Notes

Prep

  1. Ice 7 lb. bags x 3. For chilling.
  2. Strike water 160 degrees.

    Mash

  3. Add all grains to strike water and mix to achieve a uniform temperature of 151-153°F. Rest the mash at this temperature for 60 minutes.

  4. When the mash rest is complete, heat it to 170°F for mashout (10 minutes).

    Boil

  5. Bring the wort to a boil, add 1 oz Sterling hops when boil starts, and boil for 60 minutes.

  6. Add 1 oz of Sterling 15 minutes before the end of the boil.

  7. With 5 minutes remaining in the boil (mash out). Add Whirlfloc tablet.

  8. Cool it!

    Fermentation and Beyond

  9. Transfer the cooled wort to a sanitized fermenter, aerate well, and pitch yeast.

  10. Depending on the yeast strain being used, aim for a maximum fermentation temp in the low to mid 50s°F. When fermentation activity begins to slow, allow the fermenter to warm up to approx. 60°F for a 2-3 day diacetyl rest. Depending on yeast and temp, this step should be completed in about 10-14 days.

  11. Cool to lagering temps over several days. Lager for 3-4 weeks (or longer, if time allows) and use a fining like gelatin or Biofine as needed prior to packaging.
