Just gonna chime in and say this recipe is a winner. Brewed the winter solstice back in mid October, and enjoying it now. I used S-05 and fermented in the low 60's, nice and clean with pronounced caramel notes. I used 0.75oz of pure vanilla extract at bottling.
Its very close to the real thing...certainly better than the kit offered by Austin Homebrew, which I tried last year and is not even in the ballpark.
