Obsidian Stout

With summer coming and the weather getting cold, I thought a nice mid ABV Stout on Guinness Gas would be great.  Plus my wife loves them.  This is from the Brewing Network's "Can you Brew it?" show.

This was the 6th generation of WLP001. Brewed with the 2nd trial of Fargo Session Pale. This is the recipe from, "You can brew it" on the Brewing Network.  Planning to Ferment at 65 for 4 days then let it ramp up to 71 degrees.

Update #1

I have to say, this beer was brewed for my wife who loves the roasted notes that go along with a good stout or even a porter.   This has now been on tap for over 2 weeks and the beer is very clean with a mocha colored head.  I am looking for the original clone beer to compare but I am having trouble locating one.  Taste, color and clarity are top notch.
