To be honest I'm a bit of a phillistine when it comes to scotch, bit like wine really.
To be honest I couldn't tell a single malt from tescos own brand.
However I can tell laphroaig from other scotch whiskey on account that just the smell of it makes me want to throw up.
Having said that I did quite like the Royal Lochnagar that I had at the concord rally a couple of years ago and a bottle of co -op cheapy stuff that tasted pretty good after a few newcastle brown's.
