I am still working on dialing my efficiency and was looking for something kickass to try--so I came across this thread.
Did the 6 gallon batch as noted by OP. Given the amount of hops...thought I would try and shoot for a pre-boil of 8 gallons of wort. Happy to report, I did get my 6 gallons into the bucket I was shooting for, but missed the gravity.
Was shooting for 1.065, but got 1.054 (like I said, still working on my effeciency). I also took a pre-boil reading and got 1.050?? Instead of the 11.25 of 2 row mentioned, I did round up to 12 lbs. Remaining specialty grains remained the same.
Mashed at 154/153 for 1 hour.
Followed the hop additions as noted.
I'm sure it will still come at pretty awesome, so I am happy about that. I had a taste of the pre-boil sample...nice taste..had a taste of the post-boil...wowzers...very bitter
I am looking forward to seeing how this all shakes out
Edit: Forgot to mention---15 mins left of boiling time and I ran out of propane! I moved inside the kitchen and tried not to skip a beat...I'm guessing this bump in the road may have contributed to me missing my OG as I didn't tack on extra time....lesson learned.
