It's doubtful that any other distillery will come up with a whisky that tastes like Gilpin Family Whisky because of its secret ingredient: urine. Researcher and designer James Gilpin uses the sugar rich urine of elderly diabetics to make his high-end single malt whisky
. From the article: "The source material is acquired from elderly volunteers, including Gilpin's own grandmother, Patricia. The urine is purified in the same way as mains water is purified, with the sugar molecules removed and added to the mash stock to accelerate the whisky's fermentation process. Traditionally, that sugar would be made from the starches in the mash."
