Time to Keg BFM v2

Today is the day for Black as Fucking Midnight version 2 to head to the keg for carbonation.  We brewed this one on December 26, 2011.  It was in primary ferment for about 2 weeks then moved to secondary for about 50 days.  I was waiting to kick the high test that was on draft...lol.  BFM v2 had an OG of 1.090 and finished with a disappointing 1.030.  This gives it about 8.5% ABV.  Don't know what happened here but I am thinking I may have to start aerating my worts better.  I put it under 20 PSI CO2 at about 37F.  Will leave it for 2 days or so and see how it carbs up.  Check out this link for the recipe.  Cheers!
