Starbucks fall menu in 2020, including the Pumpkin Spice Latte (PSL), was launched on August 25, 2020. This was the earliest ever recorded return of the Pumpkin Spice Latte, starting the fall season two Tuesdays before Labor Day that year.
For comparison, in 2025, the Starbucks fall menu including the Pumpkin Spice Latte was announced to launch on August 26, which aligns with their more traditional timing closer to the end of August.
So, the 2020 fall menu release, which included the Pumpkin Spice Latte, took place on August 25, 2020.
