Coffee is one of the most beloved beverages in the world, enjoyed by millions of people every day. However, not all coffee is created equal. There are different grades of coffee, each with distinct characteristics, flavors, and price points. In this blog post, we'll explore the various grades of coffee, what sets them apart, and why higher grades are more sought after and expensive.

The Basics of Coffee Grading

Coffee grading is a system used to evaluate the quality of coffee beans. This system considers several factors, including bean size, shape, color, and defects, as well as the flavor profile of the brewed coffee. Coffee is typically graded by professional coffee tasters, known as cuppers, who assess these factors through a process called cupping.

There are several grading systems used worldwide, but two of the most common are:

  1. Specialty Coffee Association (SCA) Grading: This system rates coffee on a 100-point scale. Coffees scoring 80 points or above are considered specialty grade.
  2. Green Coffee Classification: This system, used by the Coffee Quality Institute (CQI), categorizes coffee beans based on size, defects, and processing methods.

Different Grades of Coffee

  1. Specialty Grade Coffee

    Specialty grade coffee is the highest quality coffee available. It is meticulously grown, harvested, and processed to ensure the best possible flavor. To be classified as specialty grade, coffee must score 80 points or higher on the SCA scale. This grade has few, if any, defects and offers a unique and desirable flavor profile.

    Characteristics of Specialty Grade Coffee:

    • Handpicked to ensure only the ripest cherries are selected.
    • Minimal defects (no more than 5 defects in 300 grams of beans).
    • Complex flavor profiles with distinct notes and aromas.
    • Often single-origin, meaning the beans come from a specific region or farm, not blended from multiple sources.
  2. Premium Grade Coffee

    Premium grade coffee is of high quality but does not meet the stringent standards of specialty grade. It typically scores between 70 and 80 points on the SCA scale. While it may have some defects, they are minor and do not significantly impact the flavor.

    Characteristics of Premium Grade Coffee:

    • Generally handpicked, but may include some machine harvesting.
    • Slightly higher defect count than specialty grade.
    • Good flavor, though less complex than specialty grade.
    • Often used in premium blends.
  3. Exchange Grade Coffee

    Exchange grade coffee is mid-grade coffee, scoring between 60 and 70 points on the SCA scale. It is commonly used in commercial coffee blends. This grade allows for more defects and may include a mix of different bean sizes and shapes.

    Characteristics of Exchange Grade Coffee:

    • Often machine harvested.
    • Noticeable defects but still drinkable.
    • Basic flavor profile, suitable for everyday consumption.
    • Commonly found in grocery stores and coffee chains.
  4. Standard Grade Coffee

    Standard grade coffee is lower quality coffee, typically scoring below 60 points on the SCA scale. This grade includes a higher number of defects and lacks the distinct flavors of higher-grade coffees. It is often used in instant coffee and low-cost blends.

    Characteristics of Standard Grade Coffee:

    • Mostly machine harvested.
    • Higher defect count.
    • Simple, often bitter flavor profile.
    • Used in mass-market products.
  5. Off-Grade Coffee

    Off-grade coffee is the lowest quality coffee, with numerous defects and poor flavor. It is often considered unsuitable for direct consumption and may be used for industrial purposes or as filler in very low-cost coffee products.

    Characteristics of Off-Grade Coffee:

    • High defect count.
    • Poor flavor, often harsh or unpleasant.
    • Not typically sold for direct consumption.

Why Higher Grades of Coffee Are More Sought After

Higher grades of coffee are more sought after for several reasons:

  1. Flavor and Aroma: Specialty grade coffees offer complex and unique flavor profiles that are highly prized by coffee enthusiasts. These coffees can have notes of fruit, chocolate, spices, and more, providing a rich and enjoyable drinking experience.

  2. Freshness and Quality: Higher-grade coffees are often fresher and of higher quality because they are carefully harvested and processed. Specialty coffees, in particular, are usually roasted in small batches to ensure optimal freshness as well as evenly evoking the desired flavor profile.

  3. Traceability and Sustainability: Specialty grade coffees often come with detailed information about their origin, including the farm, region, and even the specific lot. This traceability allows consumers to make informed choices and support sustainable and ethical farming practices.

  4. Limited Supply: High-quality coffee beans are often produced in limited quantities due to the meticulous care required in their cultivation and processing. This limited supply makes them more exclusive and desirable.

  5. Health Benefits: Higher-grade coffees are less likely to contain defects and contaminants, making them a healthier choice. Additionally, they often have higher levels of beneficial compounds, such as antioxidants.

Why Higher Grades of Coffee Are More Expensive

The higher cost of specialty and premium grade coffees can be attributed to several factors:

  1. Labor-Intensive Harvesting and Processing: Specialty grade coffee requires handpicking, careful sorting, and precise processing methods, all of which are labor-intensive and time-consuming. This meticulous care ensures the highest quality but also increases the cost.

  2. Quality Control: To maintain high standards, specialty coffee producers invest in rigorous quality control measures, including cupping sessions, defect removal, and proper storage. These measures add to the overall cost of production.

  3. Limited Production: As mentioned earlier, high-quality coffee beans are produced in limited quantities. The scarcity of these beans drives up their market value.

  4. Sustainable Practices: Many specialty coffee producers adhere to sustainable and ethical farming practices, such as organic farming, fair trade certification, and environmental conservation efforts. These practices often involve higher costs but result in better quality and more environmentally friendly products.

  5. Roasting and Packaging: Specialty coffee is often roasted in small batches to ensure freshness and preserve flavor. This small-batch roasting, along with high-quality packaging materials, adds to the overall cost.

  6. Marketing and Branding: Specialty coffee brands invest in marketing and branding to differentiate their products and convey their unique qualities. This investment in branding helps justify the higher price point.


Understanding the different grades of coffee and their distinct characteristics can enhance your appreciation for this beloved beverage. While higher grades of coffee come with a higher price tag, the superior flavor, quality, and ethical considerations make them worth the investment for many coffee lovers. Whether you're a casual coffee drinker or a dedicated aficionado, exploring the world of specialty and premium grade coffees can provide a richer and more enjoyable coffee experience.
