You can get sugar syrup from just about any maple. Just that the sugar maples in North America are the best species for it when it comes to sap, harvest season, and taste as maple syrup is surprisingly complex when it comes to the chemical composition of its flavor. There is some written evidence that the ancient Greeks produced sugar syrup from maples though it was used as a medicine. Aristotle mentioned it for example. There wouldn't be any problem planting Sugar Maples in say Scandinavia or the foothills of the Alps in Germany, Austria, and France. It is just that sugar beets grow quicker and are easier to process than Sugar Maples. Europeans never really acquired a taste for maple syrup like the Canadians and Americans did.
