The whisky is sourced from an undisclosed Speyside distillery that still uses a rather old-school (and rather brilliant) bit of kit – a worm tub condenser. These classic bits of distilling equipment are made up of long copper coiled tubes housed in cold water in a large vat. You don't see too many of them around these days, with many distilleries having replaced them with more efficient shell and tube condensers. More efficient perhaps, but what is lost is the distinctive heavy, robust flavour profiles that can be achieved with a worm tub, and that are adored by distillers and whisky enthusiasts alike.
