MEN WHAT TAKE THEIR WHISKEY STRAIGHT (the men are not mods).
Mods drink Whisky (not Whiskey), and of course it's straight single malt.
Depends - Whiskey, such as Irish Whiskey, and I will use this for the sake of the example, is tripled distilled, and can made from a single malt, single grain, blended or a pure pot still. It has a smooth taste, which has a slight spicy hint to it.
Whisky, such as Scotch Whisky has a smokey flavour to it, due to the method in which it is distilled, offering a unique taste.
The main difference is actually in the distilling methods used. I could go deeper into an proper explanation, but I'm in work at 6am for a training day....Cue muttering and grumbling as I travel tomorrow. (Oh, and btw, I worked in a major distillery for about two years...and before anyone asks, yes, I did get free stock.)
