So what exactly is a craft brewery? It is a small brewery that is independently owned and produces all malt beers without the use of flavor enhancers. Some of the larger, more well known craft breweries include Boston Brewing Company, maker of Sam Adams, and New Belgium Brewing, maker of Fat Tire. White Breast Brewing will obviously be much smaller than these but it gives an idea for styles of beer. Iowa has a small number of craft breweries, including Olde Main in Ames, Worth Brewing in Northwood and Hub City in Stanley. Of course there are also the more well known brew pubs such as Raccoon River, Court Avenue and Rock Bottom in Des Moines.
The I Am A Craft Brewer video created by Greg Koch of Stone Brewing and shown at the 2009 Craft Beer Conference really lets you feel what the industry is all about.
The Brewers Association also has a great history of craft brewing on their website.
