Big QC Day

Quality is a term used almost every day in the brewing industry and it encompasses many aspects of brewing, from ingredients to process to packaged beer. For the last 25 years at White Labs, we set out on a single mission: to stretch the limits of science to set new standards and support quality in every aspect of beer.

As part of this mission, we launched Big QC Day in 2007 as a low-cost option to help breweries understand the quality of their beer. It also lets participants compare their samples to others and gain insight into the ever-evolving industry. In 2019, we learned that the craft brewing industry has an average ABV of 6.29%, IBU of 34, and diacetyl of 43.49 ppb. In addition, we found that of the 730 samples we tested, 39.76% were using STA+ strains.
