Here is the misunderstanding that quietly costs vanilla buyers more money than any other: the grading system is not a quality ranking. It is a sorting system — based mostly on moisture and length — and treating it as a hierarchy means buyers routinely pay a premium for characteristics their application doesn't need, while overlooking the grade that would have delivered more flavor for less money. Once you understand what the letters actually measure, the right order becomes obvious.
Grade A, Grade B, and Grade C vanilla beans are not better or worse than one another — they are sorted by moisture, length, and appearance, not by flavor. Grade A is for direct use and presentation. Grade B is drier, cheaper, and often delivers more vanillin per dollar, making it the smarter choice for extraction. Grade C is for industrial-scale infusion. The best grade is simply the one that matches the job.
What Vanilla Grading Actually Measures
Grading was designed to sort beans for handling and appearance, not to rank aromatic quality. The criteria are physical: pod length, moisture content, flexibility, colour, sheen, and freedom from visible defects like splits and blemishes. Notice what isn't on that list — vanillin concentration, aromatic complexity, or anything else that determines how the bean actually tastes in your product.
This is why a "lower" grade can outperform a "higher" one. A short, dry, slightly blemished bean and a long, plump, flawless one can come from the same vine, the same harvest, and the same curing barn, and carry a nearly identical aromatic payload. One simply looks better in a jar. If your customer will never see the pod — because you're extracting, infusing, or grinding it — you are paying a premium for a photograph.
The Three Grades, Properly Explained
Grade A — Gourmet / Prime
Grade A beans are 15cm or longer, typically 30–35% moisture, visibly lustrous, and pliable enough to bend into a curl without cracking. These are the beans for direct use and visible presentation — scraping seeds into a custard, showcasing a whole pod in a display, packing retail jars, or any application where the bean itself is part of the experience. Price per kilogram is the highest of the three, and a meaningful share of that price is paying for moisture and visual perfection rather than additional flavour compound.
Grade B — Extract Grade
Grade B beans are shorter (typically under 15cm) and drier (often under 25% moisture). Here is the part most buyers miss: vanillin concentrates as moisture drops. Because you're purchasing by weight, a kilogram of drier Grade B beans can carry more actual vanillin by dry weight than a kilogram of higher-moisture Grade A from the same origin — while costing considerably less. For extraction, syrups, infusions, and anything where the pod is discarded after processing, Grade B is frequently the smarter buy, not the compromise one. It is the single most reliable way to improve your flavour-per-dollar without changing suppliers.
Grade C — Cuts & Splits
Grade C beans are split, cut, or cosmetically blemished during harvest or curing. These are appearance defects with no bearing on aromatic quality — and the increased surface area of a split pod actually causes it to extract faster than an intact one. For industrial extraction, large-batch infusion, or any high-volume application where visual perfection is irrelevant, Grade C offers the strongest cost efficiency available. Dismissing it as "low quality" is a category error: it's low cosmetic quality, which is not the same thing at all.
The Moisture Math That Costs Buyers Money
This deserves its own section because it's where the real money leaks. Vanilla is sold by the kilogram. Moisture is part of that kilogram. Water contributes nothing to flavour — but you pay full price for it. A lot at 35% moisture is, by definition, 35% water by weight. A lot at 25% moisture delivers proportionally more actual bean per kilogram purchased, and therefore more of the compounds you're buying the bean for.
None of this means high moisture is bad — Grade A's suppleness is exactly what makes it right for direct use, and beans that are too dry become brittle and lose aromatic volatiles. The point is narrower and more useful: if the pod is going to be discarded after extraction, moisture is a cost with no benefit. Buyers who internalise this stop defaulting to Grade A for extract production and immediately improve their economics without sacrificing a thing.
- Moisture % — confirms the grade claim and tells you how much of the weight is water
- Vanillin % — ask whether it's stated on a wet or dry basis; the two are not comparable
- Length range — the physical basis of the grade letter
- Origin / lot number — enables traceability and repeat ordering of the same profile
- Defect count — splits, blemishes, mould; relevant for Grade A, largely irrelevant for extraction
- Testing method — HPLC from an independent lab, not a number typed on a spec sheet
The Grade-Naming Problem Nobody Warns You About
There is no single global authority enforcing vanilla grade definitions. Different origins and exporters use different nomenclature — you'll encounter A/B/C, Gourmet/Extract, Prime, "black," "TK," "red," and various house systems, sometimes with overlapping or contradictory meanings. A "Grade A" from one exporter may not meet another exporter's Grade A specification at all.
The defence is simple and it is the most important habit in vanilla procurement: buy the specification, not the letter. Ask for moisture percentage, vanillin percentage with the measurement basis stated, length range, and origin — in writing, per lot, on a certificate of analysis. A letter is a marketing shorthand that varies by seller. Numbers on a COA are a contract. When you compare offers on specifications instead of grade letters, the entire market becomes legible, and the supplier who was quietly overcharging you becomes obvious.
| Grade | Length | Moisture | Best For | Relative Price |
|---|---|---|---|---|
| Grade A (Gourmet) | 15cm+ | ~30–35% | Direct use, pastry, retail, visible presentation | Highest |
| Grade B (Extract) | Under 15cm | Under ~25% | Extraction, syrups, infusions — best vanillin per dollar | Mid |
| Grade C (Cuts & Splits) | Variable | Variable | Industrial extraction, bulk infusion, high volume | Lowest |
We publish moisture content, vanillin percentage, and origin farm data on a certificate of analysis with every lot — because a buyer who can see the specifications can choose the grade that actually fits what they're making, rather than defaulting to the highest letter and hoping. Transparent grading isn't a courtesy. It's the only way a buyer can tell whether they're getting value.
Frequently Asked Questions
Is Grade A vanilla always the best choice?
No. Grade A is the best choice when appearance, moisture, and pliability matter — direct use in custards, retail packaging, or visible presentation. For extraction or infusion, where the pod is discarded after processing, Grade B typically delivers more vanillin per dollar spent because its lower moisture concentrates the flavour compounds you're actually paying for.
What do vanilla bean grades actually measure?
Physical characteristics: pod length, moisture content, flexibility, colour, sheen, and visible defects. Grading does not measure vanillin concentration or aromatic complexity, which is why a lower grade can carry an equal or greater flavour payload than a higher one from the same harvest.
Why is Grade B vanilla cheaper but sometimes higher in vanillin?
Because lower moisture concentrates the vanillin already present in the bean. Vanilla is sold by weight, so a kilogram of drier Grade B contains more actual bean — and therefore more vanillin by dry weight — than a kilogram of higher-moisture Grade A, even though Grade B costs less per kilogram.
Is Grade C vanilla low quality?
It's low cosmetic quality, not low aromatic quality. Grade C beans are split, cut, or blemished — defects of appearance that don't affect flavour. The greater surface area of split pods actually makes them extract faster than intact ones, which is why they're well suited to industrial extraction and bulk infusion.
Do all suppliers use the same vanilla grading system?
No, and this is a common source of costly confusion. There is no single global standard — origins and exporters use different systems (A/B/C, Gourmet/Extract, black, TK, red, and house schemes) with varying definitions. Always buy on the specification — moisture, vanillin percentage, length, origin, stated on a certificate of analysis — rather than trusting the grade letter alone.
