We are almost completely ignorant of the mechanisms that cause the sugar solution-the sap--to flow, although we do know that both positive and negative pressures develop in the tree, with sap moving both up and down. The making of maple syrup is essen tially the process of getting rid of ex cess water by rapid evaporation. If maple sap consisted only of water and sucrose, boiling it down would merely result in a caramelized syrup tasting much like Karo syrup or caramel candy. Sap, however, contains small amounts of calcium, potassium, phos phate and sodium ions which, al though nutritionally insignificant, may contribute to the taste of the syrup. There are also a variety of or ganic compounds including sucrose, invert sugars, amino acids and small amounts of citric, malic and other acids that make the sap slightly acidic. Equally important, there are minute amounts of phenolic compounds, par- 10 •• sugarhouse is shrouded in a steamy fog. Eventually the liquid approaches the "finishing point"-an ephemeral state the experienced sap maker can discern by the look of the boiling liquid, the color, and the pattern of bubbling. A thermometer also hdps: The liquid is taken off when its boiling point is reached. A hydrometer, regis~ tering the liquid's density, is also used. The finished syrup is drawn off and strained before bottling. If, instead, it is boiled further, the syrup reaches a higher temperature, becomes more concentrated and becomes, finally maple sugar candy. Since the composition of each batch of sap differs, so must its processing. In general, the early runs of sap pro duce the light-colored. aromatic "Fancy" grade of syrup.
