[4] Glenmorangie, like all distilleries and breweries in Britain, suffered terribly between 1920 and 1950, with Prohibition and then the Great Depression in the United States reducing whisky sales.Development could have reduced the quality and quantity of water available to the distillery, so the decision was made to purchase around 600 acres (2.4 km2) of land around and including the Tarlogie Springs.According to Professor Paul Freathy, the director of the Institute of Retail Studies at the University of Stirling, "The French-sounding names are an unusual innovation, because what makes whisky unique is the traditional tie to Scotland.[15] The distillation process was for decades undertaken by a staff of 16, known as The Sixteen Men of Tain, who worked year round, with the exceptions of Christmas and periods of maintenance.Following acquisition by LVMH, Glenmorangie produced a rare limited edition aged in casks previously used to mature Château Margaux; these bottlings are now (2011) extremely hard to find and are priced accordingly.Glenmorangie have released a special edition bottling titled Cellar 13, which is from the warehouse closest to the sea, as the whisky is believed to have a distinctive flavour.Private Edition Range: (1st Annual Release) Sonnalta PX; 2010, (2) Finealta; 2011, (3) Artein; 2012, (4) Ealanta; 2013, (5) Companta; 2014, (6) Tùsail; 2015, (7) Milsean; 2016, (8) Bacalta; 2017, (9) Spios; 2018, and (10) Allta; 2019.[30] The 12-year Lasanta has been placed in the Top 10 percentile of all whiskies by Proof66.com, which aggregates liquor ratings from the San Francisco World Spirits Competition, Wine Enthusiast, and others.[31] Over the last five years Glenmorangie has won more "Gold Best in Class" awards than any other single malt Scotch whisky from the International Wine and Spirits Competition.
