U.S. Grade No. 1 consists of grapes of one variety which are well colored, mature, not crushed, dried, or soft; which are free from mold, decay, berry moth injury, and from serious damage caused by russeting, hail, freezing, mildew, other disease, insects, or other means.
U.S. No. 2 consists of grapes which meet the requirements and tolerances of U.S. No. 1 grade except that the grapes need be only fairly well colored and except that not more than 3 percent shall be allowed for dried berries or those affected by berry moth.
Unclassified consists of grapes which have not been classified in accordance with any of the foregoing grades. The term "unclassified" is not a grade within the meaning of these standards but is provided as a designation to show that no grade has been applied to the lot.
