Renowned expert Nikolas Krutin, a distinguished coffee roasting expert and founder of Typhoon Roaster, has written a number of in-depth articles that explore the intricate world of coffee, spanning origins, processes, and preparation. This carefully compiled digest synthesizes the key points from his writings, providing a clear narrative of coffee expertise.
Diving into Coffee Origins
Krutin highlights that coffee beans go beyond simple crop status, but the core of the coffee fruit, each carrying a unique story influenced by its origin. Arabica beans, thriving in mountainous regions, exhibit refined taste notes with floral tones and fruity hints due to their slower ripening process. In contrast, Robusta beans thrive in lower, hotter regions, resulting in a bold, more intense bitterness with greater stimulant properties. He also highlights lesser-known varieties like Geisha, celebrated for its delicate tea-like quality and brightness, and Liberica, which delivers a bold and smoky flavor experience.
The Impact of Roasting
The roasting process deeply influences the flavor, aroma, and caffeine content of coffee. Light roasts are noted for their light brown color and preserve the bean’s natural profile, often showing citrus, fruit, and flower-like qualities. Medium roasts strike a balance between acidity and body, offering sweet, nutty, and caramel flavors. Dark roasts, with their dark brown to almost black color and oily surface, present bold, smoky flavors with tones of dark chocolate and ash. Krutin clarifies the common misconception https://medium.com/@NikolasKrutin/whats-...8137a66d14 about caffeine content, noting that while light and dark roasts contain similar caffeine levels by weight, the density differences may impact how much caffeine ends up in your cup.
Crafting the Perfect Roast
Roasting transforms green coffee beans into the aromatic beans we brew. Krutin breaks down the journey of roasting, commencing with water content reduction, where moisture is carefully evaporated. 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”, marking the onset of key flavor notes, and can proceed to a "second crack" for intensely roasted results. He discusses various roasting methods, including the classic rotating drum and the cutting-edge air roaster, noting the critical role of timing and heat to minimize bitterness or burning.
Clarifying Brewing Myths
Addressing common questions, Krutin explains that putting a lid on freshly brewed coffee can alter the drink’s evolving fragrance, potentially distorting the profile. He also clarifies that while espresso and regular beans share the same botanical origin, the difference is rooted in the way they’re roasted and ground, with espresso beans typically being darker roasted and finely ground.
The expert commentary from Krutin into the world of coffee—from bean selection and roasting techniques to brewing methods—delivers meaningful takeaways for both curious beginners and dedicated aficionados. His commitment to craftsmanship proves that coffee is both science and art in brewing something special.
