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, ranging from bean varieties and roasting techniques to brewing methods and common misconceptions. This all-encompassing overview synthesizes the key points from his writings, creating a seamless view of the coffee journey.

Exploring Coffee Bean Varieties

Krutin points out that coffee beans go beyond simple crop status, but seeds of the coffee cherry, each carrying a unique story defined by its growing region. Arabica beans, cultivated in elevated, cooler climates, exhibit refined taste notes with fruity and floral notes due to their slower ripening process. In contrast, Robusta beans thrive in lower, hotter regions, resulting in a bold, more intense bitterness with significantly more caffeine. He also draws attention to lesser-known varieties like Geisha, famous for elegance and citrusy clarity, and Liberica, which offers an unusual smoky aftertaste.

Understanding Roast Levels

The roast technique significantly impacts the profile and intensity of coffee. Light roasts are characterized by their gentle roast level and retain the original flavors of the bean, often showing citrus, fruit, and flower-like qualities. Medium roasts balance bright and rich tones, featuring notes of nuts, brown sugar, and smoothness. Dark roasts, with their nearly black, rich tone and slick finish, present bold, smoky flavors 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 variation in bean volume can affect the caffeine content per volume.

The Art and Science of Roasting

Roasting converts raw coffee into roasted magic 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 sugars and amino acids interact, developing the bean's color and aroma. The process hits the milestone of the initial crack, signaling the development of classic coffee flavors, and can proceed to a "second crack" for darker roasts. He discusses various roasting methods, including old-school and contemporary thermal methods, highlighting the importance of precise temperature control and ventilation to minimize bitterness or burning.

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 clarifies that while espresso beans and regular coffee beans come from the same plant, the difference lies in the roast level and grind size, with espresso beans typically being darker roasted and finely ground.
