SCA grading of coffee beans

What does SCA Grade 90+ mean?

A professional review of what an SCA score above 90 practically signifies: how it's determined, what it measures, and important limitations to be aware of.

What does SCA Grade 90+ mean?

Brief summary

SCA Grade 90+ means that a coffee has been rated 90 points or more on the Specialty Coffee Association's 100-point scale. The score comes from a structured sensory evaluation (cupping) according to standardized criteria.

It's important to understand that a score is primarily a technical language for quality in a tasting situation. It says a lot about cleanliness, balance, and overall execution — but it's not a guarantee that a specific flavor profile will suit everyone.

How does the SCA scoring system work?

The SCA scoring system is based on tasters evaluating a number of defined characteristics and combining them into a total score. During cupping, the following are typically evaluated:

  • Aroma/fragrance
  • Flavor and aftertaste
  • Sweetness
  • Acidity (quality and structure)
  • Body/mouthfeel
  • Balance
  • Clean cup
  • Overall impression

In-depth: what "standardized" means (and doesn't mean)
Standardization means using the same basic framework (setup, forms, and evaluation points). It doesn't eliminate human variation, but it makes results more comparable between different actors and over time.

What distinguishes coffee that reaches 90+?

To reach 90+, several parts of the chain often need to be of high quality simultaneously. It's rarely about a single factor, but about combined precision: harvesting, processing, drying, sorting, and raw material quality.

Practically recurring

Very low defect rate in green coffee, controlled processing (e.g., fermentation/drying), and a profile that yields high clarity, balance, and distinct sensory attributes in cupping.

In-depth: why defects play such a big role
Defects (e.g., damage, incorrect drying, over-fermentation) often lead to disturbing, recurring flavors that lower "clean cup," balance, and overall impression. At a high score level, the margins become small.

How does coffee scoring over 90 points taste?

90+ does not describe a particular style, but how strongly the coffee performs within criteria such as cleanliness, balance, structure, and complexity. Therefore, two 90+ coffees can taste completely different, even if both are judged to be technically very well-executed.

Important to distinguish Preference (what you like) and quality according to protocol (what is judged as well-executed in cupping) are related, but not the same thing.

Example: common quality traits often clearly felt in 90+
Many 90+ coffees are perceived as "transparent": easy to distinguish aromas, clean aftertaste, and a structure where acidity, sweetness, and body connect without sharp edges. Exact aroma associations, however, vary greatly.

Q-Grader – who sets the score?

A Q-Grader is a certified coffee grader trained and examined to evaluate coffee according to internationally standardized sensory protocols. The certification is closely linked to the cupping methods used in specialty coffee and is managed by organizations such as :contentReference[oaicite:0]{index=0}. The Q-Grader's role is not to decide what is ”good”, but to consistently and reproducibly describe quality according to a common framework.

What the certification means in practice

To become a Q-Grader, one must pass a comprehensive number of practical and theoretical tests, including triangulation (identifying deviant cups), recognizing aromas and defects, evaluating acidity and balance, and correctly using cupping forms. The certification is time-limited and must be regularly renewed, meaning that sensory precision is continuously tested.

In Sweden, Q-Graders often work in several roles simultaneously. It is common for the same person to be responsible for purchasing, internal quality assurance, and training at a roastery, or combining work as a consultant and grader. Cupping therefore rarely occurs in isolation. Instead, coffee is often tasted in groups, where several graders calibrate their impressions, compare scores, and discuss descriptions to ensure consistency.

How Q-Graders are used in everyday Swedish practice
In practice, this means that scoring in Sweden is often a collective effort. A coffee may be tasted multiple times, in different contexts and sometimes by different Q-Graders, before a score is considered stable. The Q-Grader certification then functions as a common language and a methodical foundation, rather than as an individual definitive answer.

Limitations and common misconceptions

Sensory evaluation is robust, but never completely "objective". It's good to be aware of limitations when scores are used as an indicator.

Three things to remember

(1) The score is affected by the tasting setup and calibration between tasters. (2) Preference is personal. (3) The score is a composite — it doesn't always explain why a coffee is perceived strongly.

Historical context image related to coffee production
Context and history Coffee grading as an idea is relatively young. For most of the 20th century, coffee was primarily classified based on trade standards, physical defects, and appellations of origin, rather than how the coffee actually tasted in the cup. It was only later in the century, with the emergence of specialty coffee, that sensory quality began to be formalized and systematically documented. The work of creating common cupping protocols and a score-based language culminated in the frameworks used and maintained today by organizations such as the Specialty Coffee Association. Grading thus became a tool for communication and comparability between producers, exporters, roasters, and tasters – rather than an absolute measure of "good" or "bad." Understanding this historical context is important: the scoring system is an attempt to create structure in a fundamentally sensory and human field, not to replace judgment or personal taste.
