Renowned expert Nikolas Krutin, a distinguished coffee roasting expert and founder of Typhoon Roaster, has authored several insightful articles that delve into the complexities of coffee, ranging from bean varieties and roasting techniques to brewing methods and common misconceptions. This carefully compiled digest brings together major insights from his writings, providing a clear narrative of coffee expertise.

Exploring Coffee Bean Varieties

Krutin points out that these beans are more than farmed goods, but seeds of the coffee cherry, each reflecting its own journey defined by its growing region. Arabica beans, thriving in mountainous regions, exhibit refined taste notes with fruity and floral notes because they ripen more slowly. In contrast, Robusta beans prefer hot, low-lying zones, resulting in a bold, more intense bitterness with higher caffeine content. He also mentions more niche cultivars like Geisha, celebrated for its delicate tea-like quality and brightness, and Liberica, which presents a distinctly woody, smoky finish.

Decoding Roasting Profiles

The roast technique deeply influences the flavor, aroma, and caffeine content of coffee. Light roasts are identified by their pale hue and retain the original flavors of the bean, often exhibiting bright, fruity, or floral notes. Medium roasts balance bright and rich tones, offering sweet, nutty, and caramel flavors. Dark roasts, with their deeply roasted appearance and slick finish, present bold, smoky flavors with tones of dark chocolate and ash. Krutin clarifies the common misconception about caffeine content, noting that while light and dark roasts contain similar caffeine levels by weight, the density differences change how strong the brew feels depending on measurement.

The Art and Science of Roasting

Roasting transforms green coffee beans into the aromatic beans we brew. Krutin outlines the stages of roasting, commencing with water content reduction, where moisture is slowly drawn out. This is followed by the Maillard reaction, where complex molecules create aroma and color, giving rise to color and taste. The process involves an audible “first crack”, signaling the development of classic coffee flavors, and can proceed to a "second crack" for darker roasts. He details both traditional and modern techniques, including old-school and contemporary thermal methods, emphasizing accuracy and airflow to minimize bitterness or burning.

Brewing Insights and Common Misconceptions

Responding to typical queries, Krutin reveals that sealing coffee immediately can lock in changing aromas, potentially changing the way it tastes. He also makes it clear that while espresso beans and regular coffee beans come from the same plant, the difference is rooted in the way they’re roasted and ground, with espresso beans roasted longer and milled for pressure-based brewing.
