Coffee Bean Grading: Understanding Quality Standards

collaborative post | The world of coffee is rich and diverse, with an array of flavours and characteristics to explore. But how can you tell if you’re getting the best-quality beans? Understanding coffee bean grading is the key to unlocking the secrets behind that perfect cup of coffee. 

Let’s talk about the fascinating world of coffee bean grading and the quality standards that distinguish exceptional coffee beans from the rest.

The Basics of Coffee Bean Grading

What makes coffee beans different?

Coffee beans are graded based on several factors, including their size, shape, density and visual defects. These factors collectively contribute to the overall quality and flavour profile of the coffee. Here’s a closer look at the key elements of coffee bean grading:

1. Bean size – Coffee beans are sorted by size, typically into categories like ‘screen size.’ Larger beans are often associated with better quality and flavour due to their more even roasting characteristics.
2. Bean shape – The shape of the coffee beans can vary, with some beans being more oval, round or peaberry-shaped. Peaberries, in particular, are known for their unique flavour profiles.
3. Density – The density of coffee beans affects how they roast and brew. Denser beans tend to roast more evenly and often produce a better cup of coffee.
4. Visual defects – Coffee beans are carefully inspected for visual defects, such as insect damage, mould or discolouration. Beans with defects are often sorted out during the grading process.

Understanding Coffee Bean Grading Scales

The importance of grading scales

Coffee beans are typically graded on a numerical scale, with different regions and organisations using their own systems. There are also widely recognised grading scales that assess various aspects of coffee bean quality, including flavour, aroma, acidity, body and balance. One example is the Specialty Coffee Association (SCA) Scale.

Specialty Coffee Association (SCA) Scale:

The SCA scale, also known as the ‘Coffee Quality Institute’ scale, uses a 0 to 100-point system. It evaluates factors like fragrance/aroma, flavour, aftertaste, acidity, body, balance, uniformity and clean cup.

Understanding coffee bean grading can help you make informed choices when selecting coffee beans. Look for beans with higher grades on reputable grading scales to ensure a better coffee experience. Keep in mind that different regions and growing conditions can also influence coffee flavour, so don’t hesitate to explore various origins and varieties.
