Boulder, Colorado’s Avery Brewing Company has sold a minority stake to Spain’s Mahou San Miguel.

Mahou San Miguel, which is family-owned, is the largest Spanish brewing company.  They own 45 beer brands, few of which are widely available in the U.S.  MSM already has a presence in the US craft beer market, having bought 40% of Founders in 2014.

Avery had been rapidly ramping up production in recent years, and was known to have been seeking a partner.  Their press release didn’t specify the size of the purchased stake; if it is 25% or greater, Avery will no longer be considered a Craft brewer by the Brewers Association.
