What is the USDA Honey Grading System?
The United States Department of Agriculture (USDA) offers a voluntary grading system for extracted honey, classifying it into four grades: Grade A, Grade B, Grade C, and Substandard. This system is used by producers and packagers to certify their honey based on a scoring process that evaluates key physical characteristics. It is important to note that this grading system does not evaluate or account for the honey's floral source, authenticity, nutritional value, or regional origin. Instead, it focuses on attributes that affect a honey's cosmetic appearance and general purity.
How is Honey Scored?
The USDA grading process assigns points based on four primary factors:
- Moisture Content: Both Grade A and Grade B honey must have a moisture content of no more than 18.6%. Lower moisture content is generally desirable as it prevents fermentation.
- Absence of Defects: This assesses how free the honey is from foreign matter like bee parts, comb fragments, or foam. Grade A requires the honey to be “practically free” of defects, while Grade B requires it to be “reasonably free”.
- Flavor and Aroma: This criterion judges how characteristic the honey's flavor and aroma are for its declared floral source, and that it is free from off-flavors like fermentation or chemicals. Grade A honey must have an "excellent" flavor, whereas Grade B must have a "good" flavor.
- Clarity: Specifically for filtered honey, this factor measures the presence of air bubbles, pollen grains, or other fine particles. A clearer appearance scores higher points. Strained honey, which is less processed, does not receive points for clarity but is evaluated on other factors.
The Differences Between Grade A and Grade B Honey
While the 10-point difference in minimum score might seem small, it represents meaningful distinctions in the honey's quality and characteristics. Grade A honey represents the highest standard for commercial honey, while Grade B is a perfectly acceptable and high-quality product, often with a more pronounced character.
- Taste Profile: Grade A honey is known for its mild, sweet flavor and a cleaner, more delicate profile that enhances other ingredients without overpowering them. Grade B honey, conversely, typically has a more robust, complex flavor profile. This can make it a better choice for marinades, glazes, or dishes where a stronger honey taste is desired.
- Clarity and Defects: The primary differentiator is the level of visual perfection. A Grade A filtered honey will be exceptionally clear, with minimal suspended particles or foam. A Grade B honey may have slightly more cloudiness or a few visible fine particles, but it remains a high-quality product.
- Processing: To achieve the high clarity and defect-free standards required for Grade A (especially the filtered style), honey is often more extensively processed. This can involve extra filtration and gentle heating. While necessary for high grades, some enthusiasts prefer the minimally processed nature of a raw, strained honey, which might fall into Grade B or even C, as it retains more pollen and natural compounds.
Grade A vs. Grade B Honey: A Comparison
| Characteristic | U.S. Grade A Honey | U.S. Grade B Honey |
|---|---|---|
| Minimum Score | 90 points or higher | 80 points or higher |
| Flavor | Excellent, mild, and clean flavor | Good, often more robust and complex flavor |
| Clarity | Exceptional clarity (for filtered) | Reasonably clear (for filtered) |
| Defects | Practically free of any defects | Reasonably free of defects |
| Processing | Often more processed (e.g., filtered) to ensure clarity | Can be minimally processed (e.g., strained) |
| Ideal Use | Teas, delicate desserts, and light dressings | Baking, sauces, marinades, or robust beverages |
Beyond Grades: Other Factors Influencing Quality
For many honey connoisseurs, the letter grade is only one piece of the puzzle. Other characteristics offer a more complete picture of a honey's overall quality and profile.
- Floral Source: The flowers from which bees collect nectar are the most significant determinant of honey's color, flavor, and aroma. For example, light clover honey has a mild taste, while dark buckwheat honey has a strong, molasses-like flavor. The floral source also influences the presence of certain beneficial compounds.
- Color and Antioxidants: The color of honey, measured by the Pfund scale, is not part of the USDA letter grade. However, darker honeys generally contain higher levels of antioxidants than lighter ones. Research from the University of Illinois indicated that darker varieties can have up to 20 times the antioxidant content of lighter varieties. This means a Grade B dark amber honey could be nutritionally superior in antioxidants compared to a Grade A water white honey.
- Processing Method (Filtered vs. Strained): This is a crucial distinction not captured by the letter grade alone. Filtered honey (common in Grade A) is heated and forced through fine filters to remove all pollen and particles, resulting in a clear product that resists crystallization. Strained honey (often in Grade B or raw varieties) is only passed through coarse filters to remove large impurities, preserving pollen and other natural elements that can impact its cloudiness and flavor.
Which Honey is Right for You?
Choosing between Grade A and Grade B honey depends entirely on your needs and preferences. If your priority is a clean, mild flavor for your tea or a clear, uniform consistency for baking, a high-quality Grade A filtered honey will likely meet your expectations. However, if you are looking for a more robust flavor to use in a marinade, or if you prefer a less-processed product that retains more of its natural pollen and character, a Grade B or even a quality Grade C strained honey could be a superior choice.

Conclusion
In the end, deciding "is grade A or B honey better?" is not about one grade being universally superior to another. Grade A denotes exceptional cosmetic quality and uniformity, making it ideal for certain uses. Grade B is a high-quality product with less emphasis on perfection, often retaining more robust flavor characteristics. Ultimately, the best way to choose honey is to consider the floral source and processing method, aligning those factors with your specific culinary needs and taste preferences, rather than relying solely on the letter grade.
