About Us

The Petaluma Cooperative Creamery begins distributing Clover-branded dairy products in the Petaluma, CA area. Soon thereafter, Clover products began showing up all over Northern California.

Clo the Cow first appears as the official mascot for the Clover Brand. She has since grazed billboards in Northern California with the dairy best puns the state has ever seen.

Gene Benedetti and five partners acquire the wholesale distribution business from California Cooperative Creamery (formerly known as Petaluma Cooperative Creamery) and Stornetta’s Dairy in Sonoma, CA in 1977. As a result of this acquisition, Clover Stornetta Farms, Inc. is born.

Clover Stornetta opens its new state-of-the-art milk processing facility at the Petaluma location. With a new fully automated facility, Clover is able to do three times the volume of the old plant with virtually the same manpower.

Clover rejects Monsanto’s newly developed “wonder” drug: rBST—a controversial synthetic growth hormone designed to artificially stimulate milk production in dairy cows. Clover pledges to avoid all use of rBST and goes on to develop and adopt rigorous quality standards set by the North Coast Excellence Certified program. Clover leads the way in practicing sustainable agriculture and humane treatment of cows—still adhered to today.

Clover becomes early adopters of the organic movement and adds dedicated products to the lineup.

Clover Stornetta Farms becomes the first dairy in the U.S. to be certified by the American Humane Association for its animal welfare program.

Clover becomes B-Corp Certified—passing with an impressively high score. We remain B-Corp Certified today.

Clover Stornetta Farms officially rebrands as “Clover Sonoma”, embracing the region it calls home. The brand evolves the North Coast Excellence Program into the Clover Promise of Excellence.

Clover Sonoma partners with independent, Colombian-based dairy, food and nutrition company, Alpina, to facilitate growth in the U.S. Market.
