Starbucks’ pumpkin spice latte returns August 26; why this seasonal drink still reigns supreme

Starbucks announces the return of its popular Pumpkin Spice Latte on August 26. The PSL, first launched in 2003, has become a fall tradition. The menu will also feature returning favorites and new items. The PSL's success is due to sensory science, limited availability, and marketing. It evokes feelings of warmth and nostalgia.
