Visual Grading Guide for Produce

Created with SARE support
2025

Wholesale buyers expect consistent quality, but clear grading standards are surprisingly hard for local producers to find. Without visual benchmarks, many farmers learn through trial and error, leading to unexpected rejections and lost income on delivery day.

To solve this problem, regional food hub The Good Acre in Saint Paul, Minnesota, developed the Produce Grading Guide with funding from a SARE grant. Designed specifically for specialty crop farmers entering wholesale channels, the guide uses detailed photos, crop information, and post-harvest advice to establish clear standards for growers, buyers, and technical advisers alike.

"Selling into wholesale markets requires consistent quality, but clear grading standards are not always easy to find," said Josh Bryceson, Director of Grower Support with The Good Acre. "We created this guide to make wholesale expectations easier to understand through photographs, crop-specific specifications, and practical guidance."
