ALLOA, Scotland | The noise is deafening at Diageo PLC's Abercrombie coppersmiths as skilled workers hammer away, molding 14 large bell-shaped stills destined for Scotland's first new whisky distillery in more than three decades.

A few miles down the road at Carsebridge, coopers are teaching the backbreaking traditional art of making oak casks to the first batch of apprentices in years as the company ramps up production to meet increasing demand from emerging markets such as China and India.

Clever marketing by Scotch distillers has encouraged a growing middle class in both those countries to use the prestige and heritage of the drink to reflect their newly affluent status. There is also a renewed appetite for the higher quality single-malt whisky from mature markets such as the United States.

Overseas sales of Scotch whisky rose 4 percent to an all-time high of $5 billion in 2006, the latest available figures -- equal to a whopping 25 percent of Britain's entire food and drink exports.

Industry experts say that strong growth continued through 2007 and into 2008, reversing a downturn in the drink's popularity at the end of the last century when its reputation as a tipple for the older gent saw it lose ground to white spirits like vodka and gin.

"Suddenly whisky is cool again," said Charles Allen, global brand director for Scotch whisky at Diageo, the maker of the world's two top brands by sales, Johnnie Walker and J&B.

Diageo is so sure that demand will continue to grow that it has unveiled plans to build a $80 million distillery at Roseisle in northeast Scotland, part of a $200 million expansion program that will see roughly $160.5 million spent on expanding capacity in distilling with the remainder dedicated to packaging and warehousing.

The whisky stills -- 15 foot-high kettles that separate the alcohol from the fermenting mix of water and malted barley -- being put together at Abercrombie will be moved into place later this year and the first production from Roseisle is slated for early next year.

Other producers are making similar moves -- some $1 billion of capital expenditure has been invested across the industry for 2008/09, according to the Scotch Whisky Association.

That funding is spread across Scotland, which has more than 60 old stone distilleries, such as Diageo's 200-year old Blair Athol stillhouse in the town of Pitlochry, dotted across its Highlands and rolling southern hills.

As domestic sales of Scotch whisky stagnate, 90 percent is now exported with state-of-the-art bottling plants feeding the product directly overseas from the eastern Scotland port of Grangemouth.

While there is continued growth in traditional markets such as the United States and Europe, emerging markets such as China and India are generating the most buzz, said David Williamson, the spokesman for the association.

"It is certainly advantageous that in two of the world's largest and fastest growing economies, whisky consumption is either a well-established tradition -- India -- or a marker of sophistication -- China," said Jason Holway, an independent analyst at Zenith International.

"An aspiration to 'trading up' and drinking scotch whisky in each culture should bode well for the future of the industry," he added.

Scotch Whisky sales in China have jumped from just $2 million in 2001 to $1.1 billion in 2006, aided by the east Asian country's decision to cut its spirits tariff to just 10 percent from 65 percent after it joined the World Trade Organization in late 2001.

Exports to India, where tariffs remain relatively high at 150 percent but well below their previous levels of up to 550 percent, were valued at $48 million in 2006, the most recent figures available.

Diageo's Johnnie Walker, the longtime market leader in the United States and the world's No. 1 brand by sales, is the clear winner so far thanks the company's strong marketing push in China to sell the tipple as the world's No. 1 party drink.

Sales of Johnnie Walker grew by 14 percent to more than 15 million cases last year, worth a total of $1 billion.

"We have been struggling to keep up with demand," said Donaghey.
