Since it took a while to gather enough to justify boiling it down, I have been briefly boiling and then freezing the sap until I had a little over nine gallons. Then I fired up the woodstove evaporator in the back yard and tended it late into the night (click on the video). Last night I finally finished the syrup by boiling it on the kitchen stove until it reached the correct specific gravity which I measured with a hydrometer.
Once it was officially syrup, I filtered it for bottling by pouring it through a special wool syrup filter. This proved to be the least fun step of the entire process. Because I had so little syrup, it was difficult to keep it hot enough for it to easily flow through the cloth. By 2am I finally managed to get the result bottled as you can see in the photo.
In the end, I only got 16 oz. of syrup from the original 9.1 gallons of sap. By my calculation that means the sugar content of the sap was originally 1.07%. That is unfortunately about half that of a typical sugarbush of proper sugar maples. At that rate, I will need to boil down 73 gallons of sap to get one gallon of syrup. I assume that means that my planned tree identification exercise next summer will reveal that we have Red and Silver maples.
Nonetheless, the resulting syrup is light amber and very tasty. I passed out samples this morning and everyone was surprised that the taste was a more creamy vanilla-caramel than the expected standard maple flavor. Aidan was ready to haul out the griddle and fire up the stove for a pancake breakfast. I told him that we may wait a while before cracking that bottle open. It took too much work to make it and I just wanted to put it somewhere prominent and occasionally hold it up to the light to admire the maple magic.
