ferment at Ale, @ 75degrees

Notes

This recipe is from Mark Peterson. He used this to win Gold 2015 in the style. Here, I scaled up batch size to 12gal and increased the OG to result in an abv of about 8%. The other thing I changed was to use kölsch yeast WLP029 since I just fermented a kolsch and the slurry was available. I came across a mad fermentationist article where he used kolsch WY2565. This beer will go into my woodinville rye whiskey barrel, which will be the 4th beer to age in it. Mark’s notes from his batch: can use Southern German Lager white lab original gravity 1.064 mine 1.066 final gravity 1.012 took yeast cake from kolaboration kolsch WLP029 harvested 12/20/16, into 5L flask. Crashed and decanted off rest of beer 2 days later. Added 1/2 canned wort 1.043 OG. Fermented exhuberantly in just several hours. Placed in fridge to cold crash, however it got disturbed and did not get a sufficient drop out. Brew day Friday 1/6/17 at Carvin’s with Jeremy Mitchell did no sparge mash. Added 20gal water and mashed in. CaCL2 10g and gypsum 2 g, 1tsp phosphoric acid. Dough in hit 142F. Recirculated and heated to 154F. pH after reaching temp (sample cooled) was 5.4. Mash 60 minutes, then mash out to 170F. Took about 10 minutes to get from 154 to 170F. Recirculated at 170 for 10 minutes. boiled 90 minutes, added hops at schedule. only 1# Candi syrup 1SRM @ 9 min left in the boil. Collected wort into 2 fermentation buckets and transported home. Poured with vigor into Bru Gear 14gal conical to aerate. Volume is 11.5 gal. took hydrometer reading 1.066. Note this is off from the planned 1.080. Its likely due to the no sparge. took 029 and poured off some of the supernatant. Slurry is about 800ml. Did not do a cell density. Set at ale temp 72F. Pitched at 7:30pm 9:30pm this thing is already fermenting, blowing out the blowoff tube Friday 1/13/17. FG 1.014 Saturday 1/4/17 set at 42F to cold crash. 11:00pm
