The record
What happened, and when
A high level view of fifty-two years, compiled from the family archive and from documentary sources.
- 1941
Born
James Sneddon Swan is born on 25 December and grows up at Cockenzie and Port Seton, two working harbours on the coast east of Edinburgh. The boatyard there was building for the Admiralty and for customers abroad, from three yards by the end of the war, and the fishing fleet was fitting sonar and radar, which changed the catches. On the seafront the townspeople built the Pond Hall themselves, two and a half thousand neighbours raising the money and much of the labour over a couple of years, and what they put up had a ballroom, a library and a swimming pool with the highest diving board in Scotland. He grew up watching technical skill and ambition change what a place could be.
- 1965
Heriot-Watt, then Inveresk
Graduates in applied chemistry from Heriot-Watt University in Edinburgh, and joins a contract research laboratory a few miles along the coast at Musselburgh that autumn. It is not a whisky laboratory, and whisky is one client industry among many. He learns gas chromatography and sensory analysis at Inveresk, and learns as well how to put analytical science at the service of a business with a problem to solve, which is what he goes on doing for the next fifty years.
- 1968
Chill haze
Whisky clouds when it is chilled or watered. The cause of that chill haze is traced to the fermentation rather than to the cask. It threatened the export market, which J and B and Cutty Sark were leading, and answering it showed the industry what a laboratory could do for whisky.
- 1970 to 1974
Pentlands Scotch Whisky Research
A core of eight leave the Inveresk laboratory to set up a whisky research consortium of their own, on the strength of it. Four years of successful projects later it becomes a company, Pentlands Scotch Whisky Research Limited, incorporated on 30 September 1974, with twelve founding members: firms that compete with one another in the market and agree to fund research together at a point when whisky is carrying much of the country's export earnings. It works from premises at Slateford Road in Edinburgh, at the North British Distillery, and Jim Swan leads the programme covering maturation, quality, flavour and wood, which is one among several.
- 1979
The whisky flavour wheel
The whisky flavour wheel, a shared vocabulary for describing flavour, devised by Jim Swan and Sheila Burtles at Pentlands Scotch Whisky Research, working with the master blenders Paul Rickards of Robertson and Baxter and George Shortreed of Justerini and Brooks. It went out to the member companies, giving them one language for what they were tasting.
- The 1980s
Sherry casks and Jerez
The transport cask trade that had supplied Scotch whisky with sherry casks for a century is closing. He goes out to Jerez with Scottish blenders and coopers to find out whether casks can be made and filled to order instead. A research delegation follows in the spring of 1985, and the visits carry on for the rest of his career.
- 1986
Kentucky, Arkansas and Missouri
One of eight Scots sent to the United States to follow the other half of the supply: where the American oak that becomes so many Scottish casks actually grows, how it is coopered, and what bourbon does with the barrels before they ever reach Scotland.
- 1988
Doctorate
A PhD at Heriot-Watt University on wood extractives and the maturation of Scotch whisky.
- 1993
Glasgow and Missouri
Leaves Pentlands after nineteen years, at fifty-one, with no employer to go to. With his Pentlands colleague Harry Riffkin he buys a half share in R. R. Tatlock and Thomson, a Glasgow analytical firm founded in 1888 by Robert Rattray Tatlock, the city's Public Analyst. Riffkin took the chemistry as far as the spirit, and Jim Swan took everything after it, quality control and maturation. The same year he begins a research programme with the Independent Stave Company, a family cooperage at Lebanon, Missouri, which had been funding work on oak chemistry since 1990. That programme ran for the rest of his life.
- The mid-1990s
Whisky school
He delivers some of the first whisky schools at the Scotch Malt Whisky Society. The vocabulary his generation had built for blenders and trained panels is reworked for the new generation of single malt enthusiasts.
- From 1998
Hot climates
Works across the whole of production again, for distilleries in warm countries: the malt, the fermentation, where the cut falls, and how the casks are handled. Scottish practice does not transfer, and most of it has to be worked out from first principles.
- 2002
Consultancy
Sets up on his own, working directly for distilleries rather than for a research company or a cooperage. Relationships on the public record include Kilchoman, Penderyn, Kavalan, Amrut, Milk and Honey, Lindores Abbey, Spirit of Yorkshire and the Virginia Distillery Company.
- 2008
STR
Shave, toast, rechar. The STR cask gives a used wine cask a second working life, which matters most to a distillery with no maturing stock and no history to draw on.
- To 2017
Watching them grow
The last years are spent going back, and still learning. He mentors the people now running the distilleries he helped to start, tastes how the spirit is coming on, and shares in what they go on to win. By the end the map runs from Islay and Fife to Wales and Yorkshire, and on to Virginia, Taiwan, India and Israel. He was a Fellow of the Royal Society of Chemistry and of the Institute of Brewing and Distilling, and the Dr Jim Swan Award for Services to Scotch Whisky carries his name.
