White Labs offers third party analytical testing that is independent of the White Labs internal yeast production laboratory. Tests are conducted using the strictest standards employing methods prescribed by the American Society of Brewing Chemists and AOAC. Many countries require TTB certified lab documentation for export of alcohol products and White Labs has several certified TTB beer chemists on staff. The lab participates in quarterly check sample service to assess accuracy and quality control within the lab which allows White Labs to be confident in the data we are providing our customers. White Labs conducts tests and delivers results in a prompt manner, providing customers with information that is both timely and accurate.
