Quick Water Requirements

WARNING: Mash tun capacity exceeded. Volume required: 12.31 gal (49.24 qt). Suggest reducing strike water volume to 10.7 gal (42.8 qt) and adding 0.31 gal (1.24 qt) sparge/top-off. 11.01 44  
WARNING: Based on your provided mash thickness (2.71 qt/lb), your strike volume will exceeds the total water needed for the recipe (10.78 g). Reduce mash thickness to 2.64 qt/lb or increase pre-boil volume to 8.73 g.

Notes

Added two tabs NaMBS to strike water not shown in water chemistry. Pulled decoction to a side kettle a few minutes after full mash reached 160*. Pitched 3 packs WLP833 for 500-600b cells and one pack S189 for extra attenuative properties. BF projects a final gravity if 3.1P, but this beer usually finishes at 1.016 to 1.020.

No Sparge, full volume mash with recirculation during mashout.

Jan-2023 batch: 2023 Indiana Brewers Cup - Bronze (19 Entries). My doppelbock with a very similar grist/process won gold.
