You might want to try some non-aromatic tobaccos that aren't Latakia or Perique blends either, to get a baseline
of what does not give you aftertaste. I agree, aftertaste is a deal breaker. You don't want it at all, and you don't
want it "with" your meals and beverages. Some of the plain Virginias, burley's, and non-aro Cavendishes might
be worth trying. Then you might experiment with mixing non-aftertaste tobaccos with others for a more complex
flavor. Just go easy, just one or two more at a time. Too many tend to give a hodge podge flavor. A home mix
of burley, Va, and Cavendish, in proportions to suit yourself, is often tasty. Good luck.
