Michael Zardo

Operations Manager

Winemaking is complex. Then consider running an efficient cellar with various clients and a non-stop array of intersecting operations: Beyond complex. Michael combines two decades of winemaking and cellar management operations to hone in on efficiencies and run a well-choreographed cellar team—all while considering the best scenarios for the wine.

When he’s not in the cellar, you can follow the smoke signals to find Michael acting as the pitmaster for the many great meals he prepares for his family and friends.

Jeff Pisoni

Jeff Pisoni

Founder

Jeff loves making wine—and considers himself a lifelong student of enology. It’s the craft that his father inspired him to explore, study and pursue since he was just a toddler. Through his role as a winemaker, Jeff developed a passion for exchanging information and insights with the winemaking community, all with the goal of driving for higher quality wine and methods. This is the inspiration from which he and his family established the dedicated Gravity Wine House facility in Sonoma County.
