Maple

"Acer is a genus of trees and shrubs commonly known as maples. Maple syrup is a syrup made from the sap of maple trees. In cold climates, these trees store starch in their trunks and roots before winter; the starch is then converted to sugar that rises in the sap in late winter and early spring. It has a sweet, distinctive flavour with hints of caramel and toffee that make it unique and difficult to put into words. Agriculture Canada have done their best by developing a 'flavour wheel', detailing 91 distinctive flavours that can be present in maple syrup."
