The prevailing notion is that grain whisky needs to be old to be good. But might that also be because most grain whisky probably doesn't mature in the best casks? This Strathclyde received a finish in a very active sherry cask, making it a highly enjoyable whisky.
To be honest, I'm not particularly fond of grain whiskies. Yes, there are some delicious examples, but generally speaking the flavour profile of grain whiskies is very narrow, offering not nearly the amount of diversity you'll find in single malts.
