​140. The role of reference standards in modern brewing chemistry

​Finishing and Stability Session

John Laferty, ERC A Waters Co, Golden, CO, USA
 
ABSTRACT: For many industries, the use of analytical reference standards has always been a valuable tool for process/product quality control, and the brewing industry is no exception. As technology in the brewing community continues to advance, the use of chemical reference standards is becoming more commonplace for routine quality control, as well as to help solve brewing anomalies impacting flavor, quality, consistency, and stability. This poster presents case studies where chemical reference materials were used to identify and quantify constituents or by-product compounds that impacted the flavor and quality of beer. The importance of using quality chemical reference standards is paramount to a brewing laboratory’s success. Chemical reference standards should be obtained from ISO 17025/ISO Guide 34 accredited suppliers.
