Product Specifications

By Viet Coffee Source

Product specifications define the technical, commercial, sensory, packaging and documentation requirements that a coffee product must meet before approval, production and shipment. A clear specification helps the buyer, supplier, processor, roaster, manufacturer, laboratory and inspection company evaluate the same product against the same criteria. Without a written specification, descriptions such as “premium coffee,” “export quality,” “medium roast” or “good cup” can be interpreted differently by each party.

Viet Coffee Source helps professional buyers develop, review and coordinate product specifications with selected coffee producers, processors, exporters, roasters, instant-coffee manufacturers, packaging suppliers, laboratories and inspection partners in Vietnam. Support may include specification templates, sample coordination, physical and sensory criteria, formulation review, packaging requirements, labeling data, laboratory-test planning, acceptance tolerances, document requirements and pre-shipment verification. Final specifications depend on the exact product, supplier, intended use, destination market, production process and contract.

Why Product Specifications Matter

A product specification converts commercial expectations into measurable requirements. It provides a technical reference for quotations, samples, contracts, quality control, production, packaging, inspection, claims and repeat orders.

A structured specification can help:

Reduce misunderstandings between buyer and supplier
Support accurate quotations
Define measurable quality requirements
Create a basis for sample approval
Improve consistency between lots
Support laboratory and inspection planning
Clarify packaging and labeling requirements
Reduce production errors
Support acceptance and rejection decisions
Provide evidence during claims or disputes
Improve repeat-order consistency
Connect quality requirements with export documentation

The specification should be agreed before commercial production begins. It should not be created only after a quality problem occurs.

Specification, Sample and Contract

A written specification, an approved sample and a commercial contract serve different but complementary purposes.

Reference	Main Purpose	Typical Content
Product specification	Defines measurable technical and quality requirements	Origin, grade, moisture, defects, sensory profile, formula, packaging and tolerances
Approved sample	Provides a practical physical and sensory reference	Appearance, cup profile, roast, grind, aroma, packaging and product presentation
Commercial contract	Defines legal and commercial obligations	Quantity, price, payment, Incoterm, delivery, claims, inspection and remedies

A sample should not replace a written specification, and a specification should not replace the commercial contract. The three references should be consistent.

Specification by Coffee Product Type

Different coffee formats require different technical criteria. The same template should not be applied without adjustment to every product.

Product Type	Common Specification Areas	Primary Commercial Use
Green coffee	Origin, species, process, screen, moisture, defects, density, cup profile and bag format	Roasting, blending and industrial processing
Roasted whole bean	Bean blend, roast level, roast color, sensory profile, degassing, packaging and shelf life	Retail, food service and private label
Ground coffee	Roast, grind distribution, sensory profile, oxygen protection, fill weight and packaging	Filter, espresso, traditional brewing and retail
Drip coffee	Coffee dose, grind size, filter material, extraction performance, sachet seal and box count	Single-serve retail and hospitality
Instant coffee	Process type, moisture, bulk density, solubility, color, flavor, particle size and packing format	Beverage production, food service and retail
Three-in-one products	Formula, coffee content, sugar, creamer, additives, allergens, sensory profile and sachet weight	Retail and food-service beverage preparation
Private-label products	Product quality, formula, artwork, labeling, barcode, coding, cartons and shipping marks	Branded retail programs

The specification should be designed around the intended application. Coffee for espresso, soluble manufacturing, milk beverages, traditional phin brewing or retail filter use may require different performance criteria.

Product Identification

Every specification should begin with clear product identification so that it cannot be confused with another item.

Identification may include:

Product name
Internal SKU
Buyer product code
Supplier product code
Product category
Brand name
Private-label status
Country of origin
Manufacturing location
Specification version
Effective date
Authorized approvers

Specification versions should be controlled. Production should use the current approved version rather than an outdated document.

Intended Use

The intended use helps the supplier understand how the coffee will be roasted, brewed, processed, blended or sold. This can influence the most appropriate quality criteria.

Intended uses may include:

Espresso roasting
Filter-coffee roasting
Traditional Vietnamese phin preparation
Cold brew
Milk-based beverages
Industrial extraction
Instant-coffee formulation
Three-in-one production
Retail whole bean
Retail ground coffee
Food-service supply
Private-label distribution

A coffee that performs well for one application may not be suitable for another, even if the general quality appears acceptable.

Origin Requirements

Origin requirements may be broad or highly specific depending on the program. Buyers should distinguish between country of origin, region, province, farm group, cooperative, estate and individual farm.

Origin criteria may include:

Country
Province or region
District
Farm or producer group
Altitude range
Growing environment
Crop year
Harvest period
Traceability level
Required origin documents

Origin claims should be supported by available supplier, lot and traceability records. Broader commercial lots may not provide the same traceability detail as selected specialty lots.

Coffee Species and Variety

The specification should identify whether the product is Robusta, Arabica, Excelsa, a blend or another agreed coffee type. Variety information may be required where it is commercially relevant and verifiable.

Species and variety requirements may include:

Coffea canephora
Coffea arabica
Coffea liberica or Excelsa
Specified variety or cultivar
Permitted varietal mix
Minimum percentage of one species
Blend composition
Verification method

Species claims should not be based only on appearance when reliable production records are required.

Crop and Production Period

Crop year or production period can affect freshness, availability, price and cup consistency. The terminology should be clear because crop references may differ between producing and buying markets.

The specification may define:

Current crop
Specific crop year
Maximum age from harvest
Maximum age from roasting
Production month
Packing month
Minimum remaining shelf life at shipment

When older crop coffee is permitted, storage condition and quality criteria should still be defined.

Processing Method

The processing method influences physical appearance, cup character, moisture behavior and defect risk. It should be identified when relevant to the product.

Methods may include:

Natural or dry process
Washed process
Honey process
Wet-hulled process
Polished coffee
Steam-treated coffee
Decaffeinated coffee
Fermentation-controlled lots
Other buyer-approved methods

If fermentation parameters or special processes are part of the commercial claim, the required records and acceptance criteria should be stated.

Green-Coffee Grade

Commercial grade descriptions should be supported by measurable criteria. Grade terminology can vary between suppliers, origins and markets.

A green-coffee grade may refer to:

Screen size
Defect count
Moisture
Foreign matter
Bean color
Processing method
Origin
Cup requirements
Sorting level
Commercial classification

The buyer should not rely on the grade name alone. The specification should state the underlying limits.

Screen-Size Specification

Screen size is commonly used for green-coffee classification and can affect roast uniformity and appearance.

A screen specification may include:

Main screen size
Percentage retained above the required screen
Percentage permitted below the required screen
Percentage permitted above the required screen
Sample weight
Sieve method
Allowed tolerance

A statement such as “Screen 18” should clarify whether it means a minimum retained percentage, a screen range or another commercial interpretation.

Moisture Specification

Moisture is an important requirement for green coffee, instant coffee and some formulated products. The specification should identify the target range, test method and tolerance.

Moisture requirements may include:

Minimum value
Maximum value
Target range
Test method
Instrument type
Number of readings
Sampling procedure
Retest procedure

Different moisture meters and laboratory methods may produce different results. Buyer and supplier should use the same agreed basis for acceptance.

Water-Activity Specification

Water activity may be relevant to product stability, microbiological control, caking and shelf life. It is different from total moisture and should be specified separately when required.

The specification may identify:

Maximum water activity
Test temperature
Conditioning time
Instrument requirement
Sampling frequency
Corrective action

Water-activity limits should be established with suitable technical or regulatory support for the exact product.

Defect Limits

Defect limits should identify the grading system, sample size and maximum permitted defects. Different standards may count equivalent defects differently.

Possible defect categories include:

Full black beans
Partial black beans
Full sour beans
Partial sour beans
Dried cherries
Fungus-damaged beans
Insect-damaged beans
Broken beans
Immature beans
Shells
Husks
Foreign matter

The specification should clarify whether the requirement applies to individual defect counts, total equivalent defects or both.

Foreign-Matter Limits

Foreign matter can create food-safety, processing and equipment risks. The specification should identify prohibited materials and any measurable tolerance.

Foreign matter may include:

Stones
Metal
Glass
Wood
Plastic
Soil
String
Bag fibers
Non-coffee plant material
Other contaminants

Certain materials may require zero tolerance because of safety risk. The control method may include magnets, metal detection, destoning, optical sorting, sieving or manual inspection.

Bean Appearance and Color

Appearance requirements may help define processing consistency, freshness and commercial presentation.

Visual criteria may include:

Uniform bean color
Absence of abnormal discoloration
Limited broken beans
Limited insect damage
Absence of visible mold
Consistent processing appearance
Absence of excessive husk
Representative photographic standard

Visual approval should be supported by measurable physical and sensory criteria rather than used alone.

Density Specification

Density may be relevant for roasting behavior, green-coffee consistency and instant-coffee performance. The method should be defined because results depend on sample preparation and measurement conditions.

A density specification may include:

Bulk density range
Apparent density
Measurement vessel
Sample preparation
Compacted or uncompacted method
Temperature condition
Allowed tolerance

Density should not be treated as a universal quality grade unless its commercial relevance is clearly established.

Sensory Profile

The sensory specification defines the required flavor direction and unacceptable characteristics. It may be descriptive, score-based or based on comparison with an approved reference.

Sensory requirements may include:

Aroma
Flavor
Aftertaste
Acidity
Body
Sweetness
Bitterness
Balance
Clean cup
Uniformity
Defect or taint limits
Overall commercial suitability

The evaluation protocol should identify roast preparation, grind size, dose, water, temperature, brewing or cupping method and acceptance authority.

Cupping Score Requirements

Where a score is required, the specification should identify the evaluation protocol, scoring system, minimum score and treatment of defects.

The specification may state:

Scoring method
Minimum total score
Maximum defect cups
Uniformity requirement
Clean-cup requirement
Evaluator qualification
Number of cups
Dispute-cupping process

A specialty score is not necessary for every commercial program. The acceptance method should match the product’s intended market and use.

Commercial Cup Profile

Commercial coffee specifications may focus on repeatable performance rather than a specialty score. The buyer may define a target suitable for espresso, soluble extraction, milk beverages or traditional brewing.

A commercial profile may include:

Strong body
Low, medium or high acidity
Defined bitterness range
Chocolate, nut, spice or fruit direction
Absence of fermented, moldy, chemical or earthy taints
Blend compatibility
Performance under dark or medium roasting
Comparison with an approved benchmark

Subjective descriptions should be supported by a reference sample whenever possible.

Blend Composition

For green, roasted or ground blends, the specification should identify the approved components and permitted tolerances.

Blend information may include:

Species percentages
Origin percentages
Grade percentages
Roast-component percentages
Permitted substitutions
Tolerance by component
Required lot records
Approval for formula changes

No material substitution should be made without written buyer approval. Buyers developing differentiated products can review our custom blends service.

Common Specification Mistakes

Several mistakes can make a product specification difficult to use or enforce.

Using vague terms without measurable limits
Copying one specification for every coffee product
Failing to identify the test method
Using a grade name without underlying criteria
Approving a sample without recording its identity
Failing to define tolerances
Not stating the sampling method
Not defining the consequence of failure
Ignoring packaging and labeling requirements
Using an outdated artwork version
Adding laboratory requirements after production
Assuming a certificate replaces inspection
Failing to connect the specification to the purchase order
Changing the formula without revision control

A practical specification should be detailed enough for objective evaluation but organized clearly enough for production and inspection teams to use.

Recommended Specification-Development Process

A professional product-specification process may follow these steps:

The buyer defines the product, intended use and destination market.
The buyer identifies mandatory commercial, technical and regulatory requirements.
The supplier confirms available products, processes and testing capability.
A draft specification is prepared.
Representative samples are produced or sourced.
Physical, sensory, packaging and laboratory evaluations are completed as required.
The buyer and supplier compare results with the draft requirements.
Realistic tolerances and test methods are agreed.
The approved sample is identified and retained.
Packaging, artwork, labeling and coding requirements are approved.
Inspection, certificate and document requirements are confirmed.
The final specification is assigned a revision number and approved.
The purchase order references the approved specification.
Commercial production is completed under the approved requirements.
Pre-shipment results are compared with the specification and reference sample.

The exact process may be adapted according to product complexity, order size, supplier capability, buyer risk and destination-market requirements.
