NAPA, Calif., Bronco Wine Co., a family-owned leader in the U.S. wine industry, announced its partnership with Napa Valley’s Brilliant Mistake and Paso Robles’ WHEN SHE WAS KING, both founded by John and Stacy Reinert. Effective March 6, 2026, this strategic alliance marks a significant step for Bronco Wine Co. and the boutique California wineries, expanding national wholesale distribution in the premium wine category.
Bronco Wine Co. continues to broaden its presence across wine tiers, including premium and luxury segments, through strategic partnerships and proprietary brand development. The collaboration with Brilliant Mistake and WHEN SHE WAS KING represents the company’s most substantial move into the premium wine space to date.
“Brilliant Mistake and WHEN SHE WAS KING embody the disruptive energy and bold storytelling defining the next chapter of premium wine,” said Casey Tedd, Chief Commercial Officer of Bronco Wine Co. “Both brands stand out for their strong identities and shared commitment to quality. We’re confident in the distinctive voices they bring to the market.”
Under this partnership, Bronco Wine Co. will provide national and international sales, marketing, and distribution support for select wines. The initial rollout includes three wines: Brilliant Mistake Napa Valley Cabernet Sauvignon, WHEN SHE WAS KING Smoke, and WHEN SHE WAS KING Mask—all crafted by renowned winemaker Maayan Koschitzky, who will remain as primary winemaker.
“Our partnership focuses on producers whose visions align with our long-term goals,” said Dom Engels, CEO of Bronco Wine Co. “From the moment we encountered these wines, the team was impressed by both the packaging and the narrative, as well as the quality inside. It became clear we could amplify what John and Stacy had built.”
For the Reinerts, the partnership provides a unique opportunity to scale without compromising their creative vision. “Stacy and I weren’t actively seeking a partner, but everything aligned,” said Reinert. “Partnering with a team that believes in our brand and shares our willingness to take risks made Bronco the perfect fit. We look forward to introducing more people to our wines and their unapologetic spirit.”
