Notes

The plan is to barrel-age half the batch in a used Balcones whiskey barrel. The other half I will begin to lager. I can use this second half to blend back with the barrel-aged half to desired level of barrel flavor. Then both halves will finish lagering. Also using Gordon Strong's "late addition mashing." I'm only putting the base malts (pilsner and munich) in the full mash time and will stir in the dark and caramel malts right before sparging. The goal is to keep the mash ph at the right spot without a lot of mineral additions. I chickened out on the amount of chalk to add. The water calculation called for 34 g of chalk which I was going to split between the mash and sparge water. I decided to just add the 17 g to the mash water. This was dissolved in a liter of carbonated, filtered water (perKai Troester's page http://braukaiser.com/wiki/index.php?title=Building_brewing_water_with_dissolved_chalk). If the chalk was 100% dissolved I'd only need half anyway. Originally based on Jamil's Zek's Porter
