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 Gravity Wine House in Sonoma County.
Director of Winemaking
Caroline Davis, our Director of Winemaking, is also Associate Winemaker at Pisoni. A devotee of the sciences since childhood, starting with a love of space and astronomy, Caroline feels fortunate to have come across the science of wine while studying Biology at Pomona College. This led Caroline to earn her Master’s in Viticulture and Enology at UC Davis. Her training and work as winemaker serve her beautifully at Gravity, where she wears many hats—selecting new clients with care, liaising with existing clients throughout the production process, heading laboratory development, and supervising large scale logistics. A quick study, Caroline coordinates operations at the Wine House with a sense of discovery and aplomb.
She continues to enjoy learning new skills. A seasoned traveler, she has worked harvests at wineries from a small Grand Cru in Burgundy to a large commercial facility in Australia. At home, she is learning woodworking and welding and spending time with her dog, Bear.
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 Assistant Winemaker at Gravity Wine House, Malenca, is also 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 tracking wines in the cellar or analyzing 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.
