What drives this bottle's value

  • Age statement

    A 18-year age statement signals extended maturation, which limits how much was ever bottled.

  • Named / limited release

    Released as caskstrength, a named edition rather than part of the standard core range.

These are scarcity and demand signals drawn from the bottle's own attributes — they describe the bottle, not a prediction of future price. Not investment advice.
