Quick Answer

U.S. honey grades are voluntary USDA scores out of 100: flavor and aroma 50, absence of defects 40, clarity 10. Grade A needs 90 points and at most 18.6% moisture. Color is classified separately on the Pfund scale, Water White to Dark Amber, and does not affect the grade. A jar labeled just honey must be only honey under FDA's 2018 guidance; blends with syrup must say so. Raw has no federal definition, so ask the producer how the honey was handled.

How Is Honey Color Classified?

How Is Honey Color Classified?

Honey color is measured in millimeters on the Pfund scale and sorted into seven USDA color classes, from Water White (8 mm or less) to Dark Amber (over 114 mm). Color is a description, not a grade: a dark honey and a light honey can both be U.S. Grade A.

Ranges below are from the National Honey Board reference guide.

  • Water White: 8 mm or less; Extra White: 9-17 mm; White: 18-34 mm
  • Extra Light Amber: 35-50 mm; Light Amber: 51-85 mm
  • Amber: 86-114 mm; Dark Amber: over 114 mm
  • Color follows the floral source: acacia honey and sage honey sit at the light end, buckwheat honey at the dark end
  • Darker honeys usually taste stronger
  • In lab assays darker honeys generally measure higher in antioxidant capacity (Illinois buckwheat 16.95 vs acacia 3.00 µmol TE/g ORAC in the NHB table); that is a lab number, not a health effect
How Is Honey Quality Tested?

How Is Honey Quality Tested?

Honey quality is judged by a USDA score for flavor and aroma, absence of defects and clarity, plus laboratory tests for moisture, HMF, diastase activity, pollen and residues.

The USDA extracted honey standard (effective May 23, 1985) scores honey out of 100 points: flavor and aroma 50, absence of defects 40, clarity 10 (clarity applies to filtered honey only). Grade A needs 90 points, Grade B 80 and Grade C 70. Grades are voluntary in the U.S.

  • Moisture: Grade A and B honey must be at least 81.4% soluble solids, i.e. at most 18.6% moisture (Grade C: 20.0%)
  • HMF (hydroxymethylfurfural) rises with heat and age; the Codex honey standard caps it at 40 mg/kg (80 mg/kg for tropical honey)
  • Diastase activity shows enzyme loss from heat and storage; Codex sets a floor of 8 Schade units (3 for honeys naturally low in enzymes)
  • Codex limits moisture to 20% for most honeys and 23% for heather honey
  • Pollen analysis (melissopalynology) helps confirm floral and geographic origin
  • Residue testing checks for pesticides and veterinary drugs

How Do You Read Honey Labels?

How Do You Read Honey Labels?

In the U.S., a jar labeled just "honey" should contain only honey; honey with added sugar or syrup must be named as a blend, such as "blend of honey and corn syrup."

That rule is from FDA's February 2018 honey labeling guidance.

  • "Raw" has no U.S. federal definition; the National Honey Board says it generally means not heated or filtered. A few states define it, e.g. Utah: as it exists in the hive or obtained by extraction, settling or straining, minimally processed and not pasteurized
  • USDA defines "filtered" honey as filtered until all or most fine particles, pollen grains and air bubbles are removed; "strained" honey keeps its pollen
  • A floral source on the label (for example "orange blossom honey") names the chief plant source
  • In the EU, from June 14, 2026, a honey blend must list every country of origin in descending order of weight with each country's percentage (FSAI summary of Directive (EU) 2024/1438)
  • UMF and MGO numbers apply only to manuka honey
How Do You Spot Fake or Adulterated Honey?

How Do You Spot Fake or Adulterated Honey?

You cannot reliably spot syrup-adulterated honey at home: water, flame and thumb tests do not detect syrup, and only laboratory analysis can. The practical warning signs are a price far below other honeys of the same variety and a seller who cannot name where the honey was produced.

Adulterated honey is usually cut with cheaper sugar syrups, or filtered so finely that its origin cannot be traced.

  • A price far below other honeys of the same variety is a warning sign
  • Ultra-filtered honey has had its pollen removed, which makes its origin hard to trace
  • Crystallization alone does not prove a honey is pure, and staying liquid does not prove it is fake
  • Ask the seller where the honey was produced and how it was processed
  • Buy from producers or packers who can name the source of their honey

What Honey Certifications Should You Look For?

Each honey certification verifies one thing: USDA Organic the organic regulations, True Source Certified a packer's supply chain and origin traceability, the Non-GMO Project its own standard, and Fair Trade the prices and conditions paid to beekeepers.

USDA Organic
Certified under the USDA organic regulations, which have no bee-specific section; certifiers often follow the National Organic Standards Board's 2010 apiculture recommendation, including a 1.8-mile organic forage zone
True Source Certified
Third-party audit of a packer's honey supply chain and origin traceability
Non-GMO Project
Verified against the Non-GMO Project Standard
UMF (Unique Manuka Factor)
Manuka-only grade from the UMF Honey Association covering marker compounds including methylglyoxal
MGO Rating
Methylglyoxal content of manuka honey in mg/kg as measured by the brand or its lab
Fair Trade
Third-party standard for prices and conditions paid to beekeepers

What Are Smart Tips for Buying Honey?

Buy from local beekeepers when you can, ask where the honey is from, how it was processed and when it was harvested, and treat a price that seems too good to be true as a warning sign.

  • Buy from local beekeepers when possible - freshest honey, supports local agriculture
  • Ask questions: Where is it from? How is it processed? When was it harvested?
  • If the price seems too good to be true, it probably is
  • Look for single-origin honey rather than blends for distinctive flavors — try sourwood honey for complex Appalachian spice notes, tupelo honey for unique Florida wetland terroir, or orange blossom honey for citrus-floral character

Frequently Asked Questions

How is honey graded?

In the U.S., the voluntary USDA standard scores honey out of 100 points: flavor and aroma 50, absence of defects 40 and clarity 10. Grade A needs 90 points and at least 81.4% soluble solids (at most 18.6% moisture). Color is classified separately on the Pfund scale, from Water White to Dark Amber, and does not change the grade. For example, acacia honey is usually very light and buckwheat honey dark amber.

How can you tell if honey is real or fake?

Not reliably at home. Water, flame and thumb tests cannot detect added syrup, and crystallization is not proof either way: high-glucose honeys like clover honey set fast, while acacia honey and tupelo honey stay liquid much longer. Adulteration is found by laboratory analysis. Buy from producers who can tell you where the honey came from, and be wary of prices far below the norm for the variety.

What does "raw" mean on a honey label?

There is no U.S. federal definition of raw honey. The National Honey Board says the term generally means honey that has not been heated or filtered. Some states define it in law; Utah, for example, defines raw honey as honey as it exists in the hive or obtained by extraction, settling or straining, minimally processed and not pasteurized. Ask the producer how the honey was handled.

Is organic honey really organic?

It is certified under the USDA organic regulations, but those rules have no bee-specific section. Certifiers often follow the National Organic Standards Board's 2010 apiculture recommendation, which calls for a 1.8-mile organic forage zone around the hives. Bees can fly farther than that, so organic honey describes how the hives are managed and where they sit, not every flower the bees visited.

Which honey varieties should I choose for different quality goals?

Choose by flavor and texture. For a mild everyday honey, clover honey or a local wildflower honey. For honey that stays liquid, acacia honey or tupelo honey. For strong, dark flavor, buckwheat honey or chestnut honey. For any of them, a producer who can name the source and harvest is worth more than a label claim.

Sources and Updates

Updated : Corrected the Pfund color classes to the seven USDA classes and explained that color does not set the grade; added the USDA scoring (50/40/10 points, 18.6% moisture for Grade A); replaced the unsupported claim that raw means not heated above 118°F with the National Honey Board and Utah definitions; added FDA's 2018 blend-labeling rule and the EU origin-labeling rule that applies from June 14, 2026; corrected the organic and certification descriptions; removed therapeutic manuka wording.
