Halpern’s Angus Beef Program

G-27 Specification

1 REQUIREMENTS

Beef carcasses certified under this specification shall meet the following requirements: 

a. Phenotypic or genotypic requirements of the American Angus Association’s (AAA) Live

Animal Specification;

b. Classed as Steer or Heifer carcasses only1;

c. U.S. Prime or Choice and have a minimum marbling score of Modest 01;

d. Less than 30 months of age with lean color, texture, and firmness, meeting the requirements for

A maturity in the U.S. grade it qualifies for1;

e. Medium or fine marbling texture1,2;

f. Ribeye Area (REA) of 10.0 to 16.0 square inches3;

g. Hot Carcass Weight (HCW) of 1,100 pounds or less4;

h. Fat Thickness (FT) of 1.0 inch or less5;

i. Moderately thick or thicker muscling and tend to be at least moderately wide and thick in

relation to their length6

;

j. No hump exceeding 2 inches in height7;

k. Practically free (not detracting from visual quality) of capillary rupture in the ribeye muscle;

and

l. Free of “dark cutting” characteristics.

2 CERTIFICATION

Carcasses to be examined for compliance with this specification shall be clearly identified and 

presented to an AMS grader for certification. Certification procedures for identification, the removal 

of preliminary identification marks (or other methods of control) from non-qualifying carcasses, and 

1 Determined in accordance with the “Official United States Standards for Grades of Carcass Beef.” 2 Evaluated using the USDA-AMS-LS-SB-02 Marbling Texture card (included in the Official USDA Marbling Photographs.) 3

 REA is inclusive of the lower and upper limits and allows for one side to meet the standard to consider both eligible for certification. 4 Establishes a maximum allowable HCW of 1,100 lbs. as determined and applied to the carcass at the hot scale. *(If Kidney, Pelvic and 

Heart Fat is fully or partially removed and not accounted for in the final HCW, then HCW must be less than 1,075 lbs.) 5 FT is to be determined at the 12th rib and represent solely an evaluation of subcutaneous fat over the ribeye at a point 3⁄4 the lateral 

length of the eye muscle from the backbone. If the actual FT over the ribeye has been altered due to a hide pull, gouge, trim, or other 

irregularity, a predicted line shall be determined along the curvature of the ribeye to establish an accurate prediction of unaltered fat 

thickness at the 12th rib surface. FT may be determined on either side of the carcass with at least one side meeting the standard to 

consider both eligible for certification. 6 Muscle thickness is evaluated by averaging the thickness of the various parts, considering not only the proportion of each part of the 

carcass but also the general value of each part. Superior muscle thickness implies a high proportion of meat to bone and a high 

proportion of the weight of the carcass in the more valuable parts.

7 Measured from a line formed by the extension of the top line (including the fat) and measuring the lean muscle (excluding the fat) 

perpendicular to that line in the center of the hump.
