I feel it is more of a attribute more than a detriment itself as far as the topic goes.I believe that every spirit shows it's nuances in quite different ways especially with the way evaporation of alcohol/methanol as in part towards the finish whether it be difference between proof or level of char within the barrel all show differently.To me the finish is one of the key factors in enjoyment and without this the true spirit of one's chosen pour would be greatly effected or even lost.
