Erm - Grant's blended Scotch whisky is distilled in Girvan in Scotland, and has no relationship to General Grant of American Civil War fame. In fact, he was dead before the distillery was operating.
I'm not supposed to drink alcohol yet, but I have tasted the single-malt Glenfiddich my dad drinks and I quite liked it. But my dad says blended scotch, like Grant's are rubbish, and only fit for mixing with soda. He also says a traditional Scots whisky drinker will never mix his single-malt with anything, nor will he pollute it with ice.
