This batch employed a Hochkurz Step Infusion Mash.* Dough in with hands for very thick acid rest at 100°F for 20 min. Infuse with boiling water for protein rest to reach 122°F for 25 min. Infuse with boiling water to reach 145°F for maltose rest/conversion for 35 min. Infuse with boiling water to reach 158°F for dextrinization rest until negative iodine test. Mash out at 167°F before lautering. Collect 8 gal wort, full volume is at 10° Brix before boil.
- All added water volumes are rough estimates. Temperatures were achieved with infusion of near boiling water at each stage. Acid and protein rest were very thick. Later rests were thinner to get better conversion.
Bring wort to boil for 30 minutes before hop addition at 30 min. Take off boil at 90 min. Brix off burner is 14°.
Bring volume to 50 degrees overnight before pitching yeast...collected ~ 5 gallons. Need to work with efficiency some more. Always have DME on hand and brew for 6 gallons so I can lose cold break.
