Understanding the USDA Almond Grading System
Almond quality and grading in the United States are regulated by the U.S. Department of Agriculture (USDA). These grades set minimum standards and tolerances for various quality factors, including visual appeal, whole kernels, mechanical damage, and presence of foreign material. The grading process ensures consistency and quality for both consumers and industrial applications. It is important to note that these are minimum standards, and a supplier may offer products with even more rigorous specifications.
The key factors considered during grading include:
- Whole Kernels: The percentage of unbroken almond kernels.
- Doubles: The percentage of kernels that grew as two almonds joined together.
- Chips and Scratches: The degree of mechanical injury to the kernel surface.
- Split and Broken Kernels: The percentage of almonds that are less than a complete whole kernel.
- Foreign Material: Any non-almond elements mixed with the batch.
- Other Defects: Includes damage from gum, mold, or shriveling.
- Serious Damage: Indicates decay, rancidity, or insect injury.
Choosing the Right Almond Grade for Your Application
Your specific use case dictates which grade provides the best value. What might be an excellent snacking almond is likely an unnecessary expense for making almond flour.
Snacking and Premium Retail: U.S. Fancy & U.S. Extra No. 1
For applications where visual perfection is critical, such as premium packaged snacks or chocolate-covered almonds, the top grades are ideal.
- U.S. Fancy: This is the highest grade, with the lowest tolerance for all defects. These are whole, clean, well-dried kernels with minimal chips, scratches, or other imperfections, ensuring the most attractive and uniform product. This grade is not widely available and often comes at a higher price point.
- U.S. Extra No. 1: A very high-quality grade, similar to Fancy, but with slightly more leniency for defects. It provides an excellent appearance and is a common choice for products where visual appeal is important but perfection isn't strictly necessary.
Baking, Roasting, and Food Service: U.S. No. 1 Supreme
This grade is a workhorse in the food industry, offering a balance of quality and cost.
- U.S. No. 1 (often called Supreme): This grade is widely used for whole almond applications like roasting, blanching, and inclusion in baked goods. It allows for a higher percentage of doubles and chips than the top two grades, making it more affordable for uses where appearance is not the sole priority.
Processing and Ingredients: U.S. Select & Standard Sheller Run
When almonds are destined for further processing, such as grinding into flour or paste, the cosmetic imperfections of lower grades are irrelevant.
- U.S. Select Sheller Run: A mid-quality grade suitable for industrial applications where almonds are incorporated with other ingredients. It has higher tolerances for chips, scratches, and broken kernels.
- U.S. Standard Sheller Run: The lowest quality grade for whole kernels, with the highest allowances for cosmetic defects and broken pieces. This is the most economical choice for making almond flour, paste, or for blending into products where they are not visible.
The Importance of Variety
Beyond the USDA grade, the almond variety also impacts the final product. Different varieties, such as Nonpareil, Carmel, and Mission, have distinct shapes, skin textures, and flavors. For instance, Nonpareil almonds have smooth, thin skins ideal for blanching, while Mission almonds have darker, wrinkled skins perfect for roasting. The ultimate taste and texture of an almond product depend on both the grade and the variety chosen. You can learn more about official standards from the USDA Almond Grades and Standards.

Conclusion: Choosing the Right Grade for You
There is no single "best" almond grade; the ideal choice is a strategic one, based on the specific application. For premium, visually-perfect results in snacking or gourmet dishes, U.S. Fancy or Extra No. 1 are the clear winners. However, if your almonds are destined for roasting, baking, or incorporation into other recipes, a U.S. No. 1 (Supreme) will provide excellent results at a more efficient cost. Finally, for almond flour or other processed ingredients, the more economical Sheller Run grades are a sensible and sustainable choice. By understanding the nuances of each USDA grade, you can make an informed decision that balances quality, appearance, and budget.
