How Maple Syrup is Made. The maple syrup production process gets its start from one of natureâs true phenomena. In springtime, when the nights are still cold, water from the soil is absorbed into the maple tree.bout 40 liters (10.5 gallons) of sap boil down to one liter (about .25 gallons or one quart) of pure maple syrup. For other maple products â butter, taffy, or sugar â the sweet syrup is further boiled in the evaporator to the temperature necessary to produce the different types of maple products.
