Crop Quality & End Uses
The hardest of all U.S. wheat classes, U.S. durum has a rich amber color and high gluten content. Hard Amber Durum (HAD) set the “gold standard” for premium pasta products, couscous and some Mediterranean breads. Durum has a high protein content of 12.0% to 15.0% (12% mb), yellow endosperm and white bran.
For the miller, durum is a large, very hard kernel with the potential for very high extraction of high quality, low ash semolina that is ideal for fine pasta. Desert Durum® is harvested and shipped at a very low moisture content, an advantage to millers that contributes to efficient transportation costs and high extraction rates.For consumers of pasta, couscous and Mediterranean breads, durum helps deliver excellent color and texture.
Where is U.S. durum grown?
Durum is the fifth largest class of wheat grown in the United States. Northern durum is grown primarily in the North Central region (North Dakota and Montana) and shipped via Gulf, Great Lakes and Pacific ports, while Desert Durum®, is grown primarily under contract in the desert Southwest (Arizona and California) and shipped via the Gulf or West Coast.

2023 U.S. Durum Crop Quality Data Highlights

Strong features of the 2023 Northern Durum crop include higher protein, strong grades, low damage, good test weights, and sound kernel characteristics. Diligent contract specifications will help manage some variable quality parameters, especially vitreous kernel content. The crop shows increased gluten strength and end-use characteristics similar to an average crop. Overall, this crop will meet the needs of customers.

U.S. Durum Subclasses
Under the Official United States Standards for Grain, U.S. durum wheat is divided into the following three subclasses based on vitreous kernel content:
- Hard Amber Durum (HAD) – at least 75% hard, vitreous kernels of amber color
- Amber Durum (AD) – between 60-74% hard, vitreous kernels of amber color
- Durum (D) – less than 60% hard, vitreous kernels of amber color
U.S. Durum Sample Collection and Analysis
NORTHERN DURUM
Official grade and non-grade factors were determined on 60% of samples. The remaining tests were conducted on 6 composite samples categorized by growing region for Northern Durum.
- Samples were collected in two states by USDA National Agricultural Statistics Service (NASS) and state wheat commissions.
- Official grades were determined by Northern Plains Grain Inspection.
- Milling and wheat and flour quality testing and analysis were conducted by The Durum Quality Lab at North Dakota State University.
DESERT DURUM®
Official grade and non-grade factors are determined on every sample collected. Production weighted results are reported.
- Samples were collected by California Wheat Commission Laboratory and Arizona Grain Research and Promotion Council.
- Official grades were determined by the USDA Federal Grain Inspection Service (FGIS) and Farwell Grain Inspection.
- Milling and wheat and flour quality testing and analysis were conducted by the California Wheat Commission Laboratory.
