This limited edition Bushmills Irish whiskey is one out of 10 bottles in their highly sought after Causeway Collection. The Causeway Collection is a series of cask-finished single malt whiskies. The range is inspired by the Giant’s Causeway, a large formation of hexagonal rocks in County Antrim, Northern Ireland. This vintage 2010 single malt matured in oloroso and bourbon casks and was finished in cognac casks. It’s bottled at 46% ABV, slightly higher than their regular 1o-year-old expression.
