Hoping to make a stab at Firestone Walker's Anniversary Ale

[Ted123]

Hello all,

I'm trying to come up with a recipe for the Firestone Anniversary Ale . . . I know it changes every year, and that it is a blend of a number of their ales (some brewed just for blending) . . . but what the Anniv. Ale always seems to have is an amazing silky oakiness/vanilla-ness, and sort of a hybrid between a Wee Heavy, an Imperial Stout, and a Barley Wine . . .
Any directions to point me in?

Thanks much--Ted
