This is a single malt whisky bottled at a high natural strength of 57.7% ABV from a single cask. That usually means a more concentrated style, with each release showing the character of one individual barrel rather than a large batch.
The Fino Sherry label suggests influence from a cask associated with fino-style sherry, which is often linked with a drier, nuttier profile than richer sweet sherry styles. For a new drinker, expect a robust whisky that may open up with a little water.
