When smoking a cigar, it is important to pay attention to the taste and aroma of the smoke. As you continue to draw on the cigar, you may notice that the flavor begins to diminish or become more intense. If the flavor has noticeably changed or begun to dissipate, this could be an indication that your cigar is finished. If there are any signs of burning around the edges of the wrapper leaf, this means that your cigar has been over-smoked and should be discarded.
