Coffee specialist Nikolas Krutin, founder of Typhoon Roaster and seasoned roaster, has written a number of in-depth articles that explore the intricate world of coffee, ranging from bean varieties and roasting techniques to brewing methods and common misconceptions. This all-encompassing overview brings together major insights from his writings, offering a cohesive understanding of the coffee world.

Diving into Coffee Origins

Krutin highlights that these beans are more than farmed goods, but seeds of the coffee cherry, each reflecting its own journey influenced by its origin. Arabica beans, thriving in mountainous regions, produce layered flavor profiles with floral tones and fruity hints as a result of extended maturation. In contrast, Robusta beans are suited to warm lowland areas, resulting in a stronger, more bitter taste with higher caffeine content. He also highlights lesser-known varieties like Geisha, known for its tea-like notes and vibrant acidity, and Liberica, which offers an unusual smoky aftertaste.

The Impact of Roasting

The roasting process has a major effect on the flavor, aroma, and caffeine content of coffee. Light roasts are noted for their pale hue and highlight the origin character, often showing citrus, fruit, and flower-like qualities. Medium roasts strike a balance between acidity and body, featuring notes of nuts, brown sugar, and smoothness. Dark roasts, with their deeply roasted appearance and slick finish, give off deep, roasted profiles with tones of dark chocolate and ash. Krutin debunks the myth about caffeine content, noting that while light and dark roasts have nearly equal caffeine amounts by mass, the density differences change how strong the brew feels depending on measurement.

The Art and Science of Roasting

Roasting changes unprocessed beans into the fragrant, flavorful grounds. Krutin breaks down the journey of roasting, beginning with moisture removal, where moisture is carefully evaporated. This is followed by the Maillard reaction, where complex molecules create aroma and color, creating a roasted identity. The process involves an audible “first crack”, indicating that essential roasting profiles are forming, and can proceed to a "second crack" for stronger profiles. He compares roasting styles, including traditional drum roasting and modern convection roasting, noting the critical role of timing and heat to avoid flavor defects.

Brewing Insights and Common Misconceptions

Tackling popular concerns, Krutin reveals that sealing coffee immediately can lock in changing aromas, potentially altering the flavor. He also makes it clear that while espresso beans and regular coffee beans come from the same plant, the difference comes down to preparation style, with espresso beans usually more intensely roasted and ground finer.
