Four Napa Valley Wineries Launch Joint Tasting Program to Celebrate B Corp Month

Four Napa Valley wineries are joining together this March to celebrate B Corp Month with a collaborative tasting program aimed at highlighting purpose-driven winemaking. Artesa Winery, Clif Family Winery & Farm, Spottswoode Estate Vineyard & Winery, and Trois Noix Wine—all certified B Corporations—are inviting guests to explore their tasting rooms through a special referral initiative that runs throughout the month.

The partnership, called “B Collaborative,” is designed to encourage wine lovers to visit multiple participating wineries. Wine club members from any of the four wineries will receive two complimentary tastings at the other B Corp locations. Members of the general public can access a two-for-one tasting experience when they mention the B Corp Month Referral Program while booking. Reservations are required or strongly recommended due to limited availability.

Each winery brings its own history and approach to sustainability and community engagement. Artesa Winery, located in Los Carneros, was founded by Spain’s Raventós Codorníu family and opened in Napa Valley in 1991. The winery is known for its contemporary architecture and commitment to responsible farming and female leadership.

Clif Family Winery & Farm in St. Helena was established by Gary Erickson and Kit Crawford, also founders of Clif Bar & Company. The winery integrates organic farming, regenerative agriculture, and locally sourced food into its hospitality experiences, reflecting a strong focus on environmental stewardship.

Spottswoode Estate Vineyard & Winery, also in St. Helena, has roots dating back to 1882 and has been family-owned since 1982. It was an early adopter of organic viticulture in Napa Valley and is now certified biodynamic and regenerative organic. Spottswoode became the first certified B Corp winery in Napa Valley, setting standards for responsible winegrowing.

Trois Noix Wine in Calistoga was founded in 2013 by Jaime Araujo. The winery is female- and LGBTQIA+-owned and emphasizes social change through wine. Trois Noix uses sustainable farming practices and aims to connect people through vibrant wines that reflect both tradition and innovation.

B Corp certification is awarded to companies that meet high standards of social and environmental performance, accountability, and transparency. The four wineries will promote the program jointly through email campaigns, social media, and their own channels. Tasting experiences can be reserved directly with each winery via their websites.

The initiative seeks to strengthen community ties among Napa Valley’s B Corp wineries while offering guests a chance to support businesses committed to positive impact. The program runs for the entire month of March at all four participating locations.
