Winery Laboratories analyze and measure several important wine components, and generally use methods and equipment that have been adapted for their in-house use from common textbooks and suppliers. Few, if any, methods are rigorously standardized across the industry.  This presentation will address how a laboratory can determine and understand the analytical method performance parameters (such as accuracy and precision),  and, just as importantly, we will discuss why it would matter to track and measure these parameters.
