How is Bulk Maple Syrup Made?
Maple syrup has been delighting the palate since indigenous people in North America first concentrated the slightly sweet sap of the sugar maple tree. Maple syrup is made in the springtime. To get the sap, a hole, 1/4 inch in diameter and about 1 ½ inches deep, three feet up from the ground is drilled into the tree. When a warm day follows a freezing night, the sap flows within the tree and out to our spout. Typically, the sap is a clear, slightly sweet liquid containing about 1-4% sugar. On average, it will take about 40 gallons of sap to produce one gallon of maple syrup.Read More »
The sap is then boiled. An evaporator is where the boiling of the sap takes place. Stainless steel pans sit atop an arch, or firebox, where firewood creates an intense, hot fire.
As the water in the sap evaporates, the sap thickens and as the sugar caramelizes it looks like hundreds of golden bubbles in the front pan. As the water is boiled off, the liquid becomes sweeter and more concentrated. This is when the boiling sap turns a rich golden color. When it reaches 219°F/103.8°C (66.5 brix), it has become maple syrup.
