1. Rate of Rise (ROR) Control Method

- Definition: Rate of Rise (ROR) is a measure of the rate at which the temperature of the coffee beans increases during roasting, typically measured in degrees Celsius per minute.

- Goal: Maintaining a steadily decreasing ROR is a common goal to avoid issues like over-roasting and ensure a balanced flavor profile.

- Advantages: Ensuring consistency, avoiding common roasting errors, and optimizing flavor and sweetness.

- Disadvantages: Requires precision, experience, and modern equipment.

2. Analysis of Roasting Stages

The three main stages of coffee roasting as per SCA standards are correctly described:

a) Drying Phase

- Purpose: Removing moisture from the beans without causing significant temperature changes.

b) Maillard/Caramel Phase

- Purpose: Involves chemical reactions that develop complex flavors and color.

c) Development Phase

- Purpose: Starts at the first crack and determines the final flavor profile and roast degree of the beans.

- Advantages and Disadvantages: Flexibility, experimentation potential, time, and effort required, and beginner challenges.

3. Traditional Method Based on Color and Aroma

- Definition: Traditional methods relying on sensory inputs like color and aroma are accurate descriptions of artisanal roasting practices.

- Advantages: Sensory skill development and minimal equipment needs.

- Disadvantages: Dependence on experience and inconsistency in results.

4. Combined Method

- Definition: Combining various methods for optimal results, using ROR for temperature control, and sensory observations for adjustments.

- Advantages and Disadvantages: Combining the benefits, increasing flexibility and control, requiring broad knowledge, and complexity for beginners.

How to Improve Skills and Knowledge

1. Continuous Practice

- Practice: Emphasizing continuous practice to understand various factors affecting coffee flavor.

2. Continuous Learning

- Learning: Attending courses and workshops, especially those offered by SCA, reading books, and studying specialized materials.

3. Analysis and Record Keeping

- Records: Keeping detailed roast logs to track and learn from each roast session.

4. Community Engagement

- Engagement: Joining forums and social media groups for experience exchange.

5. Understanding Equipment

- Equipment: Understanding the specific roasting machine used.

6. Focus on Sensory Skills

- Sensory Skills: Developing skills to assess color, aroma, and taste for quality control.

Conclusion

Each coffee roasting method has its own advantages and disadvantages, and choosing the right method depends on personal goals and preferences. The most important thing is that the roaster must continuously learn, experiment, and improve to produce the best-tasting coffee batches. Becoming a skilled roaster requires patience, passion, and unwavering commitment to the craft.

"COVID initiated an unexpected crisis, causing the world to stall and shut down. Thus, we must live slower and capture the best moments in the darkest of times. I wondered whether my love for coffee has ripened over this period. I began devoting my time and passion towards researching the field of specialty coffee. I realized the value of coffee is more than just caffeine. It embodies a culture, a taste of different countries that diversify itself in every nation with a history of development dated back to the 19th century."

 

Slowly, the “sophisticated knowledge” I once pride myself on shattered. I had been so shortsighted and so assumptious. I never cared about where the products of my passion came from, knew nothing about growing to preliminary processing, roasting, preserving, and brewing a great cup of coffee. And I know, there are many presumptuous people all around us, just like me a few years back. They never knew what a great experience coffee could be despite it being indispensable in our lives. ​ As my appreciation for coffee reaches its peak, I feel delighted and satisfied sipping every cup of high-quality espresso extracted from Vietnam Fine Robusta beans. If you could experience every stage of the coffee value chain, from the early plantations to a cup of coffee, you will feel the same way as i do. This is the biggest motivation for us to pursue our dream of bringing high-quality Robusta beans to coffee lovers around the world. Trust me! The nature-gifted Fine Robusta that Vietnam has proudly developed shall be a great addition to your collection of specialty coffee. ​ iO Coffee looks forward to the companionship of all partners and the coffee-loving community on this wonderful journey. ​

 

Sincerely,

Ngo Huan Trung
