6% acidity There are no shortcuts to making handcrafted vinegar. The release of our new KATZ Pinot Noir Vinegar, Napa Valley, represents our first “Single Vineyard” designation. These are very limited lots of grapes that are all grown in one provenance highlighting a single varietal. This vinegar comes from 100% Pinot Noir grapes harvested from the world-renowned Oak Knoll region in the heart of the Napa Valley. I was fortunate to strike up a friendship with a highly respected winemaker from the area, and I mentioned to him that if he ever had some small production wine that he could part with, I would like to try converting it to vinegar and maintaining the integrity of the varietal.
