Mahou San Miguel, the Spanish brewing group, bought a 30% stake in Founders in December 2014 and increased that to a controlling holding in August 2019, with the two founders retaining a small share each. The Brewers Association, which defines American craft brewing by ownership as well as scale, revoked Founders' craft designation as a result.
Whether that changes anything for a drinker is a genuine argument rather than a settled question. The brewing operation is still here, the recipes did not change, and the beer is made by the same people in the same building. But if buying independent matters to you, Founders no longer qualifies by the industry's own definition, and there are a dozen genuinely independent taprooms within a fifteen-minute drive.
Founders also settled a racial discrimination lawsuit brought by a former employee out of court, a case that drew national coverage in 2019 and led to a period of significant change at the company. It is part of the record and worth knowing if you are the kind of drinker who asks.
None of this is a reason not to go. It is a reason to go informed, which is the same standard we would apply to anything else on this site.
