I'm interested in running a turbid mash for a lambic. So far, all my brewing has been with a rectangular cooler / batch sparge setup running two equal-volume runoffs to maximize efficiency. I'm wondering how I can make this fit in with a turbid mash schedule.
A description of a turbid mash schedule from Wild Brews:
Dough in with 1 gal at 113F for 15 min.
Add boiling water to reach 126F for 15 min.
Remove 1/3 of liquid; Heat to 190F in small kettle and hold.
Add boiling water to raise mash to 149F for 45 min.
Remove 1/2 of liquid (about 1 gallon). Add to small kettle at 190F.
Add 1.5 gal of boiling water to raise mash to 162F for 30 min.
Remove most of the mash liquid (about 2 gal) to boil kettle and heat.
Add small kettle back to MLT to raise grain to 172F for 20 min.
Vorlauf and sparge with 190F water until gravity hits 1008.
It's not clear to me how I would integrate this into a batch sparge. Normally I use a spreadsheet to tell me how much water to add for the mashing step - it will produce 1/2 the mash liquid. Then I add an equivalent amount of liquid (to the runoff) and do a 2nd runoff. I just can't figure out how to make that work for this turbid mash schedule.
Any suggestions?
