India is renowned for its unique coffee grading system, which is primarily based on the processing method and the size of the beans. The country uses both wet (washed) and dry (natural or unwashed) methods to process coffee, leading to distinctive nomenclature and grading classifications.
Wet-Processed Coffee
In India, wet-processed (washed) Arabica beans are referred to as “Plantation” coffee. This is not to be confused with coffee estates, which are also commonly called plantations. The term “Plantation” in this context specifically refers to the washing process that Arabica beans undergo. For Robusta beans, the equivalent term is “Parchment,” reflecting the same wet-processing method.
Arabica Grades (Washed):
- Mysore Nuggets Extra Bold: Considered the highest grade, known for its large, uniform beans with minimal imperfections.
- Plantation-AA: A high-grade Arabica, characterized by large beans with a higher density and more refined flavor profile.
- Plantation-PB Bold and Plantation-PB: These grades refer to peaberry beans, which are smaller and rounder due to a natural mutation.
- Plantation-A, B, C, BBB, Bulk: These represent decreasing sizes and qualities, with lower grades allowing for more imperfections.
Robusta Grades (Washed):
- Robusta Kaapi Royale: The top-tier grade for washed Robusta, known for its bold, full-bodied flavor.
- Parchment-A, PB Bold, PB, AB, B, C, BBB, Bulk: Similar to Arabica, these grades represent the quality and size of Robusta beans, with the grading system primarily focusing on bean size and the allowance for imperfections.
Dry-Processed Coffee
In the dry-processing method, both Arabica and Robusta beans are collectively known as “Cherry.” This name should not be confused with the actual cherry fruit on a coffee tree. The “Cherry” designation indicates that the beans were dried with the fruit still attached, leading to a different flavor profile compared to washed beans.
Arabica Grades (Natural/Dry-Processed):
- Cherry-AA: The highest grade, with large, well-dried beans that have a robust flavor.
- Cherry-A, PB Bold, PB, AB, C, BBB, Bulk: These grades decrease in size and quality, with lower grades having more imperfections.
Robusta Grades (Natural/Dry-Processed):
- Cherry-AA: The top grade for natural Robusta, offering a strong, intense flavor.
- Cherry-A, PB Bold, PB, AB, C, BBB, Bulk: These follow the same grading principles as the Arabica Cherry grades, focusing on size and the presence of imperfections.
The Significance of Bean Size and Quality
The grading system in India is largely based on the size of the coffee beans, determined by the sieves they pass through during processing. Larger beans are generally considered superior as they often indicate better development and quality. The highest grades, such as Mysore Nuggets Extra Bold for Arabica or Robusta Kaapi Royale, also impose strict limits on the percentage of imperfections allowed, ensuring a premium coffee experience.
Understanding these traditional grades helps in appreciating the nuances of Indian coffee, where the combination of processing methods, bean size, and quality standards creates a diverse and rich coffee culture. Whether you prefer the bold flavors of Robusta or the refined notes of Arabica, India’s coffee grading system offers something for every palate.
