A Pennsylvania brewer has partnered with a molecular diagnostics company to develop a rapid assay to detect beer-spoiling bacteria. Invisible Sentinel and Victory Brewing will develop an assay based on Invisible's Veriflow technology to detect Pediococcus and Lactobacillus, which produce lactic acid and affect beer taste. The partners said that current methods of detecting the bacteria are laborious and time-consuming and can delay the implementation of corrective measures. In turn, that can result in brew spoilage, higher production costs and delayed product release.
