From bottles found found in Antarctica in 2007 from Shackleton's 1909 South Polar expedition.

"Phenol and related phenolic compounds show up in Scotch whiskies, giving them the unmistakable character that's referred to "peaty," because the flavor is introduced when the grain is exposed to peat smoke during the malting process. Chemical analysis revealed not only the quantity of phenolics in the Mackinlay -- surprisingly low, given that era's reputation for heavily peated malts -- but also the particular balance of compounds, which enabled the experts to pinpoint what region the peat used had likely come from. The answer? Orkney.

"Similarly, analysis of the compounds that result from barrel-aging was able to finger the barrels in which the whisky was aged as ones made from American oak and probably used once before to age wine or sherry. Gas chromatograph olfactometry, in which the spirit is broken down into its volatile components and each of these smelled individually by experts, gave clues as to details of the fermentation and distilling process."
