Popular Pumpkin Spice Latte returns to Starbucks Tuesday

(CNN) — Some Starbucks customers are already sipping on the new Pumpkin Spice Latte recipe before it officially rejoins the menu Tuesday.

The coffee chain announced last week that fans of the beverage could get it before its official launch date by entering a not-so-secret password on PSLFanPass.com.

Over Labor Day weekend, baristas are making the latte for anyone who unlocks the fan pass.

They’re getting a first taste of the drink’s new recipe: Starbucks said it answered customer demands by taking out artificial flavors and colors and adding real pumpkin.

Starbucks said it’s the company’s most popular seasonal menu item ever. A “tall” size has 300 calories.
