Big QC Day

Big QC Day began in 2007 as a way to provide a low-cost option for breweries to get a variety of tests conducted. Each year, at least 10 percent of the country's craft breweries participate. Big QC Day kits test for diacetyl and IBUs, as well as alcohol, calories, color, real and apparent attenuation, microbiological contaminants, and more. Test two samples for $139 or $199 for two samples plus gluten testing.
