Aberlour a'bunadh is a natural single cask strength malt whisky. Taken directly from specially selected sherry casks it is bottled as simply as possible without the use of modern filtering methods or the addition of water. The three main characteristics that distinguish Aberlour a'bunadh from the other single malts are: Original Cask Strength means that the whisky is bottled at the strength of the cask, which in the case of the first batch of a'bunadh is 59.6%. Not diluted, the whisky possesses a greater aromatic complexity. Most malts of the old days were cask strength. Not Chill-filtered. Today most malt whiskies are chill-filtered to prevent the whisky becoming cloudy when adding water or ice. This process, which did not exist in the 19th century, removes some richness and mouth feel as well as some fruit and sherry character. Aberlour a'bunadh is a true replica of the old days' malts. Only the best Sherry Butts, which previously held oloroso, have been selected by Douglas Cruickshank, Aberlour's Distillery Director. These casks are the rarest and the most precious used for whisky maturation. Again, they were used in the old days when sherry was imported from Spain in casks which were then left empty sitting in UK ports or ships. A 19th-century-style whisky matured exclusively in Spanish oak Oloroso sherry butts, then bottled at cask strength. Dark, luxurious and powerful; a superb after-dinner malt.
