Our Team

Landon Ziedses des Plantes

Production Manager

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.
