Notes

Mash Draw first (thick) decoction with 90 min remaining in acid rest (wait 30 min): 15min to rise to 122F, 15min rest, 15min to rise to 156F, 15min rest, 15min to boil, 15min boil ---------- 90 min Second decoction (thick): 15min to raise to 156F; rest 15min; 15min to raise to boil; 15 min boil ----------- 60 min Third decoction (thin): wait 30 min 15 min to rise to boil, 15 min boil ----------- 30 min Authentic Germany mash schedule. Attempt to draw decoction from the thickest portion of the mash. Some sources recommend that each decoction amount be given a 15 minute saccharification rest at 158 F (70 C) before boiling it. ======== Yeast is 500mL of PURE SLURRY (~1600 billion viable yeast cells) repitched from 5g of munich helles, brewed 3-4 wks ago. Watch out for equilibrium temp on acid rest (rose to 100F instead of 95F). Go 15% bigger on all decoctions to account for transfer heat losses. Note the higher efficiency (82% instead of 75%) from the decoction. All pH measurements taken at 80-90F, unless stated otherwise. First runnings: 5.35@100F; 1.096@70F Sparge pH: 5.43@100F Final runnings: 5.45@100F; 1.058@70F Pre-boil, total wort: 1.079@65F; 14.5g@200 Pitched yeast 6hrs later at 48F; oxygenate for 45s per 5g carboy.
