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 . Maple trees are tapped by drilling holes into their trunks and collecting the exuded sap, which is processed by heating to evaporate much of the water, leaving the concentrated syrup . </P> <P> Maple syrup was first collected and used by the indigenous peoples of North America, and the practice was adopted by European settlers, who gradually refined production methods .
