This is a long-aged single-cask rum bottling from Guyana, distilled in 1999 and released in 2021 at 43.2% ABV. The Uitvlugt and Port Mourant names point to well-known Demerara rum heritage rather than a whisky style.
For a novice drinker, expect a mature, oak-influenced spirit with the depth that can come from extended aging and single-cask release. The refill oak cask suggests the wood may support the spirit rather than dominate it.
