Procedure
Water Amounts Calculator
Target Final Boil Volume: 11 gallons  
Evaporation Rate: 1.5 gallons per hour  
Boil Time: 60 minutes  
Runoff Volume Needed: 12.96 gallons 11 gallons (final boil volume) ÷ 0.96 (cooling) + 1.5 gallons (boil evaporation)
Grain Amount: 26 pounds  
Grain Absorbtion: 5.2 gallons  
Total Water Needed: 19.16 gallons 12.96 gallons (runoff) + 5.2 gallons (grain absorbtion) + 1 gallons (equip. loss)
Mash Water Needed: 8.65 gallons based on 1.33 quarts per pound of grain
Sparge Water Needed: 10.51 gallons 19.16 gallons (total water) – 8.65 gallons (mash water)

 

Calculations derived from Ray Daniels' book Designing Great Beers.

Doughed in at 140F and did protein rest for 15 minutes. Recirculated to bring mash up to 154.  It took nearly 30 minutes to get there.

Mashed at 154 for 60 minutes

I think my water amounts are a little high.  I am not losing much to equipment loss, nor am I boiling off more than a gallon.  I think I can cut my water amounts by about 1.5 gallons next time.  I will verify when I move the beer from the primary to the secondary.

I put my hops in hop bags as opposed to directly into the wort
