Should I put a USDA grade on my jam?
Updated

Almost certainly not. USDA grades for jelly and for preserves (jams) are voluntary, decades old, and can only be claimed after a fee-based inspection by the federal grading service [1][2]. Nothing requires them, and shoppers at a market or a specialty shop do not look for them. They are useful in a different way: the scorecards are a clear, published description of what a good jam or jelly looks and tastes like, and you can use them to judge your own batches. This page gives both scorecards, the point thresholds, and the few cases where a grade might matter.
Two standards, both from 1979 and 1980
USDA's Agricultural Marketing Service publishes grade standards under the Agricultural Marketing Act of 1946 for use by producers, buyers and consumers [1][2]. The two that matter here are:
- United States Standards for Grades of Fruit Jelly, effective September 3, 1979 [1].
- United States Standards for Grades of Fruit Preserves (Jams), effective January 4, 1980 [2].
These are the issues USDA posts today. They predate low-methoxyl pectin spreads, freezer jam and most of today's specialty market. They also have nothing to do with the FDA standards of identity, which decide whether you may call a product jam at all. A grade sits on top of the identity standard. The identity standard decides whether a product is jam; a grade scores how good that jam is.
The jelly scorecard
| Factor | Maximum points | What Grade A looks like |
|---|---|---|
| Consistency | 40 | "tender to slightly firm texture and retains a compact shape without excessive syneresis (weeping)" |
| Color | 20 | Characteristic of the juice, with a "sparkling luster or may be not more than slightly cloudy," free from dullness |
| Flavor | 40 | "good distinct flavor characteristic of the fruit or nonfruit ingredient(s)," free from caramelized or other objectionable flavors |
| Total | 100 |
Thresholds: U.S. Grade A at 90 points or more; U.S. Grade B at 80 or more; below that, Substandard [1].
All quotations are from the jelly standard [1]. Note that it covers nonfruit ingredients too, so a well-made herb or wine jelly can be scored against it.
The preserves (jam) scorecard
| Factor | Maximum points | What Grade A looks like |
|---|---|---|
| Consistency | 20 | Fruit "dispersed uniformly throughout the product," a "tender gel" or "no more than a very slight tendency to flow" |
| Color | 20 | Good color |
| Absence of defects | 20 | Practically free from defects |
| Flavor | 40 | Good flavor |
| Total | 100 |
Thresholds: U.S. Grade A at 85 points or more; U.S. Grade B at 70 or more; below that, Substandard [2].
The preserves standard allows a slightly softer set when the fruit is mostly whole or nearly whole, and for kinds such as apricot, cherry and strawberry it says the product must not look macerated or pureed [2]. It also requires a solids content of not less than 65 degrees Brix before a product can be graded [2], which matches the FDA floor described on what 65 percent soluble solids means.
Limiting rules: one weak factor caps the grade
Both standards have limiting rules. If any single factor scores in the Grade B range, the product cannot be graded above U.S. Grade B, whatever its total; if any factor scores as Substandard, the product is Substandard [1][2]. A strawberry jam with superb flavor and color but a runny set cannot be Grade A. That mirrors what customers do: one flaw is what they remember.
Why few small makers use grades
- You cannot claim one without inspection. The federal inspection service is "the only activity authorized to approve the designation of U.S. grades," and it works on a fee-for-service basis, either in-plant or by lot, under 7 CFR Part 52 [1][2]. Printing "Grade A" on your own judgment is not an option.
- Retail shoppers do not ask. Nothing in a farmers market or specialty shop sale depends on a grade. What sells there is the name, the flavor, the label and your story.
- They were built for institutional buying. The preserves standard even has a "Grade A for Manufacturing" that cannot be packed in containers smaller than a No. 10 can [2]. The standards' natural home is bulk sales to manufacturers and food service.
A grade might be worth asking about if you sell jam in bulk to a manufacturer, a school or government buyer, or a food service distributor whose specification calls for a U.S. grade. In that case the buyer will tell you, and the inspection fee is part of the cost of the contract.
Use the scorecard on your own batches
The standards earn their keep as a quality checklist. Score a jar from each batch on the jelly or preserves scorecard, write the numbers on the batch record, and you have a consistent way to compare this year's apricot with last year's, or one helper's batch with another's. A jelly that loses points for weeping points you to weeping jam and jelly; a consistency score that wanders from batch to batch points you to making every batch the same, which covers specs by weight and reading.
