Cranium Crusher Scotch Ale Brew Session

We did this as part of a partigyle batch. Heated a total of 8 gallons to split between two igloo mashtuns (4 gallons per mash tun). mashed in 13.2 lbs of grain in each mash tun. Overshot target temp of 150, settled in at 152.2. Steeped the specialty grains separately with 6 qts of water @ 150 & rinsed with 4 qts of water. Wound up with more runoff than anticipated (nearly 7 gallons instead of 6.5) so we did a 90 minute boil instead of planned 60. In the end OG still came in close to target. Carbonation level is quite low considering I measured out too much corn sugar on bottling day. I wound up using about .5 oz more than I needed. First pour was still. No carbonation at all. I have since resorted to turning the bottles upside down and agitating the beer moderately in order to achieve a level of carbonation.
