You know, maybe I've been looking for the wrong thing all along. What I've been describing as "nutty" may not be a true taste of a nut, but rather the mellow, pure, "toasty" taste of the tobacco itself. For instance, I just smoked a bowl of 4noggins' Three Blind Moose, a blend with a distinctive butterscotch topping, but which gives me exactly the taste I've been looking for.
And many of the primarily Virginia blends also have that same quality, especially towards the end of the smoke.
Turns out I really am not all that fond of a "nut" taste, especially hazelnut, which I dislike with a passion, whether in tobacco, or coffee, or chocolate.
So I apologize for leading you all down the wrong track, but I'm glad I've been able to clarify what it is that I've been seeking. Thanks for all the suggestions and input. :worship:
