Age statement
A 18-year age statement signals extended maturation, which limits how much was ever bottled.
Non-standard format
Bottled in a 500ml format rather than the standard 700ml, which sets it apart from the regular run.
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.
