COFFEE GRADING

What is the 'NY Prep' standard?

Quick answer

The 'NY Prep' (New York Preparation) standard is a historical and commercial grading term used in the coffee trade to describe a specific level of quality for green coffee. It generally refers to a coffee that has been cleaned and sorted to a standard acceptable for trading on the New York Coffee Exchange, ensuring a baseline of consistency for large-scale commercial buyers.

The real story

In the global coffee trade, the 'NY Prep' standard serves as a common language for buyers and sellers who deal in large volumes of coffee. Historically, the New York Coffee Exchange (now part of the Intercontinental Exchange) required that coffee traded on its platform meet specific physical criteria to ensure that the product was uniform and free from excessive defects. This 'New York Preparation' became a shorthand for a reliable, commercial-grade coffee.

Unlike the rigorous, sensory-focused grading used for specialty coffee, NY Prep is primarily concerned with physical cleanliness. It ensures that the coffee has been properly hulled, cleaned of foreign objects like stones or sticks, and sorted to remove the most egregious defects. It is the 'standard' that allows a trader in New York to buy a container of coffee from a producer in Brazil or Vietnam without having to worry about the coffee being filled with debris or damaged beans.

For the specialty coffee industry, NY Prep is often seen as a baseline rather than a goal. While it guarantees that the coffee is 'tradeable,' it does not necessarily guarantee that the coffee will be exceptional. Specialty coffee standards, such as those set by the Specialty Coffee Association, are much stricter, requiring fewer defects and often incorporating a sensory 'cupping' score to ensure that the coffee actually tastes good.

However, the existence of the NY Prep standard is vital for the global coffee economy. It provides a safety net for the market, ensuring that there is a consistent supply of coffee that meets basic quality requirements. Without these standardized preparations, the global trade of coffee would be far more chaotic, with buyers and sellers struggling to agree on what constitutes a 'fair' product.

In practice, if you are buying coffee from a specialty roaster, you are likely getting coffee that far exceeds the NY Prep standard. Specialty roasters look for 'Specialty Grade' coffee, which is sorted much more carefully than the commercial NY Prep standard. Understanding this distinction helps you appreciate the extra effort that goes into the high-quality beans you enjoy, as they have been held to a much higher bar than the basic requirements of the global commodity market.
