Sugar Maples can run as high as a 3% sugar content to the sap. My Norway Maples are around 2%. I've read other types of Maples are also about 2%. You can tap Birch trees too, but they only have about 1% sugar. It takes about 45-50 gallons of sap for me to get a gallon of syrup with my trees. I have a big 4 gallon stainless steel pan I put on top of my wood stove and let it get most of the water out. Then finish reducing it in a sauce pan on the stove. If you let it go to far you get maple candy. If you wander off and forget about it, you get a house full of very maple smelling smoke and a pan of carbon atoms. Whoops. It thickens up pretty fast near the end. I make mine a little thinner than I did at first and just go by taste as when to stop now. You get better pancake mileage that way. I never thought of flavoring tobacco with it. I love cherry Cavendish, so I might have to try making a batch of maple.
