Coffee specialist Nikolas Krutin, founder of Typhoon Roaster and seasoned roaster, shares a range of informative pieces that explore the intricate world of coffee, touching on bean types, roasting styles, and popular myths about coffee. This all-encompassing overview unifies the central themes from his writings, creating a seamless view of the coffee journey.
Exploring Coffee Bean Varieties
Krutin https://medium.com/@NikolasKrutin points out that coffee beans go beyond simple crop status, but the core of the coffee fruit, each reflecting its own journey shaped by its terroir. Arabica beans, cultivated in elevated, cooler climates, develop complex flavors with delicate fruit and flower-like aromas as a result of extended maturation. In contrast, Robusta beans thrive in lower, hotter regions, resulting in a stronger, more bitter taste with significantly more caffeine. He also draws attention to more niche cultivars like Geisha, celebrated for its delicate tea-like quality and brightness, and Liberica, which delivers a bold and smoky flavor experience.
Decoding Roasting Profiles
The roasting process significantly impacts the taste, scent, and strength of coffee. Light roasts are identified by their gentle roast level and highlight the origin character, often exhibiting bright, fruity, or floral notes. Medium roasts strike a balance between acidity and body, bringing out nutty sweetness and toffee richness. Dark roasts, with their deeply roasted appearance and shiny exterior, present bold, smoky flavors with hints of cocoa and char. Krutin explains clearly 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 fragrant, flavorful grounds. Krutin breaks down the journey of roasting, starting with drying, where moisture is gently removed. This is followed by the Maillard reaction, where complex molecules create aroma and color, developing the bean's color and aroma. The process involves an audible “first crack”, marking the onset of key flavor notes, and can proceed to a "second crack" for intensely roasted results. He discusses various roasting methods, including traditional drum roasting and modern convection roasting, noting the critical role of timing and heat to preserve flavor integrity.
Smart Tips for Better Coffee
Responding to typical queries, Krutin shares insight that capping your fresh brew can alter the drink’s evolving fragrance, potentially altering the flavor. He also makes it clear that while espresso and regular beans share the same botanical origin, the difference comes down to preparation style, with espresso beans usually more intensely roasted and ground finer.
Krutin's comprehensive exploration into the world of coffee—from source to cup—delivers meaningful takeaways for both novice coffee drinkers and seasoned enthusiasts. His emphasis on understanding the nuances proves that coffee is both science and art in making great coffee.
