We all have our favorites. I'm generally a lover of 'dessert' flavors (coffee, cocoa, vanilla, cream, honey, baking spices).
That is not what this thread is about though!
This thread is about those flavors that send you running for the hills (or at least back to the humidor!)
For me personally there are two flavors that I really try to avoid:
1) Big black pepper
2) Damp soil/barnyard
I typically blame my general aversion to black pepper for being what really got me hooked on Habanos, as I get very little black pepper from Cuban tobacco.
What say you FOH? What are your LEAST favorite cigar flavors?
