I have had some commercial beers including some good craft beers but Ive never been interested in duplicating what everyone else is brewing. I got into homebrewing for the science but I keep brewing because I know I can ferment things that are truly unique. When I make a new recipe I try to balance things like malt and bitter and carbonation but I dont try to perfectly match any style guidelines, it would be hard if not impossible to find commercial examples of most of the stuff I brew.
