Just brewed up my first 2.5 gallon batch of this last night. It is smelling good, and tasting great. It has a delicious roasted malt character to it right now, and I can definitely see how the vanilla and bourbon are going to complement this.
I'll be brewing up the second batch tonight. Too bad this darned recipe takes so freaking long to condition, I have a hard enough time waiting the 6 weeks for an average brew, let alone the 2-3 months needed for this one.
