Macallan 1824 Blue Label Estate Reserve Using high-aged Spanish sherry barrels and American sherry barrels, in addition to the chief bartender carefully setting the optimal original liquor strength of 45.7%, it also uses non-condensing filtration to retain the rich esters in the liquor, allowing the whiskey to have a better flavor. Macallan Brand Description Founded in 1824, Macallan is the benchmark for whiskey in recent years, especially for the wines bottled before 2004. It insists on bottling only the original liquor of the first barrel, and uses 100% aged sherry barrel original liquor, so the wine color is very deep and rich in fruity aroma
