About Us / Charter Oak Winery History: Charter Oak Winery is a small boutique producer of one of the most exceptional California Zinfandels made by winemaker Robert Fanucci. Charter Oak wine is unfined and unfiltered. The grapes are fermented on natural yeast. We believe the secret to our success is the natural fermentation and the punch down of the cap with hand-made wooden tools, which is done religiously over and over. The wine is in the truest sense handcrafted. We guarantee that you can taste the difference in every bottle of our wine in comparison to mass-produced wines.
