Highland Park 15 Years Old is a distinctive and rare expression from Highland Park, known for its unique combination of gentle peat and the influence of Oloroso sherry casks. This particular single malt whisky has an interesting history. It was initially introduced in 2003 as a travel retail exclusive but quickly gained popularity among whisky enthusiasts. Due to its success, it was later included in the distillery's core range.

However, in 2016, Highland Park decided to discontinue the 15-year-old expression. Fortunately, it made a triumphant return in 2021 under the name "Viking Heart." This whisky offers a smooth and highly enjoyable drinking experience, making it a favorite among those who appreciate the Highland Park style.
