Notes
  1. Full volume batch sparge
  2. No chill
  3. 30 minute hop addition to compensate for no chill (1st time trying it like this).
  4. 1st version

    Results:
    Overshot mash temp(156)
    Water Amounts are spot on
    Add a few rice hulls for total volume sparge on a large batch.
    Used five gallons for mash , then topped of with remaining water. Then collected runnings all at once.
