Glasshaus Wine Company is a Community Supported Winery (CSW) dedicated to producing ultra-premium Sonoma Coast (Petaluma Gap) wines and sharing our profits with social programs that benefit local communities.


Like some community supported agricultural models, our contributing members pledge in advance to cover the anticipated costs of winegrowing and winemaking. In return, they receive guaranteed Shares of our artisanal, small-batch production, 100% transparency during the winegrowing and winemaking process, as well as the satisfaction gained from supporting their local community.

By focusing on direct sales to members, who have provided the necessary working capital in advance, we largely avoid the need for traditional distribution and much of the financial burden of marketing. These savings are passed on to our members (20% discount) and allocated to support social programs (20% donation).

Our goal is to build a sustainable wine business dedicated to becoming a pilar in the Petaluma community and to donate more than $150,000 annually to youth mentoring and educational programs.




A New England native and Petaluma resident, GM/Winemaker Rodney Gagnon is the driving force behind Glasshaus. Rodney’s wine obsession began in 1996 while cycling through the vineyards of Burgundy, France. Leaving behind a 20 year career developing software products and services, Rodney completed formal wine appreciation, wine business and winemaking programs at Boston University and UC Davis. Since 2010, Rodney has been spearheading sales, marketing and wine production for custom winemaking operations in Sonoma California and Bordeaux France. Glasshaus was born to satisfy his passion for Pinot Noir and Chardonnay and his need to connect with and help build stronger communities.
