Are there grading standards for cold brew coffee?

While the specialty coffee industry has rigorous, globally recognized standards for grading green coffee—such as the SCA defect classification and cupping protocols—these standards do not extend to the final cold brew product. Cold brew is a method of extraction, not a specific bean variety or processing style, which makes creating a universal 'grade' for the liquid product exceptionally difficult.

In practice, the quality of cold brew is determined by the quality of the input material and the precision of the brewing process. Roasters and cafes typically use high-quality, specialty-grade beans to ensure a clean, sweet, and complex cup. Because cold brew is a long-contact, low-temperature extraction, it highlights different flavor compounds than hot brewing. Defects that might be masked in a hot cup can sometimes become more pronounced or altered in a cold brew, making the selection of the green coffee even more critical.

Instead of a formal 'grade,' professionals in the cold brew space rely on technical metrics to ensure consistency. These include measuring Total Dissolved Solids (TDS) to determine the strength of the concentrate and calculating extraction yield to ensure the coffee is not under- or over-extracted. Sensory evaluation remains the gold standard, where experts cup the cold brew to check for clarity, acidity, and the absence of off-flavors like 'tarry' or 'fermented' notes.

For the consumer, this means that 'cold brew' is not a regulated term. A bottle labeled as cold brew could be made from high-end, single-origin beans or low-grade commercial coffee. Without a formal grading standard, the best indicator of quality remains the transparency of the roaster, the freshness of the roast, and the specific brewing parameters used. As the market matures, we may see more standardized sensory language, but for now, quality is defined by the roaster's own internal benchmarks.
