There is one grade of maple syrup not commonly known to, or sold to, the retail buying public. Maple syrup Grade C (commercial) is sold only in bulk (40 gallon barrels) to industrial producers of maple flavored products. Any food product claiming to be flavored with real maple syrup, ie: maple flavored bacon, hot and cold maple flavored cereal, imitation “maple” syrup etc., will use commercial grade syrup as an additional additive for flavoring.posted by jessamyn (staff) at 8:28 AM on December 10, 2010 [1 favorite]
Grade C (commercial) is the last syrup made during the sugaring season. It is very dark and may have an off taste, a burnt taste or even be fermented. Although some grade C maple syrup may have a good flavor, it is not to be repackaged in retail containers.
The real thing's less entertaining, but I guess it had to be.
