  13. After 7-8 days in fermentor, transfer wort to Corney keg and refrigerate.
  14. After 1-2 days of refrigeration, force carbonate with pressurized CO2.

    As a 4th generation Idahoan who lives near where the bulk of Idaho hops, barley, and potatoes are grown, and whose great-grandfather owned a bar & dance hall in Idaho City, Idaho Territory, brewing the beer he sold using nearby Idaho spring water, it only seems natural to brew an IPA featuring Idaho-based ingredients ... and to carry on the family tradition.
