What is the 'Preparation' (EP/AP) standard?

In the world of green coffee trading, 'Preparation' refers to the level of sorting and defect removal a lot has undergone before export. These terms, most notably European Preparation (EP) and American Preparation (AP), serve as a shorthand for buyers to understand the physical quality of the coffee without having to inspect every single bag. They are essentially quality control benchmarks that define how much effort was put into cleaning the coffee.

European Preparation (EP) is widely considered the more rigorous of the two. Historically, this standard was developed to meet the high expectations of European specialty markets. An EP-graded coffee typically requires that the beans be sorted to a specific screen size (often 15 or higher) and that the number of primary and secondary defects is kept to a very low threshold. It is a mark of consistency and care, signaling to the buyer that the coffee has been meticulously processed.

American Preparation (AP), by contrast, is often more flexible. While it still involves sorting, the standards for defect counts and screen size uniformity are generally less stringent than those for EP. This does not necessarily mean the coffee is of poor quality; rather, it reflects a different market demand where price and volume might be prioritized alongside quality. AP coffee is often used in blends or for markets where the specific, high-uniformity requirements of EP are not required.

In practice, these standards help streamline the global coffee trade. When a trader lists a coffee as 'EP,' the buyer knows exactly what to expect regarding the physical appearance and defect count of the beans. It reduces the need for extensive back-and-forth communication about quality. However, it is important to remember that these are physical standards. They do not guarantee the flavor profile of the coffee, which is why physical grading is always paired with sensory cupping to determine the final value of the lot.
