Dunkin' Donuts reported a 3 percent increase in sales in the week following the launch of its pumpkin spice latte menu. This is the first time that Dunkin' has seen a sales increase during the pumpkin spice latte season since 2020.The popularity of the pumpkin spice latte is likely due to a number of factors. First, the drink is associated with fall, a time of year that many people enjoy. Second, the pumpkin spice latte is a unique and flavorful drink that is not available year-round. Finally, the pumpkin spice latte has been heavily marketed by coffee chains in recent years, which has helped to increase its popularity.While pumpkin spice latte sales have been strong this year, it is important to note that the overall market for pumpkin spice products is declining. According to NielsenIQ, sales of pumpkin spice products fell by 1.5 percent in the yearlong period ended in July 2023. This is the second consecutive year that pumpkin spice sales have declined.The decline in pumpkin spice sales is likely due to a number of factors, including consumer fatigue and the increasing availability of pumpkin spice products throughout the year. However, the pumpkin spice latte remains a popular seasonal drink, and it is likely to continue to drive sales for coffee chains in the years to come.
