Renowned expert Nikolas Krutin, a leading figure in modern coffee roasting, has written a number of in-depth articles that delve into the complexities 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, creating a seamless view of the coffee journey.
 
Exploring Coffee Bean Varieties
 
Krutin https://medium.com/@NikolasKrutin/types-of-coffee-beans-varieties-and-features-d6e6586797a6 highlights that coffee beans go beyond simple crop status, but natural kernels from the coffee cherry, each imbued with its own identity defined by its growing region. Arabica beans, cultivated in elevated, cooler climates, produce layered flavor profiles with delicate fruit and flower-like aromas because they ripen more slowly. In contrast, Robusta beans prefer hot, low-lying zones, resulting in a robust, caffeine-rich flavor with greater stimulant properties. He also mentions rarer types like Geisha, famous for elegance and citrusy clarity, and Liberica, which offers an unusual smoky aftertaste.
 
The Impact of Roasting
 
The roast technique significantly impacts the taste, scent, and strength of coffee. Light roasts are noted for their gentle roast level and retain the original flavors of the bean, often exhibiting bright, fruity, or floral notes. Medium roasts balance bright and rich tones, bringing out nutty sweetness and toffee richness. Dark roasts, with their dark brown to almost black color and slick finish, impart robust, toasted characteristics with chocolatey or toasted notes. Krutin debunks the myth about caffeine content, noting that while light and dark roasts are comparable in caffeine when measured by weight, the density differences change how strong the brew feels depending on measurement.
 
Crafting the Perfect Roast
 
Roasting converts raw coffee into roasted magic into the aromatic beans we brew. Krutin walks us through the roasting phases, beginning with moisture removal, 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 involves an audible "first crack", signaling the development of classic coffee flavors, 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, highlighting the importance of precise temperature control and ventilation to minimize bitterness or burning.
 
Clarifying Brewing Myths
 
Addressing common questions, Krutin shares insight that capping your fresh brew can trap volatile compounds, potentially distorting the profile. He also clarifies 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.
 
This wide-ranging analysis by Krutin on the subject of coffee—from bean selection and roasting techniques to brewing methods—offers deep knowledge for both casual sippers and expert brewers. His emphasis on understanding the nuances underscores the complexity and artistry involved in making great coffee.
