To begin determining your brewhouse efficiency for a given batch, start with calculating the total potential gravity to be obtained from all grain in the recipe:

  1. Potential gravity points = (grain gravity points * weight) / volume.
  2. Brewhouse efficiency = actual gravity points / potential gravity-points.

How much water do I need for a pound of grain mash? To calculate the amount of water, use 1.5 quarts of water per pound of grain in the mash. The mash should absorb about .125 gallons of water. Then measure your runnings, and sparge up to your boilvolume.

Is Step mashing necessary? Step mashing can arguably produce a more fermentable wort, as more time and care has been given to breaking down all of the compounds in your grains. This is much less of a factor with today's highly modified malts. In the past, step mashing was almost a necessity.

Can I mash it BIAB? Here are a few important points to make about BIAB:**DO crush your grain fine, it will produce better conversion efficiency and there is no danger of a stuck sparge. **DO NOT skimp on mash time, this is more crucial with BIAB, mash for 60-70 minutes to achieve fullconversion.
