Whereas roast coloration in specialty espresso is taken into account an necessary parameter (i.e., mild, medium, darkish, and many others.), a brand new strategy makes use of coloration considerably otherwise—as a basic quality-control instrument. We talked to Morten Münchow, founding father of CoffeeMind, to get his insights on the position of coloration in espresso roasting, and easy methods to strategy roasting espresso in a easy, tailor-made approach to match a enterprise.

The Position of Colour in Espresso Roasting

With an instructional background in biology and philosophy, in addition to years of expertise within the espresso trade as a roaster, marketing consultant, and coach, Morten has a large perspective on espresso.

They printed their findings in an article titled “Roasting Circumstances and Espresso Taste: A Multi-Research Empirical Investigation.”

”Our intention is to supply a sensible framework for the espresso trade to grasp how roast coloration and time impacts taste. Our analysis has discovered that coloration is a very powerful issue to contemplate in product growth and quality-control procedures for roasted espresso. Time after first crack can also be a major issue, however elements comparable to fee of rise (roast curve) fall decrease within the order of precedence in product growth and high quality management procedures,” Morten explains. This would possibly sound stunning to some, as there’s not a lot speak about coloration in the case of espresso roasting—the main focus is often on time, temperature, and roast curves.

To assist additional, they created a coloration palette that permits espresso roasters to check and doc the colours of various coffees. The central reference coloration is surrounded by compartments the place samples might be added throughout roasting. Because the beans are roasted, they develop into darker and ultimately match the central coloration. Developed for coaching and analysis functions, this palette is a great tool for espresso roasters to have a extra goal strategy of their decision-making processes in the case of roast profiles.

If we take a simplified and systematic strategy to espresso roasting, we will serve the espresso group with higher high quality, consistency and, above all, confidence,” he says.
