Thompson Bros. Glen Elgin is a Speyside single malt Scotch whisky bottled from a single refill hogshead at 22 years old. A refill cask typically allows more of the distillery character to show, with oak influence tending to be more restrained than in a more active cask.
At 52.2% ABV, this is likely to offer a fuller, more concentrated presentation than a standard bottling. For a novice drinker, expect a mature single malt style where age and a long refill-maturation may highlight balance, texture, and subtle complexity rather than heavy sweetness or strong smoke.
