Many years ago, 1970s, when I had a coal stove I noticed that the fresh logs from my Norway maple
gave off a maple smell. Sooo-I tapped the trees-drilled a 1/2 inch hole, inserted one end of a plastic tube and the other end into gallon milk jug. Sap flowed freely and I evaporated it in a shallow pan on the wood stove. I taped the tube tightly around the milk jug to keep out ants. It did produce a sweet, faintly maple tasting syrup but of course these were not sugar maples. It takes a long time and a lot of fuel so would not be practical without a cheap source of heat. I did it for a couple of years--it was a great conversation piece. I stopped when I gave up the coal stove. It was fun though.
