Maple sap rises in the Sugar Maple (Acer saccharum) trees in late Winter. Sap is collected usually in March when temperatures are above freezing in the day and below freezing at night. Early season “sap runs” traditionally produce the finest maple flavors.
It takes approximately 40 gallons of sap to make just 1 gallon of syrup. The collected sap is boiled to evaporate the water and concentrate the “liquid gold” into maple syrup form.
