Notes
  1. Bring the wort to a moderate but rolling boil, add the Burton Water Salts and set a timer for 90 minutes.
  2. At 60 minutes, add the pre-measured bittering hops and Irish moss.
  3. With 10 minutes left, add the yeast nutrient
  4. At the end of 90 minutes, flame-out and add the flavoring hops. Actively steep this hop addition while monitoring the temperature.
  5. When the temperature drops to 180F, add the aroma hops. Actively steep until the temperature drops to 170F.
  6. Immediately start cooling the wort to about 75F.
  7. Aerate, take a gravity reading, and add the yeast. Move the fermenter to an area that will remain 70F or so throughout fermentation. Ferment for 7-10 days until FG is reached and the beer is clear. After fermentation is done, add the dry hops and condition for another 7-10 days.
    Hop Notes:
    15.84 Bittering Units Galena pellet hops
    • Divide 15.84 by the Alpha Acid value on the bittering hop package to determine the weight you will need. Example: 15.84 BU / 13.2 AA = approximately 1.2 oz hops.
