About Us

In April of 2019, Bartholomew Estate Winery opened its doors, a brand new winery in the heart of Bartholomew Park in Sonoma Valley, California. The winery and tasting room are located in the historic, newly renovated, mission-style building originally built in 1922. Steps away are the mesmerizing outdoor tasting grounds, on a timeless Oak Knoll, where guests can enjoy the breathtaking views of our organic vineyards and the hills beyond, while enjoying our estate wines.

The winery was formed by Anna Pope, as Trustee of the Frank H. Bartholomew Foundation (owner and operator of Bartholomew Park), and noted Winemaker, Kevin Holt, to honor the legacy of the Bartholomews. After many years of living on this beautiful property, in an act of great generosity, the Bartholomews established a trust (named the Frank H. Bartholomew Foundation) to protect and preserve it after they were gone.  Their creation of the 375-acre private park, open to the public at no charge, was, and remains, a gift to the community. Bartholomew Estate Winery was created to ensure that the Bartholomew’s commitment to this magnificent place lives on today, focusing on the creation of the most exquisite wines possible from this iconic location, sharing information on California winemaking and viticulture with all those who visit, and supporting Bartholomew Park, as the incomparable community treasure it is. 

In 1943, Frank and Antonia Bartholomew purchased the land, only to discover that it was the birthplace of California viticulture; the center of Count Agoston Harazthy’s rancho, contains the sites of his residence and original winery. Excited by their discovery, they began to restore the historic structures and replant the vineyards, which had lain dormant for decades. During their nearly 50-year tenure, the property was home to three flourishing wineries. Prior to their acquiring it, the property had a very colorful and storied life and was deeply rooted in the Sonoma Valley community – visit our history page for more.

Today, in keeping with the Bartholomew’s generous spirit, all profits from wine sales received by the Frank H. Bartholomew Foundation (as co-owner of the Bartholomew Estate Winery) go directly to support the Park. When you purchase wine or join the wine club, you are helping to ensure that future generations are able to enjoy this unique part of the Valley of the Moon.
