Glasgow 1770 White Port Cask Finish is a Scottish single malt whisky aged for 6 years and bottled at a robust 53.3% ABV. A finish in white Port cask is likely to add an extra layer of fruitiness and sweetness to the distillery's spirit.
For a novice drinker, expect a fuller, more assertive style because of the high strength, with cask finishing that may bring brighter wine-led notes alongside malt and oak. Adding a little water can help open it up and soften the alcohol.
