Many offerings at Sotheby's upcoming Distillers One of One auction are extremely rare, with The Scotch Malt Whisky Society's The Only Drop exceedingly so. The Speyside-distilled spirit inside was initially placed in an Oloroso sherry butt on 25th September 1989. In May 2019, the liquid was equally divided between first-fill Oloroso and first-fill Pedro Ximénez hogsheads. They were mixed together three years later, resulting in The Only Drop. Bottled at 50.8% abv, it's surrounded by a paper pulp sculpture made using wood shavings from the original casks, and comes with a 10cl miniature bottle for tasting, better to preserve the one-of-a-kind original. It will come up for auction on October 5.
