With 20 million casks lying in storage maturing, Scotch whisky looks set to hold its strong place in the world market for decades to come. It's the third biggest industry in Scotland, contributing £3.3 billion to the economy per year. But the landscape is changing - both within Scotland and across the UK. Recent years have seen dozens of new distilleries opening in Scotland and also in Wales, Northern Ireland and England. Sheila Dillon celebrates 'Whisky Britannia' to discover who exactly is choosing to start distilling whisky, how you perfect your craft and flavour and become distinctive in such a busy marketplace. Do these new brands have anything to offer which the established companies haven't tried?

Reporter and whisky lover Rachel McCormack also uncovers the secrets of perfecting a blend, and trying to please a foreign market who may also mix it with coconut or green tea. Whisky writer and expert Dave Broom shares some of the extraordinary things he's seen but warns many markets from Iceland to Japan are keen to get a taste of the action too.
