Partners Josh Baker and Jason Fullmer
Expand Production Services with New Anchor Facility; Available for Harvest 2026
June 23, 2026 (San Luis Obispo, CA) — Mercenary Premier announced the acquisition of the former Baileyana Winery in the Edna Valley. The company, which began as Mercenary Canning Solutions under founder Jason Fullmer, expands its successful mobile bottling business to now offer full custom vinification services at the new anchor facility. Joining Fullmer in the partnership is Josh Baker, trusted veteran winemaker and production executive. Together, the pair brings 35 years of combined winemaking and beverage production experience. Steve Adamski and Ty Green serve as the company’s legal and financial advisors.
“What started as a mobile canning operation in 2018 has grown into something far bigger than I imagined,” said Fullmer, co-founder of Mercenary Premier. “Our best-in-class packaging is a proven model with repeat business and a busy calendar. Partnering with Josh allows us to offer winemakers a complete production solution carried out by someone they trust. His expertise, reputation, and our shared vision make this the right next step.”
The vision is to become California’s leading destination for custom vinification and comprehensive winemaking services, serving winemakers and beverage producers at every stage of the process. Anchored by the Edna Valley facility and ready to begin operations for harvest 2026, Mercenary Premier expands into full-scale winery processing, capable of high-end red and white wine production, barrel and tank aging programs, case good storage, and dedicated winemaking support. To guarantee exceptional quality at scale, the facility is outfitted with the strongest winemaking equipment available in the area, featuring two fully inert Pellenc SPC240 Smart Presses and a Pellenc H1000-70 Destemmer equipped with advanced Kliner technology. The newest available laboratory technology assures reliable, timely analysis in-house. This expanded suite of vinification services builds upon Mercenary’s proven mobile business and positions the company as the go-to winemaking partner in the state.
“Jason and I have worked together for years, and I’m proud of the business Jason has built. We share the same mentality as owner-operators and this approach will carry us into the next chapter,” said Baker, co-founder of Mercenary Premier. “A permanent production home in the Edna Valley, at a facility made for high-end production at scale and run by proven operators, is the foundation we need while the mobile business keeps serving producers across the state.”
Clients seeking a trusted partner with technical expertise, industry-leading equipment, production capacity, and packaging solutions to make harvest 2026 a success are invited to connect with Baker and Fullmer.
