About Us / Keller Estate Winery History: Keller Estate is a true Estate: from vine to bottle everything is done at our property. Keller Estate is part of the California Sustainable Winegrowing Alliance. The estate-grown fruit is handpicked in the cooler mornings and delivered to the winery within minutes. White wine grapes go directly into the press in whole clusters and the juice is allowed to run freely. Red wine grapes go directly into the destemmer to prevent excess astringency. The juice is gently moved by bins to the fermentation tanks.
