Exports of Scotch Whisky broke the £2 billion barrier for the tenth successive year in 2002, which was also its third best performance ever, according to figures released by The Scotch Whisky Association (SWA) yesterday.  Nearly £2.3 billion worth of whisky was shipped to 200 countries, however "global economic difficulties" did have a knock-on effect on the volume of exports, which fell by 6.9% to 943.4m bottles. In the UK, Scotch held firm overall at 9.5m cases assisted, the SWA said, by five years of duty freezes that have brought stability to the market.
