If you like a stronger robust flavor, you will prefer Grade B and if you like a delicate, light maple flavor, you'll prefer Light or Medium Amber. As with wine, the purpose for which the syrup is intended may dictate the grade of choice. When cooking and baking the stronger Grade B is often selected. Yet, on pancakes many people opt for medium to dark Amber. There are five grades, and as a rule the darker the color, the stronger the maple flavor.
Flavor is specific yet much more difficult to judge.
Someone with an experienced maple palate carefully tests the flavor. The state of Vermont is known for its strict guidelines and Coombs Vermont Gourmet's syrup is tested frequently by the State. In addition, Arnold Coombs randomly tests his syrup frequently. Maple is a natural sweetener with great versatility. Each grade has its virtues.
