Notes

Mashed in with 5.5 gallons of 160 degree water into 14 lbs of maris otter.
Collected about 4.15 gallons from first runnings, all from maris otter.
Added specialty grains and 4.5 gallons of 180 degree water and let sit for 10 minutes, then collected 3.5 gallons. About 7.65 gallons going into boil.

After boil was completed I noticed I had extra wort that had dripped into the mash tun from the BIAB, a little over a gallon I think. Tested it on the refractometer and it still had plenty of sugar in it, reading at about 16 brix. So I boiled this for 20 minutes, cooled it then added to fermentor. Then dumped out some wort to get back to 5.75 gallons. This increased the gravity by about 3 or 4 tenths.

Rehydrated 3 packs of Safale 04, cooled to about 66 degrees then pitched into 54 degree wort and stirred vigorously. Had to move upstairs because temp was at very low end of fermentation range.

Actual OG 10.090
FG 10.018

Split batch after 3 weeks by racking 3 gallons on 24 ounces of frozen raspberries. Racked the rest into secondary with no additions.
