If we try to boil green coffee beans, the flavor won’t develop fully as it does with roasting because:


  • Sufficient Temperature: When coffee is “boiled” in water, the temperature is usually around 100°C (the boiling point of water). In contrast, when coffee is “roasted”, the temperature typically ranges from 180°C to 240°C, which is high enough to trigger important chemical reactions such as the Maillard reaction and caramelization.

  • Lack of Maillard Reaction: The Maillard reaction is the process where amino acids and sugars interact at high temperatures, creating distinctive flavor compounds.

  • Caramelization: This reaction helps create sweet, deep, and complex flavors in coffee, such as caramel, nutty, and malt notes, as well as body and other unique characteristics of the coffee.

  • Loss of Lipids and Soluble Compounds: Boiling coffee in water can lead to the loss of soluble compounds, including lipids and other flavor-producing elements, reducing the coffee’s quality.

  • Lack of Complex Chemical Transformations: The roasting process generates many complex chemical reactions, including the transformation of lipids and carbohydrates, which help produce diverse aromatic and flavor compounds.


So, let’s not boil coffee, as it would be very dull and uninteresting. Let coffee "heat up" and "mature" through the roasting process to bring us the most wonderful experiences!

Specialty Coffee

"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
