Our Team

Michael Zardo

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.

Landon Ziedses des Plantes

Cellar Master

Landon can do it all. He has over a decade in wine production experience covering everything from the cellar to the bottling line. When a question comes up about a new method or operation in the cellar, ask Landon. He has likely done it. The winery and team also benefit from his artistic side—lifetime of playing music for his own band and a degree in music business & production—and practical skills that come from years spent in the construction field. When you meet Landon, you’ll quickly wonder if he has the unofficial title of Winery Renaissance Man.

Jeff Pisoni


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.

Hannah Gazett

Production Coordinator

Details and connections are Hannah’s forte.  Her background and degree in Biomedical sciences had her scrutinizing medical records that are thousands of pages long to identify and connect data. Turn that focus to wine as our production coordinator, and Hannah acts as the hub of our operation—assembling the details of wine work, schedules and constantly connecting with customers.

Hannah’s love of wine started early with blind tasting while in high school. She followed this passion by working in Colorado wineries until trading the ski slopes for the California coast and moving to Sonoma County.

Cody Zardo

Cody Zardo

Bottling Technician

Cody Zardo loves working with his hands. Combine that with his mechanical mindset and you’ll find him to be the perfect bottling technician for our mobile bottling program. Cody has broad experience in the beer and wine industry: His first harvest with Pisoni Family Vineyards in 2010 was followed by years in cold side brewing. Troubleshooting is his favorite part of the job, and thousands of fast-moving parts keep him on a constant pursuit of perfect operations.If you are searching for Cody after a long week on the line, you will likely find him kayaking down the Russian River—a relaxing detour from the fast-paced world of bottling.
