Original Recipe Data
Recipe Grain Weight: 20.750
Recipe Volume: 10.000
Recipe Gravity: 12.4
Absorption Factor: 0.125
Desired Kettle Volume: 12.000
Grain Displacement Factor: 0.08
Wort Lost to Dead Space: 2.00

No-Sparge Results
Grain Scale-Up Factor "S": 1.227
Total Grain Required "Wg": 25.468
Mash Thickness "R": 0.675
Total Mash Water "Vm": 20.367
Runoff Gravity: 8.9

50% efficiency = very low because this is using the no-sparge method.

whirlfloc at 30 minutes
servomyces at 10 minutes

** Remember to add 2 gallons to the Polarware mash tun to make up for the floor space below the false bottom

fermentation procedure:
california ale yeast WLP001
ferment at 68F, 6-7 days maximum,
diacetyl rest at 70F for 24 hours
transfer to a clean 5 gal carboy and drop the temperature to 52F for 2 days
to pull the yeast out set the max temperature back to 68F and start the 12 day dry hopping at this point, letting the temperature slowly creep back up to 68F over a few days. Leave it at 68F for the bulk of the dry hopping regiment. Dry hop twice, once at day 0 and once at day 6 for 12 days total, adding no more than 2.5oz. of hops total. (This is why the dry hop regimen is listed twice in the recipe) Drop it down to 33F for transfer 11 days into the dry hopping, so do about 1 day of cold conditioning before transferring it to the serving tank.
very gently stir the dry hopping additions to keep the hops in suspension


What will the gravity of the pre-boiled wort need to be?

Here again I use the dilution formula to find the beginning gravity:

Beg Gravity=(End Volume * End Gravity ) / Beg Volume

which breaks down to:
Beg Gravity=(6 * 60) / 8

which is 45 gravity pts or 1.045 OG. Thus, I need to start with 8 gallons of pre-boil wort at 1.045 to get 6 gallons at 1.060 after the boil.

final gravity: 1.015
