Thank you, Starbucks! PSL, barista-speak for the Pumpkin Spice Latte, is my favorite espresso drink at Starbucks. However, it is a seasonal drink, available only from late August to January. The reemergence of PSL signals the arrival of the fall season. Forget that we are still experiencing beautiful beach weather here in Southern California and that my tomatoes are producing like it’s the middle of August. When Starbucks says it’s fall, it’s fall, darn it!
