’s most popular seasonal beverage of all time. It was almost named the Fall Harvest Latte.

The drink began in a research development lab, where tasters sampled pumpkin pie with espresso to find the exact taste.

Since then, Starbucks expanded its pumpkin spice offerings to include Ready-to-Drink Pumpkin Spice Latte, Pumpkin Spice Flavored Ground Coffee, Pumpkin Spice Caffe Latte K-Cup Pods, Iced Espresso Classics Pumpkin Spice Latte and VIA Instant Pumpkin Spice Latte.

For those who aren’t crazy for the PSL but still want some of the taste, Starbucks customers can request to add a drizzle of pumpkin sauce to any regular drink.
