Jason Fullmer is a winemaker, entrepreneur, and beverage production specialist with nearly two decades of experience across Napa Valley and California's Central Coast. Having mastered every stage of beverage production, he founded Mercenary Canning Solutions in 2018 to give small, independent producers access to the same high-level packaging and operational support typically reserved for larger companies.

Since then, Mercenary has evolved from a mobile canning operation into a fully integrated production partner for wineries, breweries, and beverage brands across California. Following the expansion of Mercenary Premier and the acquisition of the former Baileyana Winery facility, Jason combines deep winemaking expertise with a practical operator mindset to deliver reliable solutions that help clients streamline operations and build successful, long-term brands.
