25 September 2011 – Made 1.7 l starter of WLP565 (production date 28 July 2011) w/ Wyeast Yeast Nutrient on a stir plate.

26 September 2011 - Brewed by myself. Doughed in with 5.1 gal (1.5 qt/lb) at 164 degrees. Adjusted with .5 gal boiling water. Rested at 154 for 60 minutes. Adjusted with 1 tsp phosphoric acid for mash pH ~5.2. Batch sparged with 4.5 gal at 180 degrees for 10 minutes at 165 degrees (added sparge water a little slow, undershot target 170 degrees). Adjusted sparge water with 1 tsp phosphoric acid for water pH of 5.0 (overshot sparge water pH, next time use ½-¾ tsp)

Yielded 8.15 gal of 1.044 wort (mash efficiency 70.4%).

Removed .5 gal wort.

Boiled for 90 minutes yielding 5.85 gal 1.058 wort (evaporation rate 15%/hr or 1.2 gal/hr).

Chilled to 67 degrees F in 26 minutes. Racked 4.8 gal to Better Bottle (~1 gal lost to trub and hop sediment).

Aerated with pure O2 for 35 seconds then pitched entire starter of WLP565 and vial of WLP645. Temperature control ceiling set to 80 degrees F.
