In establishing a Community Supported Winery (CSW) in Petaluma, California, Glasshaus Wines is creating a sustainable model that benefits both its contributing members and the local community.


Benefits for Members

Members provide the working capital necessary for wine production through the purchase of Shares prior to harvest. Each Share equals one case (12 750ml Bottles) of wine each vintage year and is offered at 20% off the pre-set vintage retail price. As a form of appreciation for continued support, members accrue an additional 2% discount (Lifetime Maximum 10%) for each qualified purchase year of membership and are offered "Early-Bird" Shares for subsequent vintages 30 days before new members. Members are consulted for quality feedback, future varietal production and social program selection. Member demographics determine charitable fund distribution.

Members are also kept well informed of the overall operations through:

  • Monthly Glasshaus Community News
  • Monthly Winegrowing Reports & Weather Analyses (Apr-Oct)
  • Complete Harvest & Winemaking Data
  • Annual Report of Operations

Members are also invited to our members-only Release and Harvest Parties.

Benefits for the Local Community

Our members pledge their support because they share our purpose-driven values. This desire for connection and contribution extends beyond the confines of Glasshaus to our winegrowers, artisan neighbors and the causes that we support. In addition to increasing awareness, we offer the following benefits.

Our strong partnerships with our local winegrowers provide the foundation for our mutual success. Our winemaking philosophy of preserving and promoting the unique characteristics of the local terroir benefits the entire local wine growing community.

"A rising tide lifts all boats" is an aphorism we intend to prove. We are incorporating a marketplace for local artisans to offer their unique, one-of-a-kind products as "add-ons" to our Member's Wine Shares. 

Lastly, and most importantly, it is commonly understood that youth mentoring programs lead to improved behaviors, attitudes and academic performance. We strive to pledge 20% of our profits to support local organizations and local chapters of national organizations that provide successful youth mentoring programs.
