How to make Birch Syrup. I have made Maple and Box elder syrup but this video shows you how to make Birch Syrup from the collected sap. This was an interesting project, the sugar in the Birch is not the same as in the Maple tree family. This sugar can be used by diabetics. Birch is Fructose while the Maple family is all Sucrose. This makes the process in rendering the sap into syrup a bit different as this video shows. The end product? you’ll have to watch to find out. Thank You.
