The popular drink returns for the fall.

A staple of the fall season returns to Starbucks Tuesday. Expect lines at the drive thru as people have been waiting for 3 full seasons for the Pumpkin Spice Latte to return to the menu.

This is the 15th year that the baristas have brewed up the PSL in their shops. Researchers had to take a bite of pumpkin pie then take a sip of espresso to try to match the taste.

This wouldn't be a bad week to put some stock into Starbucks as the PSL is going to be very popular for the up coming weeks.
