The Winemakers Research Exchange is a non-profit organization of Virginia winemakers pursuing quality improvement through practical experimentation in vineyards and wineries.
Experimental results are evaluated using appropriate chemical measures. Sensory sessions allow for blind tasting and group discussion of each project.
Results from past experiments are shared during sensory sessions, on the website, through newsletters, and at regional and national meetings.
Whether you are using in-house testing or sending samples to a service lab, juice chemistry values inform crucial winemaking decisions such as harvest dates, chaptalization and acidulation. How do you know if you can trust the numbers you are getting?
In 2021, Rick Tagg of Delaplane Cellars investigated this questions with a “Secret Shopper” experiment to determine precision and accuracy of juice chemistry testing for three of the service labs offering juice testing in Virginia. I met up with Rick via Zoom to discuss the results.
