Coffee roasting companies – New standards and processes

Operating a coffee roasting company requires not only technical expertise but also meticulous attention to detail in each stage, from sourcing, roasting, to testing and storage. This ensures that every cup of coffee delivers the best possible flavor experience to the consumer.

Coffee sourcing 

The sourcing process for coffee at roasting companies goes beyond just purchasing raw materials; it involves a strict selection process. Roasters often work directly with farmers or cooperatives, carefully inspecting farming conditions, harvest methods, and bean processing techniques. Important criteria include the altitude of the growing region, drying and fermentation methods, and the harvest time. Only beans that meet quality and flavor standards are chosen.

Roasting 

At roasting companies, coffee roasting is carried out by experts with deep knowledge and experience. Roasting involves more than simply heating beans; it requires a series of controlled and carefully monitored steps:

• Selecting the roast profile: This term refers to the precise time and temperature settings for each specific coffee. Depending on the bean’s structure, variety, and flavor requirements, the roasters experiment and choose the most suitable parameters to meet their goals.
• Controlling the roasting process: The temperature, time, and cooling speed are continuously adjusted. Modern roasting machines allow precise temperature measurement at every stage, ensuring the beans undergo the desired chemical transformations to produce the preferred flavor. Machines with capacities ranging from 5kg to 60kg are used to ensure consistency.

Brewing and testing 

Brewing and tasting are vital steps to evaluate the success of the roasting process. Professional tasters often use the “cupping” method to assess the quality and flavor of finely ground coffee, examining factors such as aroma, sweetness, acidity, and aftertaste. Large specialty coffee suppliers usually employ certified tasters (Q-graders) to ensure they have the skills to detect subtle characteristics in each coffee sample. Tasting dozens of samples per day, they adjust roasting methods or decide which coffees to bring to market.

Packaging and storage 

Proper packaging is essential to preserving coffee’s freshness. Coffee bags are often equipped with one-way valves to release CO2 without letting in oxygen, extending the coffee’s shelf life. Sustainable trends have led many companies to use eco-friendly packaging materials like recyclable or biodegradable GrainPro bags. After packaging, coffee is stored in temperature-controlled environments (15-25°C), with humidity below 60% and no direct exposure to light. This helps maintain freshness for several weeks or months, depending on when the coffee was roasted.

The operation of a coffee roasting company requires not only high technical skills but also meticulous attention to each stage, from sourcing, roasting, testing, to storage.

Based on scale and product type, coffee roasting companies can be categorized into different models, each with its own strengths and weaknesses depending on the market and target customer.

Small-scale Roasters 

These are typically small, family-owned businesses or startups with a focus on quality. They may have a single roasting machine with a capacity of 5kg to 30kg per batch and emphasize each coffee batch’s unique characteristics.

• Characteristics: Small-scale roasters often serve local markets or sell directly through small stores and online. They can customize the roasting process to meet specific customer preferences, such as adjusting roast levels for individual coffee shops or consumers.
• Advantages:

– Production flexibility: Small roasters can easily experiment with different roast profiles to match each type of coffee and customer preference.

– Focus on quality: With smaller production volumes, they can spend more time ensuring each batch is perfectly roasted.

– Flavor customization: They can tailor each batch to customer requests, increasing satisfaction and creating personalized experiences.

• Disadvantages:

– Limited output: Small roasters may only produce 50-300kg of coffee per week, compared to the tons produced daily by large companies.

– Price competition: Small roasters may struggle to compete on price with larger companies due to higher production costs for smaller volumes.

Large-scale roasters

• Characteristics: These companies operate on an industrial scale, capable of producing tons of coffee daily. They are usually part of global supply chains, distributing widely across large markets.
• Advantages:

– High volume production: Suitable for retail and export markets.

– Wide distribution: Products are available nationally and internationally, making them easily accessible to consumers.

– Product variety: From specialty coffee to everyday blends, they cater to a broad range of customer preferences.

• Disadvantages:

– Lack of uniqueness: Mass production may result in less distinctive coffee flavors compared to small-scale roasters.

– Limited customization: Large companies may not be able to offer personalized products for individual customers or small coffee shops.

Specialty Coffee roasters

Specialty coffee roasters focus on roasting high-quality beans that meet the demands of coffee connoisseurs. These companies often use high-end roasting equipment and manual processes, dedicating time to experimenting with temperature and roast profiles to bring out the best in each batch.

Example: XLIII Coffee, known for its expertise in specialty coffee roasting, sources beans from renowned regions like Ethiopia and Colombia. Using advanced light roasting techniques, they emphasize bright acidity and vibrant flavor notes, ensuring that the coffee’s original characteristics are preserved.

Coffee roasting companies play a crucial role in developing Vietnam’s coffee industry through three key areas:

Preserving and enhancing local coffee flavors: Roasters contribute to the growth of native coffee varieties, adding value to Vietnamese coffee on the global stage.

Collaborating with farmers: Roasters work closely with farmers to improve cultivation, harvesting, and processing methods, raising the quality of raw beans. Training programs and technical support enable farmers to adopt more sustainable practices like UTZ or 4C standards.

Example: Bosgaurus Coffee Roaster collaborates with farms in the Central Highlands to promote environmentally friendly farming practices and enhance the quality of coffee beans.

Product diversification: Roasters help create new coffee products to meet diverse market demands. By blending beans from different regions or adding natural flavors, they create unique offerings for consumers.

Roasting companies play a key role in developing new coffee products to meet the diverse demands of the market.

With increasing consumer interest in quality and environmental protection, the coffee roasting industry in Vietnam is expected to evolve in line with global trends, focusing on sustainability, personalization, and technological integration.

Sustainable coffee 

Sustainability will be a major trend, with more companies incorporating clean energy and eco-friendly production methods. The use of solar power or renewable energy in roasting, alongside recyclable or biodegradable packaging, will become standard. Roasters will also prioritize partnerships with farms that practice sustainable cultivation.

Personalized products 

Consumers are increasingly seeking products tailored to their personal tastes. Roasters will offer more options for customers to customize their coffee, from roast levels to bean blends. Seasonal coffee products will also gain popularity, allowing customers to enjoy fresh, region-specific flavors throughout the year.

Technology integration ‘

Automation and smart management systems will become key to controlling the roasting process and ensuring quality. Technologies like blockchain will enable full traceability of coffee beans, and market demand forecasting will optimize production and distribution.

Conclusion

Coffee roasting companies are vital to enhancing the quality and value of specialty coffee. They serve as a bridge between farmers and consumers, while also fostering sustainable development within the coffee industry. As trends move toward sustainability, personalization, and technological innovation, roasting companies will continue to elevate product quality and contribute to the global growth of the coffee industry.
