So on New Years eve I was going to brew 12.5 gallons of an Imp stout 1.105. I mashed in at 150. 30 minutes in, my 7 year old wakes up and is covered in hives head to toe. I turn off the burners and head to the Dr. 2.5 hrs later, I am back, no heated sparge water, nada. I turn the burners on high and start heating the sparge water. The mash temp was at 148. By the time I got the water heated the mash was like 3.5 hrs long. I skipped the MO to save time and started the sparge with 180 water. My daughter had more problems. I left with 20 gallons of fly sparge water going. When I made it back another 2hrs had elapsed. I had 20 gallons in the kettle. Post 120 min boil I had 17 gallons @ 1.087. I pitched a huge starter WY1450 that I had stepped 3 times with a total of 8 liters. Long and short, will it be too thin for an Imp Stout? Is body going to be my only issue? The gravity sample tasted great. Not sure if I over pitched. I had planned on the higher gravity at 12.5 gallons, not 17 gallons of 1.087. Craziest brew day I've ever had! Daughter is fine, determined she has developed a peanut allergy. Thanks
