The Macallan single malt whisky is produced in the Speyside region of Scotland using Golden Promise barley. It is aged in bourbon and sherry casks. The distillery was founded in 1824 by Alexander Reid and is located on the banks of the Spey River. The production process involves malting, milling, mashing, fermentation, and distillation, with only the heart of the run being collected. The whisky is then aged for a minimum of 10-30 years in various oak casks. Tasting notes describe the whiskies as having flavors of dried fruits, nuts, vanilla, and hints of orange.
