Dogfish Head made that brown ale (Raison D'Etre-esque) which was boiled and aged with cedar wood.
Pignoli nuts would blend with pine, cause it's from the pine cones, but pignoli is such a sublte flavor even when toasted and pine resins are devious. Unsalted and roasted walnuts and pecans have a stronger taste compared to the other nuts. It's going to be gentle balance.
