Who is this "Anheuser-Busch" they speak of? It's been AB-Inbev since 2008. They've owned SAB Miller since 2016. If you chase the tail all the way back to the beginning, you end up at Interbrew, the parent company of Stella Artois.
The Brewer's Association, by the way, argues that if AB-Inbev owns you you aren't a craft brewery.
Less than 25 percent of the craft brewery is owned or controlled (or equivalent economic interest) by a beverage alcohol industry member which is not itself a craft brewer.
