The Macallan, that liquid gold of a malt whisky, has entered the Guinness World Records book, as the most expensive whisky sold at auction. This is for The Macallan M Imperiale 6-litre Lalique decanter, sold at auction in Hong Kong early this year for a stunning $628,000. This breaks the previous record held by plain The Macallan in a Lalique Cire Perdue, going for just $460,000.
