Alfred Giraud's Harmonie blends together three French malt whiskies from different distilleries. The whisky has been aged in both new French Limousin oak and American white oak casks which previously held XO Cognac, and after this ageing it's then blended with a fourth French malt, though this one is lightly peated. This final liquid goes back into the Cognac casks for further ageing, and then it's bottled at 46.1% ABV.
