Sample Roasting Protocol

A sample roasting protocol is the industry standard for quality control. When green coffee importers or roasters receive samples from a farm, they must roast them in a way that is consistent and repeatable to ensure that the evaluation is fair. By using a specific, controlled method—often involving a small sample roaster—they can strip away the variables of production roasting and focus entirely on the inherent characteristics of the bean.

What is the goal of this protocol? It is to achieve a 'standard' roast that highlights the coffee's true nature without introducing roast-derived flavors like smoke or excessive bitterness. The protocol typically specifies the charge weight, the target drop temperature, and the total roast time. By keeping these variables constant, cuppers can compare different lots of coffee side-by-side with confidence.

This process is vital for the specialty coffee supply chain. It allows farmers to receive feedback on their processing methods and helps buyers make informed decisions about which coffees to purchase. If a coffee performs well under a standard sample roast, it is a strong indicator that it will also excel when roasted for production.

In practice, the sample roasting protocol is the first step in the journey from farm to cup. It is a rigorous, scientific approach to sensory evaluation that ensures only the highest quality coffees reach the market. For the coffee professional, it is an essential tool for maintaining standards and discovering exceptional lots that might otherwise go unnoticed.
