Nice, but it didn't quite turn out what I was trying to achieve. It's not malty enough and too roasty.

Notes
1.012@137 preboil reading. Not sure if that's accurate ... now.
Added .5lb XLDME to 8.5gal to make sure to hit target gravity.
Yet gravity came in too high @ 1.040 instead of 1.037. So the dme was not needed.

6/9 - 16:00 48 hrs later, still no activity. But beer in hydrometer tube started to ferment. Began heating pad to get the temp up to 72F
Active fermentation by bed time, dropped temp back to 70F.
Then 69F the next morning.

6/15 - 1.011

6/17 - Racked to secondary - 65F

I found in the next brew session that the glass thermometer and the digital vary by 2-3 degrees; the glass being higher.
I used the glass one solely on this one.

Next time take gravity readings closer to 100-120F.
Drop the roasted barley and just use the pale choc (maybe .33lb), hit and hold 158 mash, with a thicker mash. If still not malty enough then add carapils.
