Did you know that you can buy a jug of Dunkin' Pumpkin Spice Swirl syrup on Amazon and eBay? It's also apparently pumpkin spice season across the land already, so there are plenty of ways to satisfy your pumpkin spice urge, even though fall is still weeks away. Later the same afternoon, I noticed a Facebook post from my daughter-in-law with a pumpkin spice cold brew in hand. I began to wonder how much Pumpkin Spice Swirl syrup Dunkin' customers from Maine to Massachusetts and out to Vermont, New Hampshire, Rhode Island, and Connecticut will consume in the coming months. "Based on these factors, Dunkin' locations across New England consume an estimated 420,000 to 560,000 gallons of pumpkin spice swirl syrup every fall season."
