Ive been wondering this for a while now. I have never really experienced a great taste change in a cigar towards the end (been smoking for about 5 years....2 if you are going to prosecute me for underage smoking)...until tonight. I had a CAO Cameroon Toro, which Ive had many times, and the taste changed a lot towards the end. I could be wrong, but Ive always been under the assumption that the same blend is used throughout the cigar....if thats true, then what causes the change? Buildup of oils? The heat?
