How can a spirit mature with age. Wine, yes, I understand..but spirit no. Paul is right, this is all about marketing. Blended whisky even were it 100 years old will always be inferior to Malt. Now although I do not drink the stuff myself, I would also say that an Irishman would argue in favour of Whiskey.
To my whisky drinking man (and he has impeccable taste as he lives with me!!!!! Who knows maybe that's why he drink it in the first place), ther's not whisky like Scotch Whisky BUT he is very fond of Burbon, and Canadian Club. To his taste, the two are totally different to Whisky. Ultimately, its all down to taste, isn't it?
