Producers confronting climate change head-on: Château Maris has taken green winery construction to a new level, building an entire facility out of lightweight, organic hemp-straw bricks that continue to capture and sequester carbon dioxide over many years as they harden.” The Wine Spectator. – From the beginning, Château Maris focused on sustainable winemaking practices in both the vineyard and the cellar. We converted old, unhealthy vineyards to organic, biodynamic ones. Then we built an environmentally friendly, carbon-neutral hemp brick cellar, the first of its kind in the world. Most recently we became a B Corporation, joining a community of like-minded people, working with businesses that inspire thinking differently about solutions to environmental and social issues.
