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.
