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.
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.
Lead Bottling Technician
As the Lead Bottling Technician here at Gravity Wine House, José is the eyes and ears on our mobile bottling line. With nearly twenty years of experience both in cellars and on bottling lines, he can pinpoint a problem just by listening to bottles pass through the sparger, filler, corker, and countless other components of the line. In this sense, we view José as the grand conductor of a bottling orchestra, ensuring all pieces and parts move and work together in harmony. He thrives in fast-paced environments and loves collaborating with customers on their specific bottling needs.
A Sonoma County native, José grew up among vineyards in Cloverdale, California. When he’s not on the bottling line, he can most likely be found with his family, cruising on a boat at Lake Sonoma or enjoying a live soccer or basketball game.
The Enologist in our Analytical Laboratories, Malenca, is a seasoned veteran in the lab. Originally from Berkeley, California, a love of learning led her to the East coast where she received her BA in Chemistry and Biochemistry from Haverford College. Back on the West coast, a love of wine persuaded her to receive a Master of Science degree in Viticulture and Enology from UC Davis. When Malenca is not analyzing clients’ wines in the lab, she enjoys cooking delicious meals while drinking an aromatic white at home with her pup, Munchie.
Malenca thrives in the lab, where she solves problems with efficiency and care, answers perplexing questions using analytical data, and helps our clients create truly special wines through science.
