(2) through (4) and the grade A color class in sub. (5), if applicable. The grade of a lot of maple syrup shall be determined by using the procedures in 7 CFR parts 52.1 – through 52.83. (2) Wisconsin grade a. No deviants for damage shall be labeled as Wisconsin Grade A. The grade designation Wisconsin Grade A may be applied to maple syrup that meets all of the following:
(a) Is not more than 68.9 percent solids content by weight (degrees Brix).
(b) Has good uniform color.
(c) Has good flavor and odor, and intensity of flavor (maple taste) normally associated with the color class in sub. 4.
(d) Is free from off flavors and odors considered as damage.
(e) Is free from cloudiness, turbidity, sediment, and is clean.
(3) Wisconsin maple syrup for processing (Processing Grade) Maple syrup bearing the grade designation Wisconsin maple syrup for processing (processing grade) shall be packed in containers holding at least 5 gallons (18.925 liters) and shall not be packaged in containers smaller than 5 gallons (18.925 liters) for retail sale. Processing grade syrup is maple syrup that meets all of the following:
(a) Fails to meet the requirements for Wisconsin grade A maple syrup.
(b) Possesses a fairly good characteristic maple taste.
(c) Is fairly clean and fairly free of damage, turbidity or cloudiness.
(d) May be in any color class and have any percent light transmittance.
(e) Has not more than 68.9 percent solids content by weight (degrees Brix).
(f) May contain off flavors and odors.
(g) May have a very strong taste.
(4) Substandard maple syrup. Maple syrup bearing the grade designation Wisconsin substandard is syrup that fails to meet the requirements in sub. (3) for Wisconsin processing grade maple syrup.
(5) Color classes for Wisconsin grade a maple syrup. The color class of Wisconsin grade A maple syrup is determined by the percent of transmittance of light at a wavelength of 560 nanometers through the syrup, as measured with a spectrophotometer using matched square optical cells having a 10 mm light path. The color value is expressed as percent of light transmission, as compared to analytical grade glycerol fixed at 100 percent. Percent transmittance is denoted by %Tc. Any method that provides equivalent results may be used to determine Wisconsin grade A maple syrup color class. Wisconsin grade A maple syrup color classes and corresponding flavor descriptors are shown in Table 1.
Table 1. Wisconsin Grade A Color Class Flavor Descriptor Percent light transmittance:
Golden Delicate At least 75.0
Amber Rich 50.0 – 74.9
Dark Robust 25.0 – 49.9
Very Dark Strong less than 25.0
