Every harvest each member winery brings 1,000 pounds of designated grapes to a member crush pad to kick off a day of hard work and collaboration. The juice is divided equally, with which each winemaker returns to their own winery. This source material – the shared juice from collectively grown grapes – is an open platform for each winemaker to build their own expression of each Open Source wine.

Although the labels of each of the six look similar, a careful eye will notice that the topographical lines on each are slightly different, etching the landscape of each winery estate. Each winery produces about 23 cases of Open Source wines each year, and it is available upon release at Co-Op events and promotions and in our respective tasting rooms until it is sold out.

Beginning with a series of Chardonnay releases in 2016, we have produced an Open Source wine each year, with the exception of 2020 when the Covid-19 pandemic interrupted our collective lives. The Open Source series is a unique way to see how a skilled winemaker makes his or her mark on a wine. Proving that while a great wine is made in the vineyard; it can take the form of many expressions.
