Glenfiddich, although rather commercialised, is a lovely light malt.
It's typica lof the East coast malts, and a sniff, then a mouthful of the neat stuff, followed by a drop of water in the rest of the glass, will be a good intro.
I prefer the West coast malts - Ardbeg or Laphroaig are favourites. They're big hearty drinks, full of peat and cough mixture.
The thing is, enjoy it. If you want your whisky over ice cubes.or with ginger beer - enjoy it!!
