Quick Water Requirements

WARNING: Mash tun capacity exceeded. Volume required: 14.16 gal (56.66 qt). Suggest reducing strike water volume to 10.29 gal (41.16 qt) and adding 2.16 gal (8.66 qt) sparge/top-off. 12.45 49.8  
WARNING: Based on your provided mash thickness (2.33 qt/lb), your strike volume will exceeds the total water needed for the recipe (11.92 g). Reduce mash thickness to 2.22 qt/lb or increase pre-boil volume to 9.53 g.

Notes

Very slow direct fire ramp from 146 to 160 over about 15 minutes. After about 15 mins at 160, pulled 2 gal THICK decoction and began to warm it. Ensured main mash stayed at 160 after decoction grain removal. Boiled decoction about 20 minutes and added slowly back to main mash.

2 gal thick pull is approx 30% decoction.
