Use the tools below to supplement your Quality Control program.
The following material was written by OBL’s Dana Garves to assist brewers in pursuing a high quality product.
Dana Garves, founder of Oregon BrewLab, explains some of the key tools to ensure impeccable quality standards when working with a contract brewer.
Quality control a) is affordable, b) allows brewers to brew better, more consistent beer, and c) ultimately saves money. Build a Laboratory for less than $500.
Quality Assurance & Quality Control Terminology
Maintaining standards in fermented products by analyzing a sample of the beer against the expected product. Focuses on the product.
Maintenance of quality in beer by means of attention to every stage of brewing, fermentation, cellaring and packaging. Focuses on the process.
Laboratory Control Standard (LCS)
A sample whose result is known prior to analysis. This allows the chemist to verify technique and verify an instrument’s calibration.
Samples were the result is zero. Necessary to ‘zero’ the instrument for calibration.
Serve as an indicator of instrument stability, consistency in laboratory sample preparation and analysis.
Relative Percent Difference (RPD)
When using duplicate samples, determine precision by
calculating RPD. The smaller the value, the more precise the measurements.
A measure of the nearness of an analytical result to the true value.
Determines the consistency, or repeatability, of analytical measurements.
Certificate of Analysis
BrewLab strives to increase the standard of Oregon Beer quality – only the finest beers are made in the Northwest. In order to provide you with the highest quality control and assurance possible, our chemists use the same high QA/QC standards for beer analysis as you do for brewing. And we can prove it.
Request a copy of your sample’s CoA. These results are measured for every batch of 10 beers using quality standards such as Blanks, Laboratory Control Standards (LCS), Duplicates, and Relative Percent Difference (RPD).
