Silas York (of the York Family) becomes a partner in A. York and Sons.

By 1902 A. York and Sons Winery was making 40,000 gallons of wine per year. They sold locally but also shipped wine to the East Coast in railroad tank cars.


The Dallidet vineyards, lost to the Commercial Bank, are subdivided for housing as the La Viña Tract.


A. York and Sons Winery signs a contract to sell large amounts of wine to a Wine Merchant in San Francisco. The contract is the first one to specify that the wine must be shipped in Puncheons, must be transported by wagon to the train station and shipped according to instructions by the Merchant.

A. York and Sons purchase additional land and plants grapes.

The York family expand the winery. The family makes the bricks and adds extensions to the original winery.


Frenchman Adolphe Siot sells his land and winery to Joe Rotta. Adolphe becomes Joe Rotta’s mentor and teaches him how to care for the vineyards and how to make wine. Their friendship and working relationship continues into the 1920s.


Joe Rotta buys the Siot vineyard and winery, heralding a period of Italian dominance, with the Dusi and Pesenti families, of county grape growing and winemaking through the 1960s.
