ATCP 85.02
ATCP 85.02 Procedure for determining Wisconsin butter grades. The Wisconsin grade of butter shall be determined on the basis of a representative butter sample, tested and rated according to the following sequential steps:
ATCP 85.02(1)
(1) Each applicable flavor characteristic of the sample shall be identified under
s. ATCP 85.04 (1) (a), and the relative intensity of the characteristic shall be determined under
s. ATCP 85.04 (2). A preliminary letter grade designation is given to the butter sample on the basis of the sample's flavor characteristic and intensity, using the table under
s. ATCP 85.05 (1). When more than one flavor characteristic is discernible in a sample of butter, the flavor classification of the sample shall be established on the basis of the flavor that carries the lowest grade.
ATCP 85.02(2)
(2) Each applicable body, color and salt characteristic of the sample shall be identified under
s. ATCP 85.04 (1) (b),
(c) and
(d), and the intensity of the characteristics shall be determined under
s. ATCP 85.04 (2). Based on body, color and salt characteristics, and the intensity of the characteristics, the sample shall be given any requisite disratings, using the table under
s. ATCP 85.05 (2).
ATCP 85.02(3)
(3) The final Wisconsin butter grade for the sample shall be established on the basis of the flavor classification, subject to disratings for body, color and salt characteristics, using the tables under
s. ATCP 85.05 (2),
(3) and
(4). When disratings for body, color and salt characteristics exceed the allowable amount for any flavor classification, the final Wisconsin grade shall be lowered accordingly. Final Wisconsin butter grades shall meet the specifications set forth under
s. ATCP 85.03.

ATCP 85.03
ATCP 85.03 Specifications for Wisconsin butter grades. Specifications for final Wisconsin grades of butter are set forth in this section. Compliance with grade specifications is determined according to the procedure set forth under
s. ATCP 85.02. The flavor, body, color and salt characteristics specified or allowed for butter grades under this section have the meanings set forth in
s. ATCP 85.04 (1). The degrees of intensity for a specified or allowed butter characteristic under this section are set forth in
s. ATCP 85.04 (2).
