– It takes roughly 40 gallons of sap to make one gallon of maple syrup
– Maple sap is mostly crystal-clear water with about 2% sugar content.
– A typical sugaring season lasts 4 to 6 weeks. A pattern of freezing and thawing temperatures (below freezing at night and 40 – 45 degrees Fahrenheit during the day) will build up pressure within the tree causing sap to flow from the tap holes.
– Sugaring season ends when the warmer days of late spring cause the leaf buds to unfold.
– A tree needs to be about 40 years old (10 – 12 inches in diameter) to tap
– Some large maple trees in Vermont Sugarbushes are over 200 years old
