Roasting coffee is more than just a process; it’s an art form that transforms green coffee beans into the rich, aromatic beverage we all know and love. At Vasthare, where every bean is treated with the utmost respect, roasting is a crucial step that brings out the unique flavors and complexities hidden within each batch.

The Journey Begins with Green Beans

The journey to the perfect cup of coffee starts long before the beans reach the roaster. It begins on our 100-acre estate in Chikmagalur, where we cultivate specialty Arabica beans with care and precision. The terroir — the combination of soil, climate, and altitude — imparts distinct characteristics to our beans, but it’s the roasting process that unlocks these flavors.

Green coffee beans are essentially raw, and while they contain the potential for great flavor, they lack the aroma and taste that make coffee so irresistible. Roasting is the process that unlocks these qualities, using heat to bring about a series of chemical reactions within the beans.

The Roasting Process: A Dance of Time and Temperature

Roasting coffee is a delicate balance between time and temperature. Every batch of beans is different, requiring the roaster to adjust the process to suit the specific characteristics of the beans. Too much heat too quickly can scorch the beans, while too little heat will result in an underdeveloped flavor. This is where the roaster’s skill and experience come into play.

The process begins with preheating the roaster to the desired temperature, usually between 370 to 540°F (188 to 282°C). The green beans are then introduced into the roaster, where they begin to absorb heat. As the temperature rises, the beans undergo several stages:

Drying Phase: The beans lose moisture and start to turn yellow. This stage lasts a few minutes and prepares the beans for the chemical transformations that follow.

Maillard Reaction: As the beans continue to heat, they enter the Maillard reaction, where sugars and amino acids react to create a rich, brown color and develop complex flavors. This is when the aroma of freshly roasted coffee begins to emerge.

First Crack: At around 385°F (196°C), the beans undergo the first crack, an audible popping sound indicating that the beans have expanded and the cell structure has begun to break down. This is a critical moment, as the beans have now reached light roast status. For some, this is the perfect stopping point to preserve the bean’s original flavors.

Development Phase: The roaster can choose to extend the roast to develop deeper flavors, leading to medium and dark roasts. This phase requires careful monitoring, as the beans can quickly go from perfectly roasted to burnt if not watched closely.

Second Crack: At around 435°F (224°C), a second crack may occur. This indicates that the beans are entering the dark roast phase. The sugars begin to caramelize, and oils rise to the surface, giving the beans a glossy appearance. Dark roasts are known for their bold, smoky flavors but must be handled with care to avoid bitterness.

The Role of the Roaster

A skilled roaster understands that no two batches are the same. Each requires a tailored approach to bring out the best in the beans. This understanding of the delicate interplay between time, temperature, and bean characteristics is what elevates roasting from a mere process to an art.

At Vasthare, we take pride in the precision and attention to detail that our roasters bring to each batch. We believe that the art of roasting is about more than just following a set of instructions; it’s about understanding the potential of each bean and coaxing out the flavors that make it truly unique.

The Final Product: A Symphony of Flavors

The result of a well-executed roast is a coffee that is full of character, with layers of flavor that reflect the care and craftsmanship that went into its creation. Whether you prefer the bright, fruity notes of a light roast or the deep, chocolatey richness of a dark roast, the art of the roast is what makes each cup of coffee a sensory experience.

From the moment the beans are harvested to the final sip of your morning brew, every step in the process is a testament to the dedication and expertise of those who craft it. The next time you enjoy a cup of Vasthare coffee, take a moment to appreciate the journey it has taken — from the green hills of Chikmagalur to the skilled hands of our roasters, who have mastered the art of the roast.
