Fast Facts of Female Winemakers in California

Hannah Weinberger is the first recognized woman winemaker in California. After her husband's death in 1882, she became the first female winery owner and winemaker in Napa Valley. She ran the Weinberger winery until Prohibition laws closed it in 1920. The winery and homestead are on the National Register of Historic Places. 


Josephine Tychson, a contemporary of Weinberger in Napa, was a winery owner, but not a winemaker. She completed the family winery in 1886, following the death of her spouse, and operated the winery until 1894.


Mary Ann Graf, the first woman to receive an 

enology degree from UC Davis, is the first woman winemaker of the modern era being defined as post 1965 when the Napa and California wine country began its renewal as a serious world wine making region.


Graf, who received her degree in 1965, first worked as chemist and assistant winemaker with Gibson Wine Co. in Central Valley before being appointed winemaker at Simi Winery in Healdsburg in 1973. She was followed at UC Davis by Zelma Long in 1970, whose first position was at Robert Mondavi, Barbara Lindblom in 1972, Merry Edwards in 1973, Sandra Belcher in 1974, Milla Handley in 1975, Alison Doran-Green in 1976, Julianne Laks in 1977, and Cathy Corison, Carol Shelton, and Jill Davis in 1978. Each of these modern-era pioneers is an esteemed winemaker and leadersin the field.


The first Women Winemakers to also be owners to have their names on their labels are...


    1982: Milla Handley made her first Handley Cellars Chardonnay under the Handley label in Mendocino.

    1984: Merry Edwards left Matanzas Creek to devote herself full time to consulting and Merry Vintners, a small winery that she and her family founded in the Russian River Valley. In 1997, she co-founded a business venture that allowed her to produce Merry Edwards wines in Sonoma County.

    1986: Delia Viader founded Viader Vineyards in Napa. Her first vintage was 1989, when she produced 1,200 cases of wine. 

    1987: Cathy Corison made the first vintage of Corison Cabernet Sauvignon in Napa. 

    1989: Lane Tanner instituted the Lane Tanner label in Santa Barbara County.

    1989: Marty Bannister established Bannister Wines in the Russian River Valley AVA.


Hannah Weinberger First Female Wine Maker Controversy

Hannah Weinberger born Oct. 7, 1840, and after marrying John Weinberger in 1871, the couple moved to the Napa Valley. They bought 240 acres and spent three years building a three-story stone winery, which was completed in 1876, with 35 acres planted in vineyard.


After the death of her husband due to a shooting Hannah and her family picked up the pieces and she took a leadership role not typical of women of that era.  She took over operation of the winery and vineyards and also took John’s place as a director of the Bank of St. Helena.


There seems to be controversy over whom was the first wine maker. Some sources including myself have reported Josephine Tychson,

as the first wine maker in California.


 In reality both were pioneers but Josephine’s husband committed suicide in 1886 and Hannah’s husband was murdered in 1882. Thus it appears that Hannah was the first to take over a winery as a wine maker.


Many details of Hannah Weinberger are not known whereas the history of Josephine is more widely published. The Historic Society of Napa is fuzzy on which wine maker or winery owner was first. Desth records make us conclude it was Hannah.


Josephine also had a very interesting story...


Josephine Marlin Tychson (March 5, 1855 – December 18, 1939) was the first woman to build and operate a winery in the U.S. In 1886, she established a winery in St. Helena, selling it in 1894. Its name changed to Lombarda Cellars and is now Freemark Abbey Winery.


Tychson was born in 1855, into a wealthy family from Pennsylvania. John Marlin (d. 1878) and Eliza (née Bower; 1823-1860), her parents, had also lived in Astoria, Oregon; Tychson was one of 8 children. She grew up in Philadelphia before the family moved to San Lorenzo. At the age of 8, her mother died and her father remarried Eliza’s sister. Tychson’s father and aunt were influential from a young age in her development as an independent, young women.


Following the death of her sister Catherine in 1874, she married the Danish farmer, John C. Tychson. Their first child, Annette, was born in 1878. In 1879, the young family moved to Denmark, where John took care of some affairs, before returning to the United States.


They moved to the Napa Valley in northern California, where they purchased a 147 acre vineyard in St. Helena from William James Sayward, a sea captain. They planted the vineyards in 1881, establishing Tychson Cellars five years later.


She lost her tuberculosis-afflicted husband to suicide at the Newland House Hotel in Oakland, leaving her to look after two children and the estate. However, it was during this mourning period that Josephine exhibited a penchant for understanding how to survive. Not only burdened with the upbringing of two children, Josephine was also confronted with the heavy task of vineyard construction and design.

Both she and her foreman implemented an ambitious project for the assemblage of a new wine cellar. The capacity within the newly forged space boasted of being able to contain 20,000-30,000 gallons of wine cargo; an impressive size for its time.


For eight years, Josephine devoted her life to the subtle caretaking of her crops. She not only nurtured her children but also the soil of her land, using her knowledge and upbringing to ensure its’ fertility.


Unfortunately, by 1893, her crops were unable to resist the harmful advancement of phylloxera.

According to an 1890 report by the California Board of State Viticultural Commissioners, the Tychson Winery cultivated Zinfandel, Riesling and Burgundy.


She was a true pioneer and after her winery earned acclaim, Josephine’s name was even listed within the Napa-Sonoma County Directory of 1889-90, as a “fruit grower/wine maker. A first for a female.


As a result, she sold the winery in the following year to foreman Nels Larson; Larson sold it to Anton Forni in 1898, who renamed it Lombarda Cellars after the region of Italy that he hailed from, a name it retained until it went out of business.


Tychson, who never remarried, bought a white house opposite the vineyard. She was described as “an intrepid Victorian widow who could often be spotted riding”.


She died in 1939. Upon her death, the estate was sold to Charles Freeman, Mark Foster, and Abbey Ahern, giving it its name “Freemark Abbey”.


Tychson has been showcased by Napa County Historical Society in the past with a temporary exhibition for her historic contributions to the wine industry in an exhibit titled “Harvesting History,” which documented the early viticulture of the Napa Valley.


Although Josephine’s winery does not exist today, her home still remains —a remnant of her legacy as one of first true female vintners in California. It’s located beneath the Freemark Abbey Gift Shop in St. Helena.


Records support both cases for Hannah and Josephine. Josephine seemed to secure a higher profile in historical documents thus the confusion as to who was California's first female wine maker. We on the other hand celebrate both as pioneers who's names continue to inspire conversation in the Napa Valley and beyond.
