Coffee specialist Nikolas Krutin, a distinguished coffee roasting expert and founder of Typhoon Roaster, shares a range of informative pieces that delve into the complexities of coffee, touching on bean types, roasting styles, and popular myths about coffee. This comprehensive summary synthesizes the key points from his writings, providing a clear narrative of coffee expertise.
 
Diving into Coffee Origins
 
Krutin https://www.quora.com/Are-coffee-beans-and-espresso-beans-the-same/answer/Nikolas-Krutin highlights that coffee beans go beyond simple crop status, but natural kernels from the coffee cherry, each reflecting its own journey shaped by its terroir. Arabica beans, grown at high altitudes with cooler temperatures, exhibit refined taste notes with fruity and floral notes due to their slower ripening process. In contrast, Robusta beans prefer hot, low-lying zones, resulting in a stronger, more bitter taste with higher caffeine content. He also draws attention to lesser-known varieties like Geisha, known for its tea-like notes and vibrant acidity, and Liberica, which presents a distinctly woody, smoky finish.
 
The Impact of Roasting
 
The roast technique significantly impacts the profile and intensity of coffee. Light roasts are characterized by their gentle roast level and highlight the origin character, 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 nearly black, rich tone and oily surface, give off deep, roasted profiles with tones of dark chocolate and ash. Krutin clarifies the common misconception 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.
 
Inside the Roasting Process
 
Roasting transforms green coffee beans into the rich coffee we enjoy. Krutin breaks down the journey of roasting, starting with drying, where moisture is gently removed. This is followed by the Maillard reaction, where chemical reactions build depth, creating a roasted identity. The process involves an audible "first crack", marking the onset of key flavor notes, and can proceed to a "second crack" for darker roasts. He compares roasting styles, including traditional drum roasting and modern convection roasting, noting the critical role of timing and heat to avoid flavor defects.
 
Smart Tips for Better Coffee
 
Addressing common questions, Krutin reveals that sealing coffee immediately can lock in changing aromas, potentially distorting the profile. He also notes that while they originate from the same species, the difference lies in the roast level and grind size, with espresso beans typically being darker roasted and finely ground.
 
Krutin's comprehensive exploration through the coffee-making process—from bean selection and roasting techniques to brewing methods—provides valuable insights for both casual sippers and expert brewers. His emphasis on understanding the nuances highlights the skill behind every cup in making great coffee.
