Update: Averaged 34.5 in the first round of the National competition (didn't pass to 2nd round,...tough category). I agree with the comments, and will make this again with some minor changes.

It's overdue.
Batch #32
Rumination DIPA
--15lbs Scot. Golden Promise
--1lbs Crystal 15L
--36AAU Columbus 12%AA, pellets (60min)
--8AAU Centennial 8%AA, pellets (10min)
--8AAU Centennial 8%AA, pellets (0min, steeped for 5)
--2oz Centennial, dry hop
--WLP007 Dry English Ale yeast, 2L starter
OG: 1.071
FG: 1.020
ABV: ~6.7%
IBU: ~110
Mash in to 149F with 5gal (1.25qt/lb) for 60min. Mash out at 170F for 10min. Sparge water 180F, 1 gallon. Collected 6.25gallons of 1.067 wort for an efficiency of 71%. I added 1 tsp gypsum (calcium sulfate) in the mash water for two reasons: my water is really soft and the mash needs calcium, and sulfate accentuates bitterness.
I split the finishing hops from last time into two additions to add some complexity. And I have the right hops this time. And rumor has it, the right yeast. My gravity is a little lower than I expected for just over 5.25gal of finished wort...I probably overestimated the temperature correction when I calculated the mash gravity.
Dry hopped in keg while carbonating. FG is a little high, but it's crawling, so whatever. My stir plate broke (I dropped it), so the yeast population was lower than it should have been. Still tasty.

Ruin(ed?)ation
Updated 7/31/08 - Well, it's not Ruination. But it's pretty good anyway.

Five gallon mash tuns are a funny thing. They work great. They really do. So long as you're mashing less than about 14 pounds of grain. But when you want to mash 15.6 pounds for an OG of 1.075, your water to grain ratio quickly falls to almost one quart to a pound. The first lauter had a great SG of about 1.08, but I had to batch sparge twice to get the seven gallons needed for a 90 minute boil. My initial boil gravity came out to about 1.052. I added some corn sugar and DME to boost it a little bit and wound up with an OG of 1.065 after the boil. Even with the target FG of 1.010, this is going to be a little weaker in alcohol than we were shooting for. Between all of that mess and some hop substitutions, well, we'll see...
Batch #17
Stone Ruination Clone - "Rumination" (so Brad can say it right). Recipe from BYO's 150 Clones special issue.
--14.6 lbs 2-row
--1 lb Crystal 15L
*--8 oz Corn Sugar
*--1 cup Light DME
--36 AAU Magnum (60min); *I used 4 oz of 9.3% Newport
--15.7 AAU Centennial (Steep 5min at flame out); *2oz 6% Cascade pellets + 1oz 7.4% Cascade whole
--2 oz Centennial (Secondary 3-5 days); *2 oz Cascade
--Whirlfloc (20min)
OG: 1.065 [1.075 target]
FG: 1.008 [1.010 target]
ABV: 7.1% [7.7% target]
IBU: ~120 [100+ target]
*My subs and fixes
Mash grains at 149°F for 60 minutes, 90 minute boil. My mash was funky because of the capacity of my mash tun. I extracted 1 gallon after an hour, and pulled out 6 more over the next hour. I had lots of temperature fluxuation due to heat loss out the top (no tight seal when it's that full) and hot water additions combined with difficulty stirring such a thick mash. Moral of the story: 10 gallon mash tun for OGs over about 1.065. Racked to secondary after 8 days. Cascade added. Kegged after 5 days.
