Belgian. The Brazilians own Miller.
Actually, South African Breweries owns Miller.
InBev ownership:
Belgian versus Brazilian:
Its a bit of both. InBev was formed by the merger of Belgian company Interbrew and Brazilian company AmBev in 2004. The headquarters are in Belgium, so you’re mostly right.
SAB Miller is international, but the SAB stands for “South African Breweries LTD” and was the original brewing company. I’m not sure where the center of gravity of that operation lies now (you said the Brazilians own Miller).
