Maine Maple Sunday is an annual tradition held on the fourth Sunday of March where thousands of Mainers visit sugarhouses across the state to see the maple syrup harvesting process and sample the new syrup. It began 30 years ago when five sugarmakers sought to promote the industry and has since grown significantly. Today most sugarmakers use plastic tubing and vacuum pumps rather than buckets to more efficiently collect sap from their 1,000+ taps. Visiting a sugarhouse on Maine Maple Sunday has become a celebration of spring where people can learn about maple syrup production and sample various maple products.
