Screen size, moisture, defects, process and sample data answer different questions. They should not be compressed into a single grade label or a claim about cup quality. This guide gives a practical way to compare Robusta specifications without inventing thresholds that were not agreed for the purchase.<\/p>\n<h2 id=\"sec-1\">Begin with the roasting job<\/h2>\n<p>Write what the coffee must do in the finished product. A component used in a blend may be assessed for consistency, body and interaction with the other coffees. A single-origin programme may require closer attention to identity and sensory expression. A soluble or industrial application may prioritise different technical and supply criteria. These are buyer goals, not promises from a supplier.<\/p>\n<p>Ask the roasting or quality team to name the fields that can influence the decision. Then separate required fields from useful context. A document with ten numbers is not stronger than one with five relevant, well-defined fields. Record the product form, sample purpose, crop or production period where supplied and the lot or reference code.<\/p>\n<h2 id=\"sec-2\">Understand what a screen designation does<\/h2>\n<p>Screen designations describe a size classification within the system used for the coffee. A label such as S13, S16 or S18 should be read with the size distribution, method and tolerance. The designation does not by itself prove a sensory profile, defect result or roast performance. Ask what percentage falls into each screen range and whether the table states a permitted variation.<\/p>\n<p>The <a href=\"https:\/\/varieties.worldcoffeeresearch.org\/robusta\" target=\"_blank\" rel=\"noopener\">World Coffee Research Robusta catalogue<\/a> helps explain the species and variety context. It does not define a commercial screen grade for an individual export lot. Keep agronomic background and contract specification as separate layers. If a supplier uses a local or commercial grade name, retain that wording and ask for the definition used in the offer.<\/p>\n<p>When comparing offers, align units and sampling. Two tables may show the same screen name but refer to different distributions or samples. A useful comparison has a row for method, date, lot and tolerance, even when the answer is \u201cnot supplied\u201d. That missing information is a decision point rather than a reason to insert a default value.<\/p>\n<h2 id=\"sec-3\">Read moisture with time and storage<\/h2>\n<p>Moisture is a measurement at a time and under conditions. Record the date, sample location, method or device when available, packaging and storage context. Coffee can be exposed to different environments after the test, during transport or after opening a bag. A later recheck is not automatically evidence that the first measurement was wrong.<\/p>\n<p>Ask how the reported number was obtained and whether the test is intended for screening, release or another purpose. If the specification states a range, clarify whether the range is a target, a contractual limit or an observation. Do not transform a range into a guaranteed property of every future lot.<\/p>\n<p>Moisture should be considered with process, storage and the physical sample. It does not replace a sensory assessment, and it should not be used alone to predict a roast outcome. When the buyer\u2019s protocol requires a recheck, write the trigger and responsible reviewer into the approval note.<\/p>\n<h2 id=\"sec-4\">Define defects before counting them<\/h2>\n<p>Defect language must have a shared definition. Ask whether the result is a count, a percentage, a class or another measure, and identify the sample size. A small inspection sample can reveal issues worth investigating but should not automatically represent a complete shipment. The buyer should know whether the result is a lot estimate, a release check or a preliminary observation.<\/p>\n<p>Record primary and secondary categories only when the applicable method defines them. Avoid importing thresholds from another contract or origin without agreement. If the supplier uses a house format, request the definitions or a cross-reference to the standard used. A clear method is more useful than a familiar-looking number whose meaning is unknown.<\/p>\n<p>Keep physical inspection and sensory testing connected but distinct. A defect count can guide a decision to investigate; cupping or roast evaluation can reveal a different risk. Neither should be written as a universal quality score without stating the method, sample and scope.<\/p>\n<h2 id=\"sec-5\">Include process and crop information<\/h2>\n<p>Process descriptions should identify the stage relevant to the product: natural, washed, honey or another method if that is the wording supplied for the lot. A process name alone does not establish drying conditions, storage history or sensory result. Ask which part is documented and which part remains a supplier description.<\/p>\n<p>Crop or production period is another anchor. It helps the buyer organise samples and understand whether a specification is current, but it does not prove that all lots from a period are identical. Use dates or supplied period wording and preserve the source. If the document is undated, ask for the review date before treating it as current.<\/p>\n<h2 id=\"sec-6\">Build a specification table that can be audited<\/h2>\n<div class=\"vh-cc-table\">\n<table>\n<thead>\n<tr>\n<th>Field<\/th>\n<th>What to record<\/th>\n<th>What it does not prove<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Screen<\/td>\n<td>Designation, distribution, method and tolerance<\/td>\n<td>Complete sensory quality<\/td>\n<\/tr>\n<tr>\n<td>Moisture<\/td>\n<td>Value, date, method and storage context<\/td>\n<td>Permanent condition after transport<\/td>\n<\/tr>\n<tr>\n<td>Defects<\/td>\n<td>Definition, sample size and result<\/td>\n<td>Every defect in an untested lot<\/td>\n<\/tr>\n<tr>\n<td>Process<\/td>\n<td>Supplied process description and evidence scope<\/td>\n<td>A guaranteed cup profile<\/td>\n<\/tr>\n<tr>\n<td>Sample<\/td>\n<td>Code, date, purpose and lot connection<\/td>\n<td>Approval of a different shipment<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<p>Version the table. If the supplier sends an update, retain the prior version and note what changed. The buyer can then ask whether the product changed, the measurement changed or only the document changed. This is especially useful when multiple teams are reviewing the same opportunity.<\/p>\n<h2 id=\"sec-7\">Connect specifications to a sample and roast trial<\/h2>\n<p>Before a roast trial, photograph or record the sample label, quantity and condition. Agree the roast protocol, sample preparation, rest time and evaluation fields. Use the same protocol when comparing options, while allowing the roasting team to adjust later for production. The purpose is to observe suitability under a known method, not to create a universal score.<\/p>\n<p>Compare the trial with the specification without forcing a match. An unexpected result may lead to a question about sample representativeness, storage, process, measurement or roast settings. Note the question and choose the next test. If the lot changes, the approval note should state whether a new sample is needed.<\/p>\n<p>The <a href=\"https:\/\/vinhhiepgl.com\/en\/gia-lai-coffee-export-sample-approval-traceability\/\">sample approval guide<\/a> shows how to retain the decision with the lot identity. The <a href=\"https:\/\/vinhhiepgl.com\/en\/coffee-knowledge\/\">coffee knowledge hub<\/a> provides further reading on green coffee concepts. Use those pages as background; product-specific confirmation still comes from the current supplier file.<\/p>\n<h2 id=\"sec-8\">Compare two offers without a false ranking<\/h2>\n<p>Suppose Offer A shows S16 and a moisture value, while Offer B shows S16 and a defect class. They are not yet directly comparable. Ask both parties for the missing fields, methods, dates and sample links. If one party cannot supply a field, mark the comparison as incomplete rather than assuming the missing value is acceptable.<\/p>\n<p>If both tables are complete, compare the fields in the order the buyer\u2019s use requires. A roasting team may review sample behaviour first, then technical consistency and storage plan. Purchasing can add commercial terms after the technical gate. This staged order keeps a price or a single grade label from dominating the whole decision.<\/p>\n<h2 id=\"sec-9\">Worked example: screen size is not the decision<\/h2>\n<p>This hypothetical case begins with two samples labelled for the same screen. The buyer uses the same roast profile and records different moisture readings, defect observations and sensory results. Instead of declaring one origin better, the team checks whether the samples represent equivalent lots and whether the readings used the same method. One sample is linked to a current lot; the other is a preliminary type reference.<\/p>\n<p>The team accepts the first sample for a next-stage request and asks for a new, labelled sample from the second proposed lot. The conclusion is about evidence and suitability for that test, not a permanent ranking of Gia Lai coffee. The example shows why the specification, sample and decision record should travel together.<\/p>\n<h2 id=\"sec-10\">Questions for the supplier<\/h2>\n<p>Ask: What does each field mean? Which method and unit apply? What is the sample size? Which date and lot does the result cover? What tolerance is accepted? What change triggers a recheck? Who confirms the final lot? These questions can be placed beside the table so the supplier can respond line by line.<\/p>\n<p>Avoid importing quality thresholds from a different buyer. Thresholds can depend on contract, use, method and destination. If your team has a required limit, state that it is your requirement and ask whether the proposed lot can be assessed against it. Do not attribute the limit to a public source unless that source actually states it.<\/p>\n<h2 id=\"sec-11\">Brief Vinh Hiep for a useful specification response<\/h2>\n<p>Send the product form, intended roast use, destination, expected volume, fields to compare, sample protocol and document questions. Link the request to the <a href=\"https:\/\/vinhhiepgl.com\/en\/gia-lai-coffee-origin-guide\/\">Gia Lai origin guide<\/a>, the <a href=\"https:\/\/vinhhiepgl.com\/en\/gia-lai-coffee-export-what-buyers-verify\/\">buyer verification guide<\/a> and the <a href=\"https:\/\/vinhhiepgl.com\/en\/gia-lai-coffee-export-documentation-guide\/\">documentation guide<\/a>. Ask which specification version applies to the proposed coffee and how the sample relates to it.<\/p>\n<h2 id=\"sec-12\">Read a specification line by line<\/h2>\n<p>Begin with the product identifier, because every later field depends on knowing which coffee the table describes. Next read the process wording and the crop or production period supplied. Then examine the measurement fields. For screen data, record whether the table gives a distribution or only a named class. For moisture, record the measurement date and method. For defects, record the definition, sample size and calculation. Finally, read the notes and tolerances; a footnote can change how a number should be interpreted.<\/p>\n<p>Use a comparison sheet that preserves the original unit and a normalised field only when the conversion is verified. Do not round a value until the team agrees how rounding affects the acceptance rule. If a field is missing, write \u201cnot supplied\u201d and add a question. A blank cell is visible; an invented value is not. When the supplier sends an explanation, keep the explanation beside the field rather than hiding it in a general email.<\/p>\n<p>The quality team can also record what it will recheck on arrival. That may include a visual check, moisture measurement, sample retention or a roast trial. The recheck plan should refer to the accepted specification and identify who decides if results differ. It should not be written as a guarantee that a future shipment will match a preliminary sample; it is a control that makes a difference visible early.<\/p>\n<h2 id=\"sec-13\">Use specifications to ask better questions<\/h2>\n<p>A specification table is also a conversation tool. Mark a field as confirmed, unclear, out of scope or required by the buyer. Send the table with the questions in the same order as the supplier\u2019s document. That format reduces translation between teams and makes it easier to identify whether a disagreement concerns a number, a definition or the sample itself. The buyer can then decide whether to request clarification, a new test or a different sample.<\/p>\n<p>When a specification is translated, keep the original term beside the translation. Technical words can carry a narrower meaning in a contract or laboratory report. Preserving the source wording helps reviewers check that the interpretation has not changed. It also gives the supplier a precise phrase to respond to if the translated field is unclear.<\/p>\n<h2 id=\"sec-14\">Frequently asked questions<\/h2>\n<h3>Which Robusta fields deserve priority?<\/h3>\n<p>Prioritise the fields that affect the buyer\u2019s intended use and can be checked consistently: product form, sample identity, process description, moisture, screen distribution, defined defects and the relevant sensory or roast protocol. The order depends on the application. A field is valuable when its method and scope are clear, not simply because it appears on a familiar template.<\/p>\n<h3>Does S16 mean the coffee will roast well?<\/h3>\n<p>No. A screen designation describes a size category within a classification system. Roast behaviour also depends on factors such as physical condition, process, storage, sample identity and the roast method. Use the designation as one comparison field, then verify the sample under a controlled trial.<\/p>\n<h3>When should moisture be checked again?<\/h3>\n<p>Recheck when the buyer\u2019s protocol requires it, when storage or packaging changes, when the sample has travelled or when the proposed lot differs from the tested reference. Record why the new measurement was taken and keep both results. A recheck should clarify the current condition rather than overwrite the history.<\/p>\n<h3>Can a specification replace a sample?<\/h3>\n<p>A specification can support screening and comparison, but it cannot show how the particular coffee behaves under the buyer\u2019s process. A sample is especially important when the product, process, lot or intended use is new. Keep the specification and sample connected; neither should be presented as proof of the other.<\/p>\n<p>Continue through the <a href=\"https:\/\/vinhhiepgl.com\/en\/gia-lai-coffee-export\/\">Gia Lai coffee export hub<\/a> and <a href=\"https:\/\/vinhhiepgl.com\/en\/gia-lai-coffee-origin-guide\/\">Gia Lai coffee origin guide<\/a>.
