Origin tells you where your cacao came from.
Specifications tell you what it will do in your production.
These are different pieces of information. Both matter. But in a production context — a commercial kitchen, a food manufacturing facility, a chocolate atelier — the specifications are what govern performance. Fat content determines mouthfeel. Particle size determines dispersion. pH determines colour, flavour, and baking chemistry. Moisture content determines shelf life.
Most cacao buyers never specify these parameters explicitly. They order by origin, price, and organic status. The specifications arrive on a COA they may or may not read carefully. Production absorbs whatever variation exists. This guide changes that. It covers the six specifications that determine cacao performance in production, what each means for your specific application, how to read a COA as a production planning tool, and how to brief a supplier correctly so the cacao that arrives does what you need it to do.
Why Most Cacao Buyers Focus on the Wrong Specifications
Origin is important. But origin is an upstream determinant. It tells you the genetic potential and the post-harvest treatment of the cacao before it was processed. What arrives at your facility is a finished product — powder, butter, or whole beans — whose performance in your process is governed by measurable physical and chemical specifications.
A buyer who specifies 'fine flavour single-origin Peruvian cacao' without specifying fat content, particle size, and pH has defined the origin but left the three specifications most likely to affect their product's performance undefined.
The same origin, processed to different specifications, produces very different production outcomes. High-fat cacao powder from Peru's Piura Valley makes an exceptional single-origin hot chocolate. Standard-fat cacao powder from the same origin may not provide the richness the application needs. The origin is identical. The production performance is not.
The specification framework: there are six parameters that determine cacao performance in production. Fat content. Particle size. pH. Moisture content. Fermentation rate. And microbial quality. Each is measurable, specifiable, and directly linked to your production outcome. Each should be on your supplier brief before the order is placed — not discovered on the COA after delivery.
The table below summarises the six key production specifications, their target ranges, and what to watch for.
| Specification | Standard Range | Target for Premium | What It Affects | Red Flag |
|---|---|---|---|---|
| Fat content (cocoa butter) | 10–12% | 20–22% (high-fat) | Mouthfeel, viscosity, richness. Critical for hot chocolate and ganache. | < 10%: thin, dry mouthfeel. > 24%: unstable in some applications. |
| Particle size | 20–30 microns | 10–15 microns (fine) | Dispersion, texture, mouthfeel. Critical for beverages. | Above 30 microns: sandy texture, poor dispersion in cold liquids. |
| pH (natural) | 5.0–6.0 | 5.2–5.8 (controlled) | Flavour brightness, baking leavening, and polyphenol retention. | Below 4.8: over-acidic. Clashes with dairy and sugar. |
| pH (Dutch) | 6.8–8.5 | 7.0–7.5 (stable) | Colour depth, neutral flavour, stability in alkaline formulations. | Above 8.5: over-alkalised. Flat, soapy aftertaste. |
| Moisture content | < 5% | < 4.5% (premium) | Shelf life, clumping, mould risk, powder flowability. | Above 5%: elevated mould risk, reduced shelf life, caking. |
| Fermentation rate | ≥ 75% (commercial) | ≥ 85% (premium) | Flavour complexity, bitterness, astringency, and colour development. | Below 75%: flat, astringent profile that processing cannot fix. |
Cacao Fat Content — The Specification That Determines Mouthfeel and Viscosity
Cacao fat content — the percentage of cocoa butter remaining after pressing — is the single specification most directly linked to mouthfeel, richness, and viscosity in the finished product.
Standard cacao powder retains 10 to 12 per cent cocoa butter. High-fat cacao powder retains 20 to 22 per cent. This is a controlled processing decision, not a fixed characteristic of the origin.
What fat content affects by application
- Hot chocolate and speciality café beverages: High-fat cacao powder (20 to 22 per cent) produces measurably richer mouthfeel and better suspension in milk or water. Standard-fat powder can produce a thin, dry texture — particularly noticeable in premium café applications where mouthfeel is part of the product experience. If your hot chocolate tastes thinner than expected, low cacao fat content is the first specification to check.
- Ganache and chocolate couverture: Fat content affects viscosity and set time. Higher-fat cacao powder contributes more to the overall fat balance of a ganache. This can be an advantage or a liability depending on your recipe. Specify the fat content explicitly and adjust your recipe fat ratio accordingly.
- Baking applications: Standard-fat powder (10 to 12 per cent) is the norm for baking — cake, brownie, and biscuit applications where emulsification is handled by other fats in the recipe. High-fat powder is rarely necessary in baking and adds cost without proportional benefit in most formulations.
- Chocolate manufacturing: Fat content affects tempering behaviour and viscosity in production. Discuss your fat content requirements explicitly with your supplier if you're using cacao powder as a component in a manufactured chocolate product.
How to specify: State fat content as a range — '20–22 per cent cocoa butter' for high-fat, '10–12 per cent' for standard. Confirm this appears on the COA as a measured result, not just a product description.
Cacao Particle Size — The Specification That Determines Texture and Dispersion
Particle size is the specification most commonly ignored by buyers and most commonly responsible for disappointing beverage performance.
Standard cacao powder has a particle size of 20 to 30 microns. Fine-milled premium cacao powder reaches 10 to 15 microns. The difference is not visible. In a hot chocolate or cacao beverage application, it is immediately detectable.
What particle size affects
- Beverage dispersion: Fine-milled cacao powder dissolves cleanly in water and milk at 10 to 15 microns. Standard powder at 20 to 30 microns produces visible settling in cold liquids and incomplete integration in hot beverages — particularly noticeable in cold-brew or iced cacao preparations. If your powder sinks to the bottom of a warm drink within 30 seconds, particle size is the issue.
- Mouthfeel: Particles above 25 microns are detectable on the palate as a slightly sandy or gritty texture. Below 20 microns, the powder feels smooth. Below 15 microns, the texture is indistinguishable from dissolved liquid.
- Shelf life: A finer particle size slightly increases the surface area of the powder, which can accelerate fat oxidation if the powder is stored incorrectly. Properly sealed high-quality cacao powder at a fine particle size requires cool, dry, sealed storage to maintain quality.
- Colour development: Finer particle size produces slightly more intense colour in applications. Relevant for baking applications where the visual chocolate colour is part of the product.
How to specify: Request particle size as d90 or d50 measurement (the particle diameter below which 90 per cent or 50 per cent of particles fall). For premium beverage applications, specify d90 ≤ 20 microns. For standard baking, 20–30 microns is appropriate.
Cacao pH — The Specification That Determines Colour, Flavour, and Baking Chemistry
pH is the most consequential specification for applications involving heat, leavening agents, or dairy — which covers most food manufacturing contexts.
Natural cacao powder has a pH of 5.0 to 6.0. It is acidic. Dutch-processed (alkalised) cacao powder has a pH of 6.8 to 8.5. It is neutral to mildly alkaline. These are not interchangeable in production.
How pH affects colour
Alkalisation deepens cacao colour significantly. Dutch-processed powder produces the deep brown-black colour most consumers associate with rich chocolate. Natural cacao powder produces a lighter reddish-brown colour. If your product requires a dark, visually intense chocolate colour — commercial brownies, chocolate ice cream, dark chocolate coatings — Dutch-processed cacao powder delivers this reliably. Natural cacao in the same formulation produces a lighter, redder result that may not match consumer expectations.
How pH affects flavour
Natural cacao retains its original acidity and the full polyphenol profile. The flavour is brighter, more fruit-forward, with higher perceived acidity. Dutch-processed cacao has a mellower, rounder, more neutral chocolate flavour. The acidity is neutralised. The complexity is reduced. The flavour is more predictable across applications.
For a product where the cacao flavour profile is the feature — single-origin hot chocolate, fine chocolate — natural cacao powder preserves the character that makes the origin interesting. For a product where chocolate is a background note and consistency is paramount, Dutch-processed is appropriate.
How pH affects baking chemistry — the critical production point
Baking soda (sodium bicarbonate) requires an acidic environment to activate. Natural cacao powder at pH 5.0 to 6.0 provides this acidity and activates baking soda correctly in a recipe. Dutch-processed cacao powder at pH 6.8 to 8.5 does not reliably activate baking soda.
A recipe developed with natural cacao and baking soda will not rise correctly if Dutch-processed cacao is substituted without also substituting the leavening agent. This is the root cause of many unexplained baking failures when cacao suppliers are switched.
Natural cacao = baking soda (bicarbonate of soda) as leavening. Dutch-processed cacao = baking powder or modified leavening. Switching between the two without adjusting the rest of the formulation will produce incorrect results.
For health food and functional food applications making antioxidant or polyphenol claims, pH is a specification with direct regulatory implications. Alkalisation reduces polyphenol content significantly. Research consistently shows that Dutch-processed cacao retains markedly lower flavanol levels than natural cacao processed under the same conditions.
A product making polyphenol, antioxidant, or flavanol content claims should use natural cacao powder — not Dutch-processed. Using Dutch-processed cacao under a polyphenol claim creates a gap between the label and the product that is both commercially misleading and increasingly scrutinised by regulators.
Cacao Moisture Content — The Specification That Determines Shelf Life and Flowability
Finished cacao powder should have a moisture content below 5 per cent. Premium specification is below 4.5 per cent. This is the specification most commonly underspecified in purchasing briefs — and it has direct consequences for shelf life, production performance, and food safety.
What happens above 5 per cent moisture
- Caking and clumping: Above 5 per cent moisture, cacao powder begins to absorb ambient humidity and cake. Powder that has caked in transit or storage produces inconsistent dosing in production, affecting batch-to-batch consistency without any change to the recipe.
- Mould risk: Moisture above 5 per cent creates conditions for mould growth in storage. This is a food safety issue, not just a quality concern. Cacao powder stored in humid warehouse conditions without adequate sealing is at risk.
- Reduced shelf life: High moisture cacao powder has a significantly shorter shelf life than well-dried material. A powder arriving at 5.5 per cent moisture will degrade faster than one arriving at 4.0 per cent, regardless of its origin or processing quality.
- Poor flowability: In automated production systems — dosing equipment, hoppers, conveyor systems — high-moisture cacao powder flows inconsistently. This creates batch variation that appears as a production problem but originates at the ingredient specification level.
What to check on arrival
- Request moisture content on the COA before accepting a delivery — not after opening the bags.
- Inspect packaging for any signs of moisture damage, discolouration, or condensation inside sealed bags.
- Check storage conditions at your facility. Cacao powder should be stored in a cool, dry, sealed environment below 20°C.
- For high-volume operations, consider spot-testing moisture on arrival using a calibrated moisture analyser.
Fermentation Quality — The Upstream Specification That Determines Everything Downstream
Fermentation quality is the one specification that cannot be corrected during processing. Every other parameter on this list — fat content, particle size, pH, and moisture — is a downstream processing decision. Fermentation is an upstream biological process. Once it is done, it is done.
A batch of cacao beans that reached only 70 per cent fermentation will produce cacao powder with a flat, astringent, underdeveloped flavour profile. No roasting adjustment, no alkalisation choice, no milling process will create the flavour complexity that proper fermentation would have produced. The ceiling for that batch's performance was set at the cooperative.
What the fermentation rate tells you
The fermentation rate — expressed as a percentage of fully fermented beans per lot — is determined by a cut test: slicing beans in cross-section and assessing the colour and texture of the interior. A fully fermented bean shows a brown, crinkled interior. An underfermented bean is grey, slate-coloured, or purple — the colour of low tannin conversion and incomplete flavour precursor development.
The premium cacao benchmark is at least 85 per cent fully fermented beans per lot. Standard commercial cacao typically falls between 75 and 85 per cent. Material below 75 per cent fermentation is commodity-grade at best.
Why this matters in production
A fermentation rate below 75 per cent means your cacao powder will taste more bitter and astringent than specified. No amount of recipe adjustment will fully compensate. This cacao is not suitable for premium applications where the flavour is the product.
A fermentation rate of 85 per cent or above from a documented, named cooperative means the full genetic and environmental potential of that origin has been developed. The flavour precursors are present. Processing converts them.
What to require: Ask for fermentation records per lot — not just the fermentation rate on the COA, but the duration, the turning protocol, and the cut test methodology used. A premium cacao supplier with genuine cooperative relationships provides this as standard. A commodity trader cannot.
How to Read a COA as a Production Planning Document
A Certificate of Analysis is typically treated as a compliance document. It arrives with the shipment. Someone files it. Production proceeds. This is the wrong approach.
A COA from an accredited third-party laboratory contains the production performance specification for that specific lot. Reading it correctly — before the bags are opened — allows you to predict how the cacao will behave and adjust production parameters proactively.
The table below maps COA fields to production implications and tells you what to do if a value is outside the range.
| COA Field | Target Range | Production Implication | What to Do If Out of Range |
|---|---|---|---|
| Moisture (%) | < 5.0 | Shelf life and flowability. Above 5% = elevated mould risk. | Reject or quarantine. Do not store above 5%. |
| Fat / Cocoa butter (%) | 10–22% (per spec) | Mouthfeel and viscosity. Must match your product specification. | Reorder at the correct fat spec. Reformulate only if urgent. |
| pH | 5.0–6.0 (natural) / 6.8–8.5 (Dutch) | Flavour, colour, baking chemistry. Must match your application. | Do not substitute natural for Dutch or vice versa without reformulation. |
| Ash (%) | < 9.0 | Mineral content indicator. High ash may indicate poor origin quality. | Flag for supplier query if significantly above range. |
| Microbial: Total count | < 10,000 CFU/g | General hygiene standard. | Reject. Notify the supplier immediately. |
| Microbial: Salmonella | Not detected in 25g | Food safety — zero tolerance. | Reject immediately. Do not use. Regulatory notification may apply. |
| Microbial: E. coli | < 10 CFU/g | Hygiene standard. | Reject. Notify the supplier. |
| Heavy metals: Cadmium (ppm) | < 0.30 (EU standard) | Regulatory limit for EU markets. Critical for export products. | Do not use for EU-bound products. Seek a replacement lot. |
| Fermentation rate (%) | ≥ 85% (premium) / ≥ 75% (commercial) | Flavour quality upstream. Below 75% = astringent profile. | Accept for non-flavour-critical applications only. Adjust expectations. |
Three things to check immediately on every COA
- Check moisture first: If moisture is above 5 per cent, flag immediately before storage. This is a time-sensitive quality issue.
- Check pH against your leavening system: If you're switching from natural to Dutch-processed or vice versa, and your recipe uses baking soda, the leavening must be reconfigured.
- Check cadmium for EU-bound product: If any of your products or your customers' products reach European markets, cadmium must be below 0.30 mg/kg for cacao powder. This is a legal requirement, not a quality preference.
Not all COAs are equal. A COA issued by the supplier themselves, or by the origin country's export authority, is not the same as a COA from an accredited independent laboratory. Self-issued COAs may reflect testing that was not conducted by an independent party using validated methods. Export authority COAs typically cover only the specifications required for export certification — not the full production specification set.
For cacao used in food manufacturing — particularly for organic claims, EU export, or retail channels with supplier audit requirements — COAs from accredited independent laboratories (NATA-accredited in Australia, ISO 17025-accredited internationally) are the defensible standard. Request these specifically, and confirm that the lab name and accreditation number are present on the document.
Specifying Cacao for Production: What to Include in Every Supplier Brief
A complete cacao specification brief for a food manufacturing application should include the following.
Specification Parameters
- Origin and variety — country, region, cooperative, and variety. This sets the flavour ceiling.
- Fat content — state the range: '10–12 per cent' for standard, '20–22 per cent' for high-fat. Required for any application where mouthfeel or viscosity is critical.
- Particle size — specify d90 or d50 measurement if your application is beverage or texture-sensitive. The default assumption is 20–30 microns if unspecified.
- pH / processing method — natural or Dutch-processed. If natural, confirm pH range. Essential for any baking application or health claim.
- Moisture — require below 5 per cent. State 4.5 per cent as a premium target.
- Fermentation rate — require 85 per cent or above for premium applications. Accept 75 per cent minimum for standard commercial use.
- Certification requirements — food safety certification (BRC, FSSC 22000, ISO 22000) at the processing facility. Organic certification chain if relevant.
- COA requirement — specify that the COA must come from an accredited third-party laboratory, not self-issued, and must cover moisture, fat, pH, microbial counts, and heavy metals.
This brief takes ten minutes to write. It eliminates the most common sources of production inconsistency before they occur. Working through the cacao powder specifications with your supplier before the first order is the most productive conversation you can have.
Specifications Are What You Are Actually Buying
Origin tells a story. Specifications determine performance. A premium single-origin cacao with undefined fat content, unknown particle size, and an unverified fermentation rate is an incomplete purchase decision. The same origin, correctly specified and properly documented, is the foundation of a consistent, high-performance product.
The questions to ask of any cacao supplier are simple: what are the specification ranges for this product, what does the COA from an accredited laboratory show, and can you meet this brief consistently across seasons? A supplier who can answer those questions clearly, with paperwork, is the supplier worth buying from.
