A few years ago, I tapped two maple trees on my property, collected sap, and boiled it outside on a single-burner hotplate to make syrup. With a ratio of 40 gallons of sap needed to create one gallon of syrup, I ended up with about eight ounces of maple syrup—enough for a couple of pancake breakfasts.
It was a classic situation of the effort not equaling the reward.
But over this past weekend I had an opportunity to assist with a real maple sugaring operation because Owen was short a helper during the height of the short sugaring season, which typically lasts no more than six weeks, a period when freezing nights give way to warmer days, and the sap flows in the trees.
My experience at home in maple sugaring helped me not at all. Here in the forests of Connecticut is a real operation: 400 tapped trees, a network of tubing that uses a vacuum process to deliver the sap into two large tanks, a reverse osmosis machine that removes some of the water from the sap and increases its sugar content allowing for less boiling time, and a plethora of other machinery and operational procedures that results in a sweet, flavorful maple syrup.
The evaporator that boils the sap contains stainless steel pans, a firebox, and floats that manage the flow of sap. The raw sap travels from the holding tank to the rear evaporator pan and thickens as it moves toward a front pan. The syrup is ready when it reaches 220 degrees and a concentration of 66.9% sugar. It is then filtered and fed into a heated canning pan where it must maintain a temperature of about 195 degrees while being bottled.
The entire process was a lot more complex than I realized. You have to measure sugar density during the reverse osmosis process. You have to regularly stoke the firebox with wood to keep an intense heat on the boiling sap. You have to take remedial action if the sap begins to foam up while boiling. If you draw out the syrup from the evaporator and the sugar concentration isn’t just right, you have to pour it back into the evaporator. The filtering system can leak. The temperature can fall or rise in the canning pan.
Outside, snow fell. Inside the sugaring shack, the temperature was warm. We moved in and out as we worked. Not everything went smoothly, but Owen expertly handled each adverse event that came up, and the operation continued without interruption. I mostly carried in wood, fed the fire, and bottled and boxed the finished syrup. Also participated in a lot of taste tests.
The real pleasure of the day for me was serving in the role of an assistant to my son. He was the professional, I was the helper. He had the knowledge, I learned from him. This was one of those “passing of the torch” moments when you are reminded that your child has become a fully-formed, capable, and responsible adult. It’s both a wistful and joyous transition, as quick and short-lived as maple sugaring season, and it’s what every parent hopes for.
Pass the torch—but also, pass the syrup. Some of the finest I’ve ever tasted.
