Before Deciding Whether a Coffee Is “Good,” We First Need to Describe What We Actually Perceive

When we say a coffee is “good,” what do we really mean? Is it the aroma, the taste, the texture, or something else? Before making any judgment about quality or preference, we need to understand what we actually perceive when tasting coffee. This is the foundation of the Specialty Coffee Association’s (SCA) Coffee Value Assessment, which separates descriptive sensory attributes from quality judgment and personal preference.

In this post, I will walk you through how descriptive assessment works, focusing on sensory attributes and their intensity. We will explore key tools like intensity scales, Check-All-That-Apply (CATA) methods, flavor notes, blind coding, and the five grouped sections of the descriptive form. Along the way, I will share examples and practical tips to help you better understand and appreciate coffee. Let’s dive in.

Understanding Descriptive Assessment in Coffee

Descriptive assessment is a method used to record what we sense in coffee without mixing it with our personal likes or dislikes. It focuses on identifying specific sensory attributes and measuring their intensity. This approach helps separate objective description from subjective judgment.

For example, instead of saying “I like this coffee,” descriptive assessment asks:

• How strong is the acidity?

• What kind of aroma does it have?

• Is the body light or heavy?

• Are there any specific flavor notes like chocolate, citrus, or floral?

  
  

This method allows roasters, producers, and consumers to communicate clearly about coffee characteristics. It also helps improve coffee quality by pinpointing what works and what doesn’t.

Intensity Scales and How They Work

One of the key tools in descriptive assessment is the intensity scale. This scale measures how strong or weak a particular sensory attribute is in the coffee. Usually, it ranges from 0 (none) to 10 (very strong).

For example, when assessing acidity, you might rate it as 7 if the coffee has a bright, sharp acidity, or 2 if it is very mild. This numeric value helps compare coffees objectively.

Using intensity scales requires training and practice. You need to learn how to recognize each attribute and calibrate your perception. Over time, you develop a more precise palate.

Check-All-That-Apply (CATA) Method

The CATA method is a simple but effective way to describe coffee. Instead of rating intensity, you check all the sensory attributes that apply to the coffee you taste.

For example, a CATA list might include:

• Fruity

• Nutty

• Floral

• Earthy

• Spicy

• Sweet

  
  

You check all that you detect. This method is fast and useful for quick profiling or consumer testing. It also helps identify common flavor notes across different coffees.

Flavor Notes and Their Importance

Flavor notes are the specific tastes and aromas you detect in coffee. They can range from fruits like berries and citrus to spices, nuts, chocolate, and even floral hints.

Describing flavor notes accurately is essential for understanding coffee’s complexity. It also helps producers highlight unique qualities of their beans.

For example, iO Coffee Vietnam offers a specialty coffee that features bright citrus acidity with hints of jasmine and honey. Knowing these notes helps consumers appreciate the coffee’s profile and origin.

Blind Coding and Its Role in Objective Tasting

Blind coding means tasting coffee samples without knowing their identity. This removes bias and helps tasters focus purely on sensory attributes.

In professional cuppings, coffees are coded with numbers or letters. Tasters record their observations without influence from brand, origin, or price.

Blind coding improves the reliability of descriptive assessment. It ensures that judgments are based on what is actually perceived, not on expectations or preferences.

The Five Grouped Sections of the Descriptive Form

The SCA’s descriptive form organizes sensory attributes into five main sections. Each section covers a different aspect of coffee’s sensory profile:

1. Aroma

   This includes the smell of dry grounds and brewed coffee. Common descriptors are floral, fruity, nutty, and earthy.

   
   

2. Flavor

   This covers the taste and aroma combined. It includes sweetness, acidity, bitterness, and specific flavor notes.

   
   

3. Aftertaste

   The lingering taste after swallowing. It can be pleasant or unpleasant, short or long.

   
   

4. Acidity

   The sharpness or brightness in coffee. It can be citrusy, malic (apple-like), or lactic (milk-like).

   
   

5. Body

   The weight or thickness of coffee in the mouth. It ranges from light to full.

   
   

Each section is rated for intensity and described with specific terms. This detailed breakdown helps create a full sensory profile.

Practical Example: Comparing Two Specialty Coffees

Let’s compare two specialty coffees using descriptive assessment:

• Coffee A: Bright acidity (7), floral aroma, medium body, sweet with notes of honey and jasmine.

• Coffee B: Low acidity (3), nutty aroma, full body, chocolate and caramel notes.

  
  

Both coffees can be “good,” but they offer different experiences. Descriptive assessment helps us understand these differences clearly.

Why Descriptive Assessment Matters for Coffee Lovers and Producers

Descriptive assessment benefits everyone in the coffee chain. For producers, it helps improve bean quality and market value. For roasters, it guides roasting profiles to highlight the best attributes. For consumers, it enhances appreciation and informed choices.

iO Coffee Vietnam aims to change the global coffee industry by helping producing countries, especially Vietnam, add value to their coffee beans. Using descriptive assessment tools supports this mission by promoting transparency and quality.

How to Start Using Descriptive Assessment at Home

You don’t need to be a professional to start describing coffee better. Here are some tips:

• Use a simple flavor wheel or CATA list to identify notes.

• Practice rating intensity on a 0-10 scale for acidity, bitterness, and body.

• Taste coffee blind if possible, without knowing the brand or roast.

• Take notes on aroma, flavor, aftertaste, acidity, and body.

• Compare different coffees side by side.

  
  

This practice sharpens your palate and makes coffee drinking more enjoyable.

Describing what we perceive in coffee is the first step before deciding if it is “good.” The SCA’s Coffee Value Assessment provides a clear, structured way to do this. By focusing on sensory attributes and their intensity, we can communicate more clearly and appreciate coffee’s complexity.

If you want to explore specialty coffee with clear sensory profiles, consider trying products like those from iO Coffee Vietnam. Their commitment to quality and sustainability brings unique Vietnamese coffee flavors to the world.
