About Bison Brewing Company

Bison Organic Beers is an artisanal company producing high quality and innovative beers for the burgeoning craft beer marketplace. They currently sell their organic beer in 12 states, including iconic beers like Organic Chocolate Stout and Organic Honey Basil Ale.

Established 1989, Berkeley, CA Bison Organic Beers is an artisanal company producing high quality and innovative beers for the burgeoning craft beer marketplace. They currently sell their organic beer in 12 states, including iconic beers like Chocolate Stout and Honey Basil Ale. Each recipe began as an enlightened experiment to delight, satisfy and challenge the brewers and their customers. Today’s portfolio of bottled beers reflect the best experiments—balanced, drinkable beers with unique ingredients, and distributed to independent stores.

In 2002, Brewmaster Daniel Del Grande felt organic certification was important to sync his profession life with his personal life. He was influenced by the simple fact that growing crops without chemical fertilizer, herbicides, and pesticides is the best way to protect the environment, sequester carbon, save energy, and protect farm workers. In 2014, organic food and beverage composed 5% of the US grocery budget, and Bison is one of less than 12 brewers of 100% organic beer, in a nation of over 4,400 brewers. Del Grande describes his business as “More than a Beer. A Movement.” In 2009, Bison became the first B Corp certified brewery.

Employees at Bison self select themselves for two core values. First, they must enjoy both the solitude of the outdoors and the company of friends, and recognize that well made food and beverages bring pleasure into everyday life. Second, they must give back to the community in a company supported projects like raising money for the Humane Society or growing hops locally at community gardens.

We know that the small choices consumers make every day have the power to change the world, but there is so much "greenwashing" out there, we immediately saw the future power of the B Corp status for consumers. Once becoming certified, we learned how much more we can do, and each year strive to improve our impact. Bison is proud to be part of this community of exceptional entrepreneurs and companies because our goods and services are building a new sector of the economy which harnesses the power of private enterprise for public benefit.

The Change We Seek®

Brewmaster Dan Del Grande has been described as the Johnny Appleseed for organic beer, teaching us why it is important to ask that organic beer be on tap at your favorite local restaurant or bar. He explains: “A restaurant that purchases just one keg of organic beer per week for a year creates demand for a farmer to convert a football field size piece of land from conventional to organic agriculture -- that’s a HUGE impact each local local watering hole can make!”

Organic products, from field to consumer, are the best way to protect the environment, save energy, and ensure sustainability of American farming. The Organic logo means the food is GMO-free. Organic farming nourishes and protects growing plants with soil and microorganisms. Conversely, “conventional” farming relies on dousing plants with chemical fertilizer, pesticides, and herbicides, which increases soil erosion, pollutes waterways, and unnecessarily relies on petrochemical consumption.
