Old Particular Bunnahabhain is a single cask expression released under the Old Particular label by Douglas Laing & Co., one of Scotland's most respected independent bottlers. Douglas Laing was founded in 1948 and has built a strong reputation over decades for selecting exceptional casks from distilleries across Scotland. The Old Particular range represents their premium tier of single cask, single malt and single grain releases, each chosen for their individual character and quality. Bunnahabhain, the distillery behind this expression, is located on the Isle of Islay and is renowned for producing a distinctly gentler, more maritime style compared to many of its peat-heavy island neighbours. When bottled under the Old Particular label, these single cask releases showcase the natural character of Bunnahabhain with minimal intervention, typically presented at natural cask strength without chill-filtration or artificial colouring. The 18 Years expression highlighted in this range was released as part of a commemorative bottling marking Douglas Laing's 75th anniversary. The Old Particular series is highly regarded among whisky collectors and enthusiasts for its transparency, quality selection and the diversity of distilleries represented. Releases like this Bunnahabhain 18 Years demonstrate the range's commitment to celebrating Scotland's whisky heritage through carefully curated, limited single cask expressions.
