It's all personal taste. I like non-tobacco flavorings in pipe tobacco blends to bring up and enhance the tobacco flavors. Tobacco-forward is one term for that. In MD, for me, the tobacco is just a carrier for the flavors. It's fun to sample, kind of like a flavored cola, but I wouldn't want a tin. I find that the flavorings that bring up tobacco leaf the best for me include alcoholic beverages like rum, whiskey, brandy, and liqueurs, and sometimes vanilla and fruit flavors like plum. Other food flavors, like chocolate and cocoa, I prefer in the foodstuffs themselves. But I don't want the flavorings to take over from the tobaccos themselves.
