Big QC Day

White Labs® offers year-round analytical testing for your fermented beverages. We began Big QC Day in 2007 as a way of providing a low-cost option for breweries wishing to have multiple analytical tests conducted at once. It has become a program where professional brewers are able to take advantage of big savings. In total, at least 10 percent of the country's craft breweries participate in Big QC Day throughout the year.

Purchase a test kit, send in your samples and we'll test it for the following:

  • Diacetyl
  • IBUs
  • Alcohol content 
  • Calories
  • Color (SRM)
  • Attenuation - real and apparent
  • Microbiological contaminants
  • ...and more! 

The cost for testing two samples is $139 or $199 for two samples with gluten testing.
