More restaurants are launching their limited-time pumpkin spice and fall menu items earlier than before. Starbucks, Dunkin', IHOP, and Krispy Kreme have already released their pumpkin spice and fall menus for this year, with Starbucks launching on August 24th and Dunkin' first on August 16th. Cold drinks with pumpkin are popular in August when many people are still hot and seeking cold drinks.
