Approving a coffee sample is not the same as saying, “This tastes good.” In wholesale green coffee buying, approval is a quality-control decision with commercial consequences. It can trigger a purchase commitment, release a shipment, confirm that a lot matches contract terms, or begin a rejection and replacement process.
That is why a sound coffee sample approval process needs more discipline than a casual cupping table. You are deciding whether the coffee fits the contract, the roast plan, the customer promise, the price, and the delivery timeline.
A bright, expressive cup may still be wrong for a blend base. A clean but restrained coffee may be exactly right for a price-sensitive wholesale account. A pre-shipment sample may taste close enough to approve, while an arrival sample may reveal transit damage that needs follow-up.
The point is not to make sample approval complicated. The point is to make the decision clear, traceable, and fair to everyone involved.
A sample can be enjoyable and still fail approval. The better question is not simply “Do we like it?” It is, “Does this lot do the job we are buying it to do?”
That job changes with the product. A single-origin filter feature may need clarity, distinct character, and a profile that supports the story you plan to tell customers. An espresso component may need body, sweetness, and reliable performance with milk. A wholesale blend base may need consistency, clean flavor, and cost control more than dramatic tasting notes.
Formal approval should confirm that the sample matches the expected quality and contract description, fits the intended roast and product use, shows no obvious physical warning signs, and has not drifted beyond acceptable variation from earlier samples. It should also make clear what commercial step approval will trigger.
This is where many buyers get into trouble. They cup first, then decide what they were looking for. That gives too much influence to mood, table order, novelty, or one standout cup. Set the target before the sample hits the grinder.
Not every sample answers the same question. Before judging quality, confirm what kind of sample you have and what decision it supports.
| Sample type | What it helps decide | Main risk if misunderstood |
|---|---|---|
| Offer sample | Whether the coffee is interesting enough to pursue or contract | Treating a preliminary sample as a final shipment guarantee |
| Pre-shipment sample, or PSS | Whether the prepared lot should be approved before export or shipment | Approving too casually and releasing coffee that does not meet expectations |
| Arrival sample | Whether landed coffee still matches the approved quality after transit | Missing damage, age, contamination, or quality drift |
| Type sample | General example of a coffee style, grade, or profile | Assuming it represents a specific lot |
| Representative sample | A sample intended to reflect a specific lot | Failing to question whether the sample size, timing, or preparation is truly representative |
Offer Samples Show Buying Interest
An offer sample is usually used near the beginning of the buying process. It helps you decide whether a coffee fits your menu, blend plan, customer needs, and target price.
Approval at this stage may mean “we want to move forward,” not “we approve the final lot for shipment.” If the coffee is still being milled, sorted, or prepared, you may need a later representative sample before final approval.
Pre-Shipment Samples Control Release Risk
A pre-shipment sample, often called a PSS, is checked before the coffee ships. This is one of the most important approval points because approval may allow export preparation, container booking, or shipment release to proceed.
For a PSS, compare the sample against the contract and any retained offer or reference sample. Do not chase exact flavor wording too aggressively. Coffee is agricultural, so descriptors can move. But defects, major quality loss, or a mismatch in grade or profile should be taken seriously.
Arrival Samples Confirm What Landed
An arrival sample is pulled after coffee reaches the destination warehouse. It helps confirm that the coffee survived transit and still matches the approved quality.
This step matters because approval before shipment does not eliminate logistics risk. Moisture exposure, poor storage, torn bags, contamination, or long delays can affect the coffee. Arrival approval protects the buyer, but it also protects the supplier from vague complaints by grounding feedback in documented evidence.
SAS and Approval Clauses Need Plain Language
Contracts may include sample approval terms such as subject to approval of sample, subject to approval of pre-shipment sample, subject to approval of arrival sample, or similar clauses. Different traders, importers, and regions may use slightly different abbreviations.
The practical point is simple: know when your approval right applies, what sample it applies to, and what happens if the sample fails. A “no approval, no sale” understanding is very different from a courtesy sample after the commercial commitment is already firm.
If the clause is unclear, ask before contracting. It is much easier to clarify approval rights before there is a disagreement.
Begin with the final product. Is this coffee a standalone single origin, a seasonal filter feature, an espresso component, a house blend base, a wholesale workhorse, or a price-sensitive slot that needs reliability above complexity? Each use calls for a different definition of success.
Then define the minimum quality expectations. For sensory review, those may include sweetness, clean cup, acidity style, body, balance, finish, and absence of specific defects.
Also name the non-negotiables before anyone starts tasting. Common red flags include moldy, phenolic, sour, stale, papery, stewed, fermenty, chemical, baggy, or harshly astringent notes. A single odd cup may require re-cupping. A repeatable defect across cups is a different matter.
Physical targets should be included when available. These may include defect count, moisture, water activity, screen size, density, appearance, bag condition, or specific contract requirements. Not every roastery has a full green grading lab, but even basic observations are better than relying only on flavor memory.
The key is separating normal variation from disqualifying quality loss. A coffee may shift from “peach” to “stone fruit” and remain fully acceptable. But if a clean, sweet offer sample becomes flat, papery, and phenolic at PSS, that is not just a wording change.
A weak process can make a good coffee look bad. It can also make a marginal coffee seem acceptable. Treat sample preparation as part of the approval decision, not as a separate lab chore.
Log and Store the Sample
When a sample arrives, record the basics: sample ID, supplier, exporter or importer, farm, cooperative, mill, or lot information when available, contract or offer reference, sample type, date received, sample weight, packaging condition, and any visible issue on arrival.
Store green samples away from moisture, heat, odors, and direct sunlight. Coffee can absorb smells and shift in condition, especially in small sample quantities. If you may need to re-cup or dispute a result, keep enough green sample aside as a retained reference.
Control the Sample Roast
Use a consistent sample roast method. Record the roast date, equipment, batch size, roast color or development target, and any irregularities.
Sample roasting is not production roasting. The goal is not to create a finished retail profile. The goal is to reveal the coffee clearly and consistently enough for comparison. If one sample is underdeveloped and another is pushed darker, your approval results will say more about roasting than green quality.
Rest samples consistently before cupping. If your team cups most samples after a set rest period, keep that habit for approvals too.
Cup in Repeatable Conditions
Controlled cupping does not need to feel rigid, but it does need to be repeatable. Keep dose, grind, water, temperature, steep time, number of cups, and tasting order consistent.
Use multiple cups per sample when possible. One cup can hide a defect or exaggerate it. Multiple cups give you a better view of uniformity and risk.
When the decision is important, include more than one cupper. Calibration helps as well. A short conversation before final scoring can reveal whether the team agrees on the coffee or whether one person is reacting to a roast issue, palate fatigue, or style preference.
Cupping matters, but it should not be the only approval step. A defensible decision combines physical inspection, sensory evaluation, and comparison against the right reference.
Physical Inspection
Before roasting, look at the green coffee carefully. You are checking whether the sample appears sound, consistent, and aligned with the lot description.
Watch for foreign material, insect damage, broken or crushed beans, black, sour, or discolored beans, mold or suspicious residue, water marks, uneven preparation, unusual odor, signs of contamination, packaging damage, or sample leakage.
If you have the tools, measure moisture and water activity. These readings help identify storage risk and can explain why a coffee tastes flat, aged, or unstable. They also give you objective data if a dispute develops.
Photos are useful when there is visible damage. Take clear images of the sample packaging, green coffee, and any defect concentration. Do not rely on memory.
Sensory Evaluation
On the cupping table, assess both quality and fit. Useful categories include fragrance and aroma, flavor, aftertaste, acidity, body or mouthfeel, sweetness, balance, clean cup, uniformity, and defects.
Scores can help, but they are not enough alone. Write notes that explain the decision. “Approved, 84” is weaker than “Approved for espresso component: clean, sweet, medium body, mild citrus acidity, cocoa finish, no defect across five cups.”
If the coffee fails, be just as specific. “Rejected, bad” is not useful. “Rejected after re-cup: repeatable phenolic note in three of five cups, harsh finish, does not match approved offer sample” gives the supplier something concrete to investigate.
Compare Against the Right Reference
The comparison depends on the stage.
For an offer sample, compare against your product need and price expectation. For a PSS, compare against the contract, offer sample, and lot description. For an arrival sample, compare against the approved PSS or retained reference.
Do not expect exact duplication. Coffee changes with time, handling, and sample preparation. But the quality band should make sense. The coffee should still be recognizable in profile, grade, and commercial purpose.
The coffee sample approval process should not have only two buttons. Many real decisions sit between approval and rejection, and your SOP should give the team room to handle them without confusion.
Approve When the Sample Meets the Job
Approve when the sample meets contract specs, fits the intended product, and shows no unacceptable quality risk. Send approval with the sample type, lot reference, date, and responsible person.
For example: “PSS approved for lot X, cupped on July 23, approved for shipment.” Keep it clear and traceable.
Re-Cup When the Result May Be Unfair
Re-cup when something in your own process may have affected the result. Common reasons include uneven sample roast, incorrect grind, stale roast, water issue, too few cups, cupper disagreement, or possible sample mishandling.
Re-cupping is not avoidance. It is quality control. If a major commercial decision depends on the result, one questionable table should not carry the whole weight.
Request a Replacement Sample When Representation Is Doubtful
Ask for a replacement sample when the sample is damaged, too small, too old, poorly labeled, inconsistent with lot information, or visibly compromised.
This is different from rejecting the coffee. You are saying the sample cannot support a fair decision. Keep the request factual and polite.
Reject When the Problem Is Clear and Repeatable
Reject when defects, quality loss, or contract mismatch are clear and repeatable. The stronger your documentation, the cleaner this conversation becomes.
Good rejection language separates quality from changing business needs. Do not reject a coffee because the market moved, a customer backed out, or your menu changed. Those are commercial problems, not quality failures. If you need to renegotiate, be honest about that.
Conditional approval can be useful, but use it carefully. Spell out what must be confirmed before release, such as a replacement PSS, corrected documentation, additional lot information, or arrival sample confirmation.
Documentation is not busywork. It prevents confusion, helps suppliers improve, and protects both sides if the coffee later becomes disputed.
At minimum, record the sample type, lot number, contract number or offer reference, supplier, exporter, importer, or producer, date received, date roasted, date cupped, cuppers, roast approach, score or quality assessment, tasting notes, defects or concerns, physical readings when available, decision, person responsible for approval, and the date approval or rejection was sent.
Keep photos when there are visible defects, damaged packaging, bag issues, water marks, or contamination concerns.
Send feedback that is useful, not theatrical. A producer, exporter, or importer can work with notes like “clean and sweet, but lower acidity than offer sample” or “repeatable baggy note on arrival.” They cannot do much with vague disappointment.
Retain green samples and records until the arrival sample is approved and the commercial risk has passed. For important contracts, keep records longer according to your internal policy.
PSS approval often feels like the finish line, but it is really a handoff from quality control to logistics.
Once approval is sent, the supplier, exporter, producer, importer, and logistics team may need to coordinate the next steps. Shipping instructions may be issued or finalized. The exporter may book container space or prepare export documents. The coffee may move through milling, bagging, container loading, vessel transit, port arrival, customs or regulatory checks, drayage, warehouse unloading, and inventory receiving.
Delays can come from container availability, vessel changes, port congestion, holidays, documentation issues, inspections, trucking schedules, or warehouse timing. None of that reduces the importance of approving quickly and clearly. A slow or ambiguous approval can make logistics harder.
After the coffee lands, do not skip the arrival sample. This is your chance to confirm that the approved quality made it through the trip.
Here is a practical SOP your team can adapt:
- Confirm sample type and commercial decision.
- Log supplier, lot, contract, sample date, and received condition.
- Store the sample properly before roasting.
- Set approval criteria based on contract and product use.
- Inspect green coffee for physical defects or warning signs.
- Sample roast consistently and record roast details.
- Cup under controlled conditions with enough cups and cuppers.
- Compare results against the correct reference.
- Decide: approve, re-cup, request replacement, conditionally approve, or reject.
- Document the decision and send clear feedback.
- Retain samples and records through arrival approval.
This workflow does not remove judgment. It makes judgment easier to defend.
It depends on sample type and team capacity, but approvals should be handled promptly, especially for pre-shipment samples. Delayed PSS approval can slow booking, export preparation, and shipment timing. Build internal deadlines so samples are roasted, cupped, and answered before they become a logistics bottleneck.
Can one coffee sample be used for more than one approval stage?
Sometimes, but only if timing, lot status, and representation are clear. An offer sample may also act as a reference sample. A PSS may become the comparison point for arrival approval. The risk is assuming a sample represents a stage it was never meant to represent.
Should every roaster use formal cupping scores?
Scores are helpful, especially for shared records, but they are not enough. A clear pass/fail decision with tasting notes, physical observations, and intended use is often more useful than a number with no context.
What should I do if one cup shows a defect and the others do not?
Do not ignore it, but do not overreact immediately. Re-cup if the decision matters. Check whether the issue repeats across cups or appears tied to one bean, one bowl, or one preparation error. Repeatable defects carry more weight than a single unexplained cup.
When should a wholesale buyer ask for help with sample approvals?
If your team is moving from occasional buying into regular wholesale sourcing, it helps to work with suppliers who understand sample stages, approval timing, and lot consistency. For teams evaluating roasted coffee for wholesale programs, MR.VIET can be a practical next conversation: share your target profile, volume needs, and approval timeline, then request the right sample for that buying stage.
