Okay, gents, here we go.
I am brewing my attempt at Arrogant Bastard on 3/29. I have a 3.5L starter of WLP007 going right now, which I will step up again with another 3.5L on Friday, after work.
I am going off my previous attempt at this, and the work put into this "clone" by Stonebrewer, Ultravista and TrickyDick.
As noted by the others, and which is my personal opinion as well, Special B is off in this recipe. However, it isn't that far off. Special B has a raisin/date flavor to it which is just a little "over-the-top". C120 and C150 get you close on color, but lack the flavor profile. So, I got to thinking.... I know, dangerous!
What grains follow closely in Special B's footsteps. Rather, what grains were created to meet the needs of brewers who didn't have access to Special B. Well, there were two that caught my attention.. Weyermann CaraAroma and British (Munton/Baird) Dark Crystal.
Well, Stonebrewer already tried the British Crystal and thought it was close, but still not quite right. So, I am going for CaraAroma. CaraAroma has a less sharp dark fruit (plum/raising/fig) flavor, has a more pronounced aroma profile, and is reported to be a little more "roastiness". I have also heard that CaraAroma has a tendency to provide more red color than just contributing to darkness.
As such, here is what I am doing:
