Walnut, to me, is an extremely mild English like taste. I find the Carter Hall adds a bit more to the Burley and the Virgina also comes tru. With my crazy mix, I can taste the nutty like Burley and spicy virgina along with just a faint hint of Latakia. The 2 blends just seem to go together and burn perfectly as well. I like to add a bit of Storm Front sometimes to give it just a bit of a smokey flavour.
I have been, for quite some time now, trying to find my 5 favorite tobaccos so as to stock up (at least 10yrs supply)in case it becomes more difficult to ship to Canada in the future. My tops so far are: Carter Hall, Walnut, Storm Front, MacBarrens Mixture(Scottish Blend), 1792 Flake, HH Old Darkfired, A little Penzance, and a very few others.
My theory is that I can smoke Carter Hall, Walnut and Storm Front each by themselves or mix to different ratio's for different tastes or moods. The others are just baccy's that I like to have once in awhile, but wouldn't miss too much if I couldn't get them. I can easily store 10 yrs supply of the top 3 baccys in a very small area and at a very cheap price. Most days I crave nothing but the Old Codger baccys, but I will continue to have a few tins of some others for that "Once in a while" smoke.
