Not every coffee sample carries the same weight. Before you cup, confirm what kind of sample is on the table and what decision it is supposed to support.

An offer sample helps you decide whether a coffee is worth pursuing. It may show the general cup profile of a lot, but it is not always the final shipping reference. Treat it as a sourcing signal, not automatic proof that the exact coffee will arrive unchanged.

A type sample shows a supplier’s general quality, style, or expected profile. It is useful for early sourcing conversations, especially when you are learning what a producer, cooperative, exporter, or importer can provide. It should not be treated as proof of a specific contracted lot.

A representative sample is pulled from all bags, or from a defined percentage of bags, to represent a lot. This matters because approval is only as strong as the sample’s relationship to the coffee being sold. If the sample is not representative, the approval is not very useful.

A pre-shipment sample, often called a PSS, is taken before export or loading. It confirms whether the coffee about to ship still meets the agreed expectations. For many contracts, this is the key quality gate before the shipment moves.

An SAS, or subject to approval sample, means the sale or next action depends on buyer acceptance. Contracts may specify whether approval is based on a pre-shipment sample, an arrival sample, or another agreed sample stage.

An arrival sample is pulled after the coffee lands and enters the warehouse. It helps confirm that the coffee survived transport and still matches the approved reference closely enough to release, roast, blend, or sell.

Here is the practical decision logic:

The approval process starts before the courier arrives. A vague request often produces a vague sample, and vague samples lead to weak decisions.

Tell the supplier or importer what the coffee needs to do. Is it for a single-origin filter menu, an espresso blend, a private label project, a trial order, or a replacement for an existing production coffee? The answer changes what “good” means. A lively washed coffee for a rotating pour-over slot is not being judged against the same expectations as a steady chocolate-driven espresso component.

Your request should identify the lot and the sample type, then connect that sample to the commercial decision you need to make. Ask for origin, farm, cooperative, exporter, or mill information; harvest or crop year; process method; variety, screen size, and grade if relevant; available volume and bag count; expected shipment timing; moisture and water activity if available; packing details and warehouse location if the coffee has already landed; and the proposed approval term, such as SAS, SAPS, or arrival approval. When the order requires documentation, request the relevant spec sheet, certificate of analysis, organic or Fair Trade certificates, and packing list details at the same time.

Also state your target profile. “Clean washed coffee for a medium roast espresso component with chocolate sweetness and no ferment notes” is much more useful than “send something nice.”

Just as important, say what is unacceptable. If your program cannot use phenolic notes, moldy cups, heavy ferment, visible insect damage, high moisture risk, or sharply herbal under-ripe character, put that in the request. Clear limits save everyone time.

When the sample arrives, treat it like a quality record. Log the date received, supplier, lot code, sample type, green weight, packaging condition, and any visible damage. If the bag is torn, wet, unlabeled, or contaminated by odor, record that before roasting.

A sample roast should reveal the coffee, not the equipment or the operator’s mood that day. Keep your sample roast protocol consistent enough that two coffees can be compared fairly. Track batch size, charge temperature, roast time, development time, color if measured, and rest time before cupping. These details may feel minor until a decision is questioned; then they become the difference between a defensible approval and a vague memory.

Use duplicate cups when possible. For higher-value lots, use several cups. One bowl can hide a defect or exaggerate a small issue. Multiple cups make uniformity and clean cup easier to judge.

During cupping, record aroma, flavor, acidity, body, sweetness, balance, aftertaste, uniformity, clean cup, and defects. Scores can be useful, but the notes matter more than the number when a decision is challenged later. “84.5” alone does not explain much. “Clean cup, medium body, caramel sweetness, orange acidity, slight drying finish, no defect across five cups” gives the team something it can act on.

Physical checks should sit beside sensory notes. Depending on the value and risk of the order, inspect for visible defects, foreign matter, insect damage, mold, discoloration, moisture concerns, water activity concerns, and bag or marking consistency. A clean cup is important, but green coffee is still a physical product moving through bags, warehouses, containers, and ports.

Approval should not depend on one person saying, “I liked it.” Use a decision framework.

Approve the sample when it matches the contracted or requested profile, is free from serious sensory defects, meets physical requirements, and fits the intended product. A coffee for a bright seasonal filter slot does not need the same body as an espresso base. Approval should be tied to use.

Reject when defects or mismatches are clear. Common rejection triggers include mold, phenolic character, chemical contamination, severe ferment, sour rot, baggy or papery age, foreign odor, unacceptable moisture or water activity, major visible defects, or a profile that cannot serve the agreed product.

Re-cup when the result is unclear. Maybe the roast was uneven. Maybe one cup showed a defect but the others were clean. Maybe the panel disagreed. A re-cup is not indecision; it is a way to avoid approving or rejecting based on bad data.

Conditional approval can be useful, but only when the condition is specific and practical. A buyer might approve subject to fresh PSS confirmation before shipment, approve only if the coffee is packed with the agreed liner or protective material, approve for a trial order rather than full container volume, approve pending arrival sample review before release, or approve the coffee for a revised use, such as a blend component rather than a single-origin release.

Normal agricultural variation should not be confused with failure. Coffee can shift slightly between offer, PSS, and arrival. Descriptors may move from peach to citrus, or the aroma may soften during transit. That is different from mold, severe fade, phenolic character, or a cup that no longer resembles the approved quality.

Once the decision is made, write it down in a way that operations can use. Good approval communication is short, specific, and tied to the next action.

An approval message should include the sample type, lot ID or contract reference, cup date, evaluator or panel, score or internal pass/fail result if used, key tasting notes, approval status, and requested next step. For a PSS approval, also ask for confirmation of shipping instructions, container booking timeline, packaging or liner requirements, documents needed, and expected ETD and ETA.

A simple approval message can look like this:

> We approve the PSS for Lot [ID], cupped on [date] by [team/person]. The sample showed [notes], with no serious sensory defects detected across [number] cups. Please proceed with the next shipment step and confirm booking timeline, packing details, shipping documents, ETD, and ETA.

A rejection should be just as clear, but not emotional:

> We cannot approve Sample [ID] cupped on [date]. Across [number] cups, we found [specific issue], including [sensory or physical evidence]. Please advise whether a replacement sample, revised lot, re-cup, discount discussion, or no-sale outcome is appropriate under the agreed terms.

Conditional approval needs extra care:

> We approve Sample [ID] conditionally for [use/order], provided that [specific condition] is confirmed before [shipment/release]. If the condition cannot be met, please pause the next step and send an updated sample or proposal.

Share useful feedback when possible. Producers and exporters benefit from knowing more than yes or no. Clear notes help future offers become more relevant, and they keep the commercial relationship grounded in evidence instead of preference alone.

PSS approval often triggers action, but it does not mean the coffee is ready for use.

The approval may be shared with the supplier, exporter, and producer. Shipping instructions may follow. Then the exporter needs a container booking, which depends on shipping line space, port conditions, route availability, documentation, and local timing. No single party controls every step.

From there, the coffee may pass through export processing, loading, ocean transit, port arrival, customs clearance, agency checks, drayage, and warehouse unloading. For U.S. imports, FDA, CBP, or other agency activity can affect timing if paperwork is inconsistent or a shipment is held for inspection.

At warehouse receiving, someone should confirm bag count, lot markings or ICO marks, seal numbers, visible damage, water marks, torn bags, spillage, and storage location. These receiving records matter if the arrival sample later raises questions. They also help separate cup quality issues from transit, handling, or documentation issues.

Build lead time into production planning. Approved coffee can still take weeks to become available, especially if the origin is far away, container space is tight, port activity is slow, or documentation needs correction. A disciplined coffee sample approval process should therefore connect QC decisions to operations, not stop at the cupping table.

When the arrival sample arrives, cup it using the same or comparable protocol used for PSS approval. Compare it against the approved sample notes, score range, defect status, physical data, and intended use.

Acceptable variance may include slight changes in flavor descriptors, lower aromatic intensity, or a softer cup if the coffee is still clean and suitable. Serious variance includes mold, baggy age, sourness, phenolic notes, chemical taint, severe fade, foreign contamination, or a profile that no longer fits the approved product.

Document everything: dates, photos, roast logs, cupping forms, moisture or water activity readings if available, and panel comments. If the coffee fails, pause release if possible and notify the importer or supplier quickly.

Possible outcomes include re-cup, replacement, claim, discount, no sale, release for a different use, or escalation under contract terms. The stronger your approval record, the easier that conversation becomes.

The most common mistakes happen before anyone tastes the coffee.

One is approving an offer sample as if it were a representative PSS. Another is failing to define the approval term in the contract before the sample arrives. If the team does not know whether approval is based on PSS, arrival, or both, the decision can get messy fast.

During evaluation, inconsistency causes problems. Different roast levels, undocumented cupping methods, single-cup decisions, and one-person approvals are risky for high-value or production-critical lots. Even strong cuppers make better decisions when the process reduces noise around the cup.

After approval, teams often go quiet. They do not send specific feedback, do not confirm shipping details, and do not compare arrival samples against the approved reference. That leaves too much room for memory, assumption, and avoidable disagreement.

A short internal checklist can prevent most of this. Confirm the sample type, whether it is representative of the lot, what product use it is being approved for, whether roast and cupping conditions were controlled, whether sensory and physical checks were documented, what contract term applies, what exact decision was communicated, and what happens next if the arrival sample differs.

How long should the coffee sample approval process take?

For an offer sample, many teams can log, roast, cup, and respond within a few business days. PSS and arrival samples should be handled faster because shipment or release may be waiting on the decision. The exact timing depends on your QC schedule, panel availability, and whether a re-cup is needed.

Can one person approve a coffee sample?

For low-risk samples, one trained evaluator may be enough. For expensive lots, new suppliers, production-critical coffees, or disputed results, use at least two evaluators or a small panel. It gives the decision more balance and makes the record stronger.

Is a different flavor note between PSS and arrival always a problem?

No. Coffee is an agricultural product, and descriptors can shift. A cup moving from “stone fruit” to “citrus” may still be acceptable if the quality, cleanliness, sweetness, and intended use remain intact. Defects, contamination, severe fade, or major profile mismatch are different.

Should buyers approve with conditions?

Yes, but only when the condition is specific. “Approved if quality is good” is too vague. “Approved subject to arrival sample review before release” or “approved if packed in the agreed liner” is clear enough to manage.

The best coffee sample approval process is repeatable. It defines the sample type, improves the request, controls the roast and cupping method, sets approval criteria, documents the decision, communicates next steps, tracks logistics, and compares the arrival sample before release.

Turn the workflow into a simple internal SOP before approving a trial order. It does not need to be complicated. It just needs to be clear enough that your buyer, QC lead, importer, and operations team all make the same decision from the same evidence. MR.VIET can support that kind of sourcing conversation best when sample approval is treated as a shared quality record, not a quick tasting note.
