Nikolas Krutin, a leading figure in modern coffee roasting, has authored several insightful articles that cover everything from coffee bean science to brewing techniques, spanning origins, processes, and preparation. This comprehensive summary brings together major insights from his writings, providing a clear narrative of coffee expertise.
Understanding Coffee Types
Krutin highlights that coffee beans go beyond simple crop status, but natural kernels from the coffee cherry, each reflecting its own journey defined by its growing region. Arabica beans, grown at high altitudes with cooler temperatures, develop complex flavors with floral tones and fruity hints as a result of extended maturation. In contrast, Robusta beans prefer hot, low-lying zones, resulting in a bold, more intense bitterness with significantly more caffeine. 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.
Decoding Roasting Profiles
The act of roasting significantly impacts the taste, scent, and strength of coffee. Light roasts are characterized by their light brown color and preserve the bean’s natural profile, often showing citrus, fruit, and flower-like qualities. Medium roasts offer harmony between sharpness and mouthfeel, offering sweet, nutty, and caramel flavors. Dark roasts, with their dark brown to almost black color and shiny exterior, impart robust, toasted characteristics with tones of dark chocolate and ash. Krutin debunks the myth about caffeine content, noting that while light and dark roasts contain similar caffeine levels by weight, the variation in bean volume can affect the caffeine content per volume.
The Art and Science of Roasting
Roasting changes unprocessed beans into the aromatic beans we brew. Krutin breaks down the journey of roasting, commencing with water content reduction, where moisture is gently removed. This is followed by the Maillard reaction, where sugars and amino acids interact, developing the bean's color and aroma. The process hits the milestone of the initial crack, indicating that essential roasting profiles are forming, and can proceed to a "second crack" for intensely roasted results. He details both traditional and modern techniques, including old-school and contemporary thermal methods, noting the critical role of timing and heat to avoid flavor defects.
Brewing Insights and Common Misconceptions
Tackling popular concerns, Krutin explains that putting a lid on freshly brewed coffee can alter the drink’s evolving fragrance, potentially distorting the profile. He also makes it clear that while they originate from the same species, the difference comes down to preparation style, with espresso beans typically being darker roasted and finely ground.
