The head distiller of Scotch whisky brand Laphroaig, Iain Henderson, retires from Allied Domecq, the brand's parent company, this month after a 30-year career in the industry. Henderson worked at 10 malt distilleries during his career and managed the distinct flavours of some of the world's most successful whisky brands, but he is best known for his tenure at Laphroaig.
