The following is a brief introduction to the topic:
There’s more than just aroma and taste to the coffee experience website. Coffee beans’ appearance, whether raw or roasted, is an important aspect of the coffee industry that is often overlooked. The Agtron Scale has revolutionized coffee by standardizing and quantifying the color of the beverage. It helps coffee producers, roasters and consumers understand this aspect of their favorite beverage that is often overlooked.
Understanding the Agtron Scale
Agtron Scale (short for Agriculturaltron) was developed in the 1960s by the Agtron Corporation. It was originally designed to measure the colour of agricultural products. However, the coffee industry found it most useful. This scale assigns a numerical value for the color of the coffee, allowing coffee professionals to communicate more easily and achieve consistency during the roasting process.
Coffee Color: It’s Important
The coffee bean’s color is the result of caramelization and Maillard reaction that occur during roasting. The color of coffee beans is a direct reflection of the roasting level, and it can have a significant impact on the flavor profile. The different roast levels from light to darker bring out distinct flavors and characteristics of the coffee.
Light Roasts: These beans are typically higher in Agtron (e.g. 75-95), and have floral and fruity notes that are prominent.
Medium Roasts: These roasts fall in the middle (e.g. 50-70), and offer a balanced taste profile that highlights both the bean’s origin as well as the roasting method.
Dark Roasts: Dark-roasted beans are characterized by a lower Agtron number (e.g. 25-45), and their bittersweet, bold and smoky flavors make them a favorite.
The Agtron Scale has many benefits
The Agtron Scale offers several benefits to the coffee sector:
a. Consistency: The Agtron Scale allows coffee professionals to accurately communicate and reproduce roast levels, ensuring consistent quality.
b. Quality Control: Roasters monitor the color and intensity of the beans as they roast them to avoid over- or under-roasting which can alter the flavor and aroma.
c. Consumer choice: Coffee lovers are able to use Agtron numbers in order to select beans that match their desired roast level and flavor profile.
Fair Trade and Quality Assessment – In the coffee industry, Agtron scores are used to assess the value and quality of the beans. This helps with fair pricing and the assessment of quality.
