    I'm a 4th generation Idahoan who lives where Idaho hops, barley, and potatoes are grown. My great-grandfather owned a bar & dance hall in Idaho City, Idaho Territory in the 1860's. He brewed the beers that he served using imported and local ingredients, including local Idaho spring water. It only seems natural for me to carry on the family tradition by brewing an IPA featuring Idaho-sourced ingredients. Enjoy what Idaho has to offer!
