Stone Brewing was founded in 1996 by Greg Koch and Steve Wagner in San Marcos, California, with a clear mission: to brew bold, flavorful craft beers that challenged the mainstream. Starting in San Diego County, the brewery grew steadily to become one of the most recognizable names in American craft brewing, eventually ranking as the 10th largest craft brewer in the United States. Over the years, Stone has changed ownership — most recently becoming part of Duvel Moortgat's portfolio, with production tied to Firestone Walker Brewing, a fellow California craft brewery also founded in 1996. Stone Brewing built its reputation on assertive, hop-forward beers that pushed boundaries and celebrated bitterness long before it became fashionable. Their portfolio spans a wide range of styles, from West Coast IPAs and imperial stouts to sours and beyond, always staying true to their unapologetically bold brewing philosophy. The brewery expanded its global presence over the years, bringing its craft beer ethos to audiences far beyond California. Stone IPA stands as the brewery's flagship beer and a landmark in the American IPA category, widely credited with introducing countless drinkers to the world of craft beer. Despite its corporate transitions, Stone Brewing remains a defining chapter in the story of the American craft beer revolution.
