I'm going to think on this one ... but I would say that Whiskey is VERY expensive in Spain ( if you want to buy a good single malt or even a bourbon ) . I can often find similar in the UK for nearly half the price and yet alcohol is hugely taxed here in the UK . So if you have a whiskey drinker amongst your friends , and you live in North America I would suggest that a bottle of good bourbon would be an excellent American gift . I've been to The States and Canada many many times but only really bought wine in USA . I wonder whether in USA they do the same as in Canada and sell liquor in lightweight plastic bottles ? Such a great idea I think .. and perfect if you're travelling .
