Lien Viet Green delivers complete OEM coffee solutions powered by certified CQI Q Graders, an ISO 22000:2018 certified facility, and strict quality control from raw beans to finished products.

In today’s competitive F&B market, OEM coffee has become a strategic choice for brands looking to launch their own products without investing heavily in roasting equipment or processing plants. However, to ensure product stability and align with brand positioning, businesses must partner with a manufacturer possessing strong capabilities in raw material sourcing, R&D, roasting technology, and quality control.
Positioned as a long-term B2B coffee supply partner, Lien Viet Green has established an end-to-end OEM ecosystem: from green coffee sourcing and sample testing to custom flavor profiling, roasting, and packaging. Our technical expertise and ISO 22000:2018 certified food safety management system allow businesses to scale with confidence.
What Is OEM Coffee and Why Should Businesses Choose It?
OEM (Original Equipment Manufacturer) in the coffee industry is a model where a manufacturer roasts, processes, and packages coffee according to the client’s specifications and brand identity. The client owns the brand, packaging design, and commercial rights, while the manufacturer manages raw sourcing, roasting curves, and packaging operations.

Enabling Brands to Develop Signature Products
Instead of reselling generic commercial coffee, OEM allows brands to formulate their own taste profiles. This is critical for cafe chains, specialty coffee shops, and retail brands that want to build a distinctive flavor identity and avoid direct price competition.
Reducing Capital Expenditure and Production Risk
Building a professional roastery requires substantial capital: commercial roasters, green bean storage systems, quality control equipment, packaging lines, and skilled roastmasters. By partnering with an established OEM provider, businesses convert high fixed capital costs into flexible operating costs, allowing them to focus resources on marketing, sales, and channel expansion.

CQI Q Grader – The Technical Foundation in Coffee Evaluation
Quality control in coffee cannot rely on subjective guessing. It requires standardized sensory analysis based on international protocols.
The Coffee Quality Institute (CQI) Q Grader certification is the global benchmark for professional coffee cupping and grading. At Lien Viet Green, our CQI Q Grader team evaluates green beans and roasted batches using Specialty Coffee Association (SCA) standard cupping forms, assessing fragrance/aroma, flavor, aftertaste, acidity, body, balance, uniformity, clean cup, and sweetness.


Why Sensory Evaluation Matters for B2B Clients
Sensory analysis helps roasters and buyers identify defects early, optimize roast profiles, and maintain consistent flavor across consecutive crop seasons.
ISO 22000:2018 Certified Food Safety Management
For F&B chains, corporate clients, hotels, and export markets, food safety certifications are mandatory criteria during supplier auditing.
Lien Viet Green operates an ISO 22000:2018 certified processing facility. Every processing step, from green bean reception, storage, roasting, cooling, and degassing to grinding, sealing, and warehouse logistics, is systematically managed under the ISO 22000:2018 food safety management system.

Lien Viet Green – Tailored OEM Solutions for Every Business Model
We approach OEM not simply as a subcontracting service, but as an integrated product development partnership:

Custom Roasted Coffee Beans and Blends
We formulate tailored coffee profiles for diverse brew methods: espresso machine blends, traditional phin filter blends, signature cold brew blends, and specialty single origins for cafes, hotels, and restaurants.


OEM Steeped Coffee Bags and Private-Label Products

Beyond whole bean and ground coffee, Lien Viet Green specializes in OEM/ODM steeped coffee bags, a convenient format ideal for hotels, resorts, modern offices, corporate gifting, and retail expansion. We handle complete customization: grind size, nitrogen-flushed foil packaging, outer box design, and brewing specifications.
Hot Air Roasting Technology Integrated with AI Monitoring
In commercial coffee manufacturing, repeatability is paramount. Lien Viet Green utilizes industrial Hot Air convection roasting combined with AI-assisted process tracking. This system monitors real-time roasting curves, Rate of Rise (RoR), and environmental temperatures to replicate target roast profiles batch after batch with minimal deviation.

From Artisan Experience to Data-Driven Consistency
While the roastmaster’s craftsmanship remains vital for initial product development, large-scale commercial production requires data. Standardized data recording reduces human error and ensures uniform cup quality across monthly delivery cycles, a crucial factor for franchise F&B chains opening new locations.
Why Partner with Lien Viet Green?
Selecting an OEM partner should not be based solely on price per kilogram. Businesses need a comprehensive evaluation of bean supply, R&D expertise, quality assurance, production capacity, and post-delivery technical support.
Five things to evaluate in an OEM partner- Bean supplyDirect sourcing from growing regions, selected by cup quality rather than name or price.
