Jim Murray writes that this HP has been distilled during one of the best periods of HP's recent history.
This is a very important assertion because :
distillers try to make people believe that their style of product never change, and of course it is not true, due to the change of barley type, malting process, yeasts used....
In the case of Highland Park I discovered this whisky in 1984 (12YO) and as far as I remember this malt was much more peaty and smoky than recent versions. When I tasted the on-line tasting HP I rediscovered the same impression (as far as my memory is reliable).
What about tastings of the same version of whiskies released in different years(Laphroaig 10Yo, Macallan 10Yo 100°proof,..)
