On my less than pleasant experience with the Tactical ( Talisker) single cask bottleing I have come to the following conclusion.
In most, if not all, of the older expressions that i have tasted - anything from 20y and older there was always that lurking, in the shadows "dark side" of that particular distillery, something that I could never really place, either in the smell, taste or after-taste, but always somthing that made me want to go back and try and pin down that ellusive element.
So now I think that its these "special" casks, and their spesifc impact on the vatted malts, that bring this dark character to the expression. Its like there is good and bad in all of us, and under different circumstances different elements show up. In my case, i think i have pinned down the Darth Vadar of Talisker, and it lives in this bottel of 23y old OMC Tactical!!
Or maybe i just had one to many this evening...
