A couple of months ago I was in Geneva Switzerland at Gerard Cigars, I bought a couple of Vintage Habanos. Started to smoke a Saint Luis Rey Churchill, great white ash, straight burn, I was very proud of the long ash this great Cigar was producing. All of a sudden the same persona that sold me this great Habano, told me that leaving the Ash in exchange for the Instagram Picture was a great mistake. Since according to him, the Long Ash changes the taste and flavor of any Habano. According to him, only 1-2 inches should be allowed in order to have the pure taste of the Habano.
So last night a couple of friends and myself were smoking cigars, and they were competing for longest cigar ash, I told them about the advice I received from one of the employees of Gerard Cigars, but basically they blew me off and said it was complete nonsense.
Would appreciate fellow Habanos Smokers comments, since there has to be some Science behind this theories.
