It's usually good to get an Islay malt as a gift for a mate – these are the very peaty, fiery whiskies. Like licking Scotland – the iron fist to the velvet glove of some mainland malts. He'll probably love it, and if he doesn't you can just call him a fanny for not being man enough to drink a real whisky.
Popular Islay distilleries: Ardbeg, Lagavulin, Laphroaig, Caol Ila, Bowmore. This last one is a lot smoother then the others (to me).
Highland Park, distilled on Orkney, has been called the best all-rounder of the malts. This makes a nice gift and is available for a decent price most places.
