Abita makes a pecan beer as well. Althought it tastes more like a nut brown to me.
Well, pecan is a nut, so that sounds about right.
I'm not even sure what pecan, as a flavor, taste like.
FYI, (512) brewing makes a pecan porter. Only available in Austin,TX on tap.. I haven't tried it.
And I Shiner made a peach/pecan holiday beer. It's was sort of lame.
