Can't decide what type of Sensory Panel to run?
Easy Peasy! You can download the Sensory Evaluation Flowchart created by Oregon Brewlab. Utilize this chart to determine what type of Sensory Panel fits your hypothesis best.
Quality Control & Assurance Terminology
Quality Control
Maintaining standards in fermented products by analyzing a sample of the beer against the expected product. Focuses on the product.
Quality Assurance
Maintenance of quality in beer by means of attention to every stage of brewing, hot side and cold side. Focuses on the process.
Duplicates
(DUPs)
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.
Laboratory Conrol Standard (LCS)
A sample whose result is known prior to analysis. This allows the chemist to verify technique and verify an instrument’s calibration.
Blanks
Samples were the result is zero. Necessary to tare or ‘zero’ the instrument for calibration.
Accuracy
A measure of the nearness of an analytical result to the true value.
Precision
Determines the consistency, or repeatability, of analytical measurements.

Oregon’s First Women Brewers [1879-1908]
ale·wife ♦ ˈālwīf/ ♦ noun
A female who brews beer. syn: brewster, brewess
This article is focused on detailing Oregon’s brewsters after statehood but prior to Prohibition. Utilizing various sources, I examined the state records of the breweries and any historical details I could find on women brewers. It’s time to do these ladies justice for their hard work in brewing by telling of their stories. In Oregon, these five women paved the way for us lady beer lovers before prohibition.
