Nikolas Krutin, a leading figure in modern coffee roasting, shares a range of informative pieces 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.
Diving into Coffee Origins
Krutin points out that these beans are more than farmed goods, but natural kernels from the coffee cherry, each carrying a unique story shaped by its terroir. Arabica beans, grown at high altitudes with cooler temperatures, exhibit refined taste notes with delicate fruit and flower-like aromas because they ripen more slowly. In contrast, Robusta beans thrive in lower, hotter regions, resulting in a bold, more intense bitterness with higher caffeine content. He also draws attention to rarer types like Geisha, celebrated for its delicate tea-like quality and brightness, and Liberica, which presents a distinctly woody, smoky finish.
Decoding Roasting Profiles
The roasting process has a major effect on the profile and intensity of coffee. Light roasts are characterized by their light brown color and retain the original flavors of the bean, often delivering vibrant and delicate notes. Medium roasts balance bright and rich tones, featuring notes of nuts, brown sugar, and smoothness. Dark roasts, with their deeply roasted appearance 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 density differences change how strong the brew feels depending on measurement.
Crafting the Perfect Roast
Roasting transforms green coffee beans into the fragrant, flavorful grounds. Krutin breaks down the journey of roasting, starting with drying, where moisture is slowly drawn out. This is followed by the Maillard reaction, where complex molecules create aroma and color, developing the bean's color and aroma. The process includes the "first crack", signaling the development of classic coffee flavors, and can proceed to a "second crack" for intensely roasted results. He compares roasting styles, including traditional drum roasting and modern convection roasting, noting the critical role of timing and heat to minimize bitterness or burning.
Brewing Insights and Common Misconceptions
Addressing common questions, Krutin explains that putting a lid on freshly brewed coffee can trap volatile compounds, potentially distorting the profile. He also notes that while they originate from the same species, the difference is rooted in the way they’re roasted and ground, with espresso beans usually more intensely roasted and ground finer.
