ROASTING

What is a "Sample Roast"?

Quick answer

A "Sample Roast" is a small-batch roasting process used by coffee professionals to evaluate the quality and potential of green coffee before buying or selling it. By roasting a small, standardized amount—usually 100 grams—roasters can perform a cupping session to identify defects, determine the roast profile, and ensure the coffee meets quality control standards.

The real story

Before a roaster commits to buying several tons of green coffee, they need to know what they are getting. A sample roast is the tool of choice for this "due diligence." It is not about creating the perfect retail-ready roast, but rather about bringing the coffee to a neutral, repeatable roast level so it can be evaluated objectively. This allows the buyer to taste the intrinsic characteristics of the bean rather than the influence of the roaster's specific style.

During a sample roast, the roaster follows a very precise, standardized protocol. The beans are typically roasted to a light-to-medium degree, which is optimal for highlighting both the good qualities—like sweetness and acidity—and the bad qualities, such as fermentation defects, mold, or "tardy" flavors. After roasting, the coffee is ground and prepared for a process called cupping.

Cupping is a formalized tasting method where the coffee is brewed in a standardized way—just grounds and hot water in a bowl—to remove all other variables. This is the ultimate test of the coffee's quality control. If the sample roast reveals inconsistencies or defects, the roaster will pass on the lot. If it scores well, they move forward with negotiations.

For the average coffee drinker, you won't encounter a "sample roast" on the shelf. However, understanding this process gives you insight into why the specialty coffee industry is so obsessed with quality. Every single coffee you enjoy from a high-quality roaster has gone through this rigorous vetting process. It ensures that the coffee hasn't just been roasted well—it has been carefully selected and verified to ensure it is of the highest possible grade.
