The USDA syrup grading system uses five different maple grades. Three grade A's; Grade A Light Amber, Grade A Medium Amber, Grade A Dark Amber and two darker syrups, Grade B and Commercial Grade. These grades have upper and lower limits for color and flavor. As a rule, the darker the color, the stronger the flavor. Contrary to popular belief, maple syrup grades do not indicate which syrup is better, but is simply an indication of color and strength of maple flavor. Individual preference for a particular grade of maple syrup is similar to that of the wine consumer; some people prefer reds, some whites, some blush and so on. These similarities extend to other agricultural food products such as olive oil where extra virgin would be similar to light amber maple syrup; the first out - and then darker as the season progresses.
