Roasted Barley ground into finest dust possible via coffee burr grinder and added at end of mash, recirculated for 15 minutes (vorlauf) before lautering into boil kettle. I brew on a 3 vessel system but do full volume mashes, recirculating through a herms coil in my HLT. Electric brewing on 240v system with 5500w elements.
OG recipe: Maris otter pale: 7 lbs, flaked barley 2 lbs, roast barley 1 lb.
Revised recipe now includes a small charge (5 oz) of chocolate malt to increase coffee flavors.

brewed again 7/26. modified chocolate rye to 8 oz and ground it up with the roast malt for a late addition (added it 15 min before lautering) Mash 148. i always get better efficiency with this beer than others, so i added some water to drop my pre-boil gravity down to 1.038, and added more water at the 15 minute mark to reduce from 1.047 to 1.044 approx, which is about 2 points from what i finished at. pitched 66f
