Buyer guide · reviewed 23 July 2026
Beans, ground blends, concentrate and ready-to-drink coffee are different procurement projects. Start with the sellable format, then connect the Vietnamese coffee to extraction, filtration, preservation, packaging and evidence.
Direct answer
Define the product first
A roaster buying green Robusta for local extraction does not need the same supplier, documents or logistics as a distributor buying shelf-stable cans. Even “cold-brew concentrate” is incomplete until strength, dilution, filtration, preservation and storage are defined.
GreenTech’s role is to specify and source the Vietnamese coffee component, help map suitable processing routes, identify evidence gaps and keep lot identity connected across handoffs. Finished beverage capability is confirmed against the named facility and SKU.
Route comparison
A lower unit price can conceal extra processing, cold storage or validation work. Compare complete operating routes rather than product names.
A
Roasters, cafés and beverage manufacturers that control grinding and extraction.
Define in the RFQ
Origin, species, blend, roast, resting period, grind reference, sensory target and shipment format.
Commercial boundary
The coffee supplier does not own extraction yield, filtration, beverage safety or finished shelf life.
B
Foodservice operators and private-label brands that want a repeatable brewing input.
Define in the RFQ
Dose, particle distribution, filter or bag construction, brew ratio, water, time, temperature and outer barrier pack.
Commercial boundary
Grind drift and oxygen exposure can change extraction before the operator opens the pack.
C
RTD formulators, café chains and industrial users that will dilute or blend before sale.
Define in the RFQ
Coffee basis, extraction process, TDS or Brix method, dilution target, filtration, preservation, pack and storage.
Commercial boundary
“Concentrate” does not describe strength, microbiological status or whether cold transport is required.
D
Retail and foodservice programs that can maintain a documented cold chain.
Define in the RFQ
Formula, serving strength, process, fill hygiene, temperature limits, package, supported use-by period and transport monitoring.
Commercial boundary
Refrigeration is a control—not proof that the product is safe for an arbitrary duration.
E
Retail brands and distributors buying consumer-ready cans, bottles or cartons for unrefrigerated distribution before opening.
Define in the RFQ
Formula, equilibrium pH and water activity where relevant, validated process, closure controls, destination filings, shelf life and case configuration.
Commercial boundary
Confirm the actual extraction, treatment and filling facility—not only the exporter or brand owner.
Coffee design
Approve the coffee black and in its intended use. Milk, ice, dilution, sugar and preservation can change which blend performs best.
A strong coffee signature, milk-based applications and cost-sensitive commercial blends.
What to control
Bitterness, roast development, woody or rubbery taints, extraction strength and the dilution point at which character becomes harsh.
Black RTD products and programs seeking more aromatic, fruit, cocoa or floral differentiation.
What to control
Origin and process identity, acidity balance, aroma retention through preservation and availability of consistent replacement lots.
Programs balancing strength, aroma, milk performance, target cost and year-round repeatability.
What to control
Fixed percentages or functional targets, substitution rules, retained reference, roast treatment by component and batch-to-batch sensory release.

| Sensory release | Black and intended-use evaluation, reference sample, panel method, prohibited taints and acceptance authority. |
| Preservation | Named process, operating limits, responsible facility, deviation handling and validation applicable to the SKU. |
| Microbiology | Sampling points, organisms or indicators, methods, release limits and shelf-life monitoring. |
| Package | Primary material, closure, headspace, light and oxygen protection, coding, case pack and pallet pattern. |
| Commercial basis | Pilot quantity, production and print MOQ, lead time, annual forecast, Incoterm and quote validity. |
Preservation decision
“Cold brewed” describes extraction, not finished-product safety or shelf stability. Contract for one supported preservation and distribution route.
01
The cold chain is part of the product specification.
Time and temperature controls, sanitation, sealed-pack handling, transport monitoring, date marking and a supported use-by period.
02
Name the process; do not contract only for “pasteurized.”
Scheduled or validated operating limits, worst-case product basis, responsible process authority, deviation plan and post-process controls.
03
A long shelf-life claim must follow the complete formula, process and package.
Commercial-sterility or other applicable validation, container-closure controls, incubation or release plan, storage study and destination review.
Public Vietnam supplier signals
These first-party pages confirm that a company publicly markets a relevant product or service. They do not prove the complete capability required for your SKU.
| Public source | What it supports | What remains to verify |
|---|---|---|
| Ritachi Coffee Factory | Its first-party ingredient page says it custom roasts whole-bean or ground coffee for RTD and cold-brew concentrate programs and publishes bulk-order information. | Cold-brew grind distribution, roast tolerance, extraction reference, legal entity and facility, current certificate scope and whether the offer stops at the coffee ingredient. |
| Interfresh Co., Ltd. | Its first-party coffee-drinks page lists cold-brew products and welcomes OEM/private-label projects, with public statements on can formats, MOQ, lead time and factory certifications. | SKU-specific formula, extraction method, preservation process, certificate scope, process validation, actual MOQ and destination-label support. |
| Nam Viet Foods & Beverage JSC (VINUT) | Its own product page publishes a canned almond cold-brew coffee and describes private-label capability, packaging, shelf life and a product MOQ. | Whether the target formula is cold extracted, the responsible line and process, coffee percentage, supporting shelf-life study, documents and MOQ for custom artwork. |
| ANV IMPEX JSC | Its first-party B2B page markets Vietnam coffee concentrate in aseptic bag-in-box or drum programs and asks buyers to confirm scope, volume and destination. | Manufacturing facility, extraction and preservation owner, actual TDS or Brix specification, microbiological limits, certificate holder, pack size and lot evidence. |
| Nawon Food and Beverage Co., Ltd. | Its first-party coffee-drink page markets OEM/ODM RTD coffee and several cold-brew or cold-press SKUs in cans, glass and PET. | Technical meaning of “cold brew” or “cold press,” numeric MOQ, coffee input, extraction, filtration, preservation, microbiological controls and shelf-life evidence. |

Request a supplier reviewQualification workflow
Decide whether the quotation is for coffee input, brew pack, concentrate or consumer-ready beverage. Do not compare prices across formats.
Name who roasts, grinds, extracts, filters, formulates, preserves, fills, tests, releases and exports the SKU.
Evaluate the product black and in its intended use. Record dilution, serving temperature, milk or flavor additions and sensory limits.
Connect the actual formula and package to microbiological, chemical, sensory and transport evidence.
Set lot coding, sampling, release limits, retained samples, deviation handling and notification before any coffee, process or packaging change.
