PETER KIRCHNER
WINEMAKER

Peter has a degree in biology and a love of the outdoors. His began his winemaking and grape-growing career working in vineyards in the Santa Cruz mountains and Santa Clara Valley. As his passion for wine grew, he completed the winemaking certificate program at UC Davis. He has been making wine and managing vineyards since 2006, and is constantly trying to improve his craft, looking for ways to produce the best wine possible.

Peter strongly believes that the most important component of a great wine is the fruit that goes into it.  In addition to his wine-making, he spends a good deal of his time working with the viticulture crews from Coastal Vineyards on the property to ensure the grapes are reaching their optimal flavors.  By implementing both meticulous and gentle winemaking techniques, he lets the fruit speak for itself and showcase the micro-climate and terroir of the vineyard.
