I cant give you final, bottom-line profit, but from a 2010 BA survey, EBITDA (2009) for the respondents was $47 per barrel. It includes over 100 production breweries (not brewpubs) of all sizes (looks like about 10% were greater than 50k bbl/yr in size). This number is pulled down by the under 1k bbl/yr group, who make basically nothing. Edit: Looks like Ab-Inbev is ~$50 per bbl EBITDA. So same ballpark.
