What Exactly Is A Roasting Profile?

Updated: Dec 15, 2023

Roast Profile Bases


A coffee's roast profile refers to how a coffee roaster roasts a particular coffee. This usually involves deciding on the temperature, duration and other techniques used during the roasting process to achieve a specific flavor profile in the final coffee.


The roast profile has a big impact on the taste and overall quality of the coffee. So different roasters often have unique roast profiles for their coffees. A coffee roasting profile curve is a graph that shows the changes in temperature and other variables during the coffee roasting process. This can be a useful tool for coffee roasters to understand and analyze their roast profile. They also use it as needed to achieve the desired results.


A roast profile curve usually shows temperature changes over time and other important variables. These include the rate of rise or the time when certain key events, such as the first or second crack, occur. By examining the roast profile curve, roasters can better understand how their roasting techniques affect the coffee and adjust them as needed. TL;DR: A roast profile helps the roaster decide and control the taste of their coffee.

Light roast versus dark roast


Brewing, Fresh, Roasted, Coffee, Beans, Brewing, Brewing, Cash, In The two basic roast profiles you've probably heard of are light roast and dark roast. Light roast and dark roast are terms used to describe the degree of roasting of coffee beans.


Light roast coffee is roasted for a shorter time at a lower temperature, resulting in a lighter color and a more delicate flavor with a lighter acidity. Dark roast coffee, on the other hand, is roasted longer at a higher temperature, resulting in a darker color and fuller body with a stronger, stronger flavor.


The degree of roasting can have a big effect on the taste of the coffee. Because of this, roasters often use different roast levels to emphasize the unique characteristics of the coffee beans they use. Specialty coffee roasters create special and unique roast profiles for each coffee on their menu.


Effect of Roasting on taste


One question you may be asking yourself right now is "does roasting change the taste of coffee?" The roasting profile of the beans has a significant effect on the taste of the final coffee.


The roasting process causes a number of chemical changes in the beans, all of which change the final taste of the coffee. For example, the sugars in the beans caramelize, adding sweetness and complexity to the flavor.


This is called the Maillard reaction. This is the same process as caramelizing onions. The roasting process also causes the beans to expand and release more oils and flavors locked within the beans. The longer the beans are roasted, the stronger and stronger the flavor. For example, a light roast can emphasize the bright and acidic flavors of coffee, while a dark roast can emphasize chocolate or nutty flavors.


Finally, the taste of coffee depends on several factors, such as the type of beans used, the degree of roasting and the method of preparation.
