Brewed 11/8/20. Mash in w 16.5 L, 2 g CaCl2 and 2 ml lactic acid.
Rest at 130 F for 10 minutes, raise to 144 F, the pull first decoction. Rest decoction 20', boil 20', return to main mash which settles at 154 F. Hold until 1 hour then pull decoction, quick boil, return to main mash to mash out. Adjust temp to 170 F for mash out. Sparge with water containing 3 g CaCl2 and 2 ml lactic acid. 2.5 L starter refed on brew morning with 500 ml fresh wort. Fermentation at 50 F.
Racked to keg 12/2 and krausened; added 1 L of actively fermenting wort (saved from primary) repitched with yeast saved from intial seed. Fermentation visibly picks up as judged by CO2 evolution. Hydrometer sample measures 1.013 24 hrs after collection. Temp allowed to rise until mid-50's, then to 65 F for two days before returning to keg fridge at 50 F on 12/10.
After 1.5 months of lagering at about 34 F, hydrometer sample measures 1.013.
Tasting notes: Good helles bock, drier than usual - but maybe now too dry? Could use a touch more maltiness, perhaps up the munich a tad. And I just don't know about 833, I don't think I like i it as much as 860 or 838...
