The San Francisco 49ers and Clover Sonoma, a third-generation family-owned and operated dairy based in Santa Clara, Calif., announced an exclusive partnership to bring together the two beloved Bay Area brands. As part of the partnership, Clover Sonoma will become the “Preferred Milk of the San Francisco 49ers,” which will include packaging, promotions, a holiday eggnog sweepstakes, advertising, and in-stadium and digital media.

“We always appreciate the opportunity to partner with a local family-owned brand that carries strong name recognition among the faithful, so we couldn’t be happier to welcome Clover Sonoma to our team,” said Kevin Hilton, 49ers vice president of corporate partnerships. “For generations, they’ve been a high-standing and charitable brand, and we look forward to working with them to find innovative ways to entertain and benefit our fans.”

Key assets of the campaign include Clover Sonoma’s inclusion in the 49ers Safeway Shopper program, which includes the release of a 49ers-branded holiday organic eggnog with in-store marketing through the end of the year. Additionally, the 49ers Facebook channel will conduct a fan caption contest where winners will see their caption featured on a co-branded billboard and receive two club seats to one future 49ers home game, Clover Sonoma said.

Clover Sonoma will also become the entitlement partner of Los 49ers, the team’s official Spanish Radio Channel, where games are broadcast via web stream. Cal-Hi Sports Report, the largest high school sports show in California and a 49ers enterprise, will feature a Clover Sonoma branded event titled “Milk & Cookies with the Rookies,” the company said.

“As a 49ers fan, I have always admired the organization’s focus on authenticity, philanthropy, diversity and community,” said Kristel Corson, Clover Sonoma’s vice president of sales and marketing. “Aligning with the 49ers allows us the opportunity to make a bigger impact in the Bay Area, and we’re excited to bring Sourdough Sam and Clo the Cow together for some laughable moments that will inevitably bring cheer to our dedicated fans.”
