In maple country, it seems like everyone has a favorite syrup grade. Mine is U.S. Grade A dark amber. But soon, I’ll have to figure out how my favorite grade of the past jibes with a new system that several Northeastern states plan to adopt in the next few years, and that other states – as well as Canada – are also considering.
It turns out that, at least in New York, Vermont, and Maine, my favorite amber will soon be called either Grade A Amber, Rich Taste or Grade A Dark, Robust Taste, depending on which end of the amber spectrum I prefer. Lighter syrups tend to have more delicate flavors, while darker ones are more intense – a relationship on which the old maple syrup labels, that described color only, relied.
So why doesn’t all syrup taste the same? Sugars in maple sap undergo a series of changes during collection and processing that influence both color and flavor. “The most important determinant of what flavor develops in syrup are the reactions that occur when heat is applied as we process sap into syrup in the evaporator,” explained Abby van den Berg, a researcher at the Proctor Maple Research Center at the University of Vermont. » Continue Reading.
