Michael David Winery produces wines from California grapes, with particular focus on Petite Sirah and Zinfandel. The winery's Petite Sirah and Inkblot Petite Sirah have been assessed by Wine Enthusiast, Decanter, Wine Advocate, and Falstaff. The Rage Zinfandel rounds out the portfolio. Petite Sirah, a dark-skinned variety known for deep color and structured tannins, forms the backbone of the winery's output. Zinfandel, California's signature red, brings ripe fruit and spice. These varietals reflect the winery's commitment to bold, full-bodied reds suited to the California terroir.
