To truly appreciate the role of a master coffee roaster, it’s essential to understand the journey of a coffee bean. The journey begins with the coffee plant, primarily grown in tropical and subtropical regions. Here’s a closer look at crucial stages before the roasting process begins:
1. Cultivation
Coffee berries grow on coffee plants, which typically reach maturity after about three to four years. Key factors influencing the cultivation process are:
- Geography: The altitude and climate of the region affect the bean’s flavor characteristics. Coffee from high altitudes generally has a unique acidity and complex flavors.
- Varietals: Different coffee plant species—and even varieties within those species—offer a broad range of flavor profiles.
2. Harvesting
Once the coffee cherries reach maturity, they are harvested. There are two primary methods of harvesting: selective picking and strip picking. Selective picking involves carefully choosing ripe cherries, whereas strip picking collects all cherries at once, regardless of ripeness.
3. Processing
Processed coffee varies in flavor and quality based on the method used, which can include:
- Dry Processing: The cherries are spread out to dry in the sun, allowing the natural sugars to infuse into the beans.
- Wet Processing: This method involves fermenting the cherries to remove the pulp, leading to a cleaner flavor.
After processing, the beans are hulled, sorted, and graded before being exported as green coffee beans.
The Roasting Process
Roasting transforms green coffee beans into the aromatic, rich beans we know and love. The roasting process involves a complex interaction of heat, time, and moisture, which can significantly alter the properties of the beans.
Key Stages of Roasting
Drying Phase: The moisture in the green beans is eliminated, generally occurring at temperatures between 150°F and 180°F (65°C and 82°C).
Maillard Reaction: This crucial stage begins once the beans reach about 300°F (150°C). The amino acids and sugars react, leading to the development of color and flavor. This phase is bit like the toasting of bread—creating browning and caramelization.
First Crack: As the beans expand and release steam, they often make a cracking sound. This signals the beginning of the first roast level, which typically results in a light to medium roast.
Development Phase: Post-crack, the roaster can choose to develop the coffee further. This is where a master coffee roaster’s artistry comes into play; they decide how long to roast to achieve the desired flavor profile.
Second Crack: Not all beans reach this stage. For darker roasts, the second crack occurs when the beans reach higher temperatures (about 440°F / 227°C). Here, oils and deep flavors emerge, often resulting in a more bitter taste.
Cooling: Rapid cooling ensures that the roasting process stops, preserving the flavors achieved during roasting. Master roasters must cool the beans quickly to capture their ideal characteristics.
