  13. After high krausening subsides (3-4 days) add 1.5 ounces each of Idaho #7, Idaho Gem, and PINK (ID-158) hops to fermenter for dry hopping.
  14. After 7-8 days of wort in fermentor and fermentation has slowed significantly, transfer wort to Corney keg and allow secondary fermentation.
  15. After 2-4 days of secondary fermentation, refrigerate Corney keg. Force carbonate with pressurized CO2 after 1 day of refrigeration.

    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 seemed natural for me to carry on the family tradition by brewing an IPA featuring Idaho-sourced ingredients. Enjoy what Idaho has to offer!
