Despite it still being summer, Starbucks is already ready for the autumn season after revealing the return of its famous pumpkin spice latte to the menu.

It was 21 years years ago, back in aught-3, on a day that should go down in brand marketing history, when Starbucks introduced the Pumpkin Spice Latte. The move set off a fall beverage revolution. Now, virtually every shop that sells coffee — from 7-Eleven to indie roasters — offers some version of the PSL or other fall-flavored drinks.
