Single vintage
Distilled in a single year (1990), so the available batch is inherently finite.

A 24-year age statement signals extended maturation, which limits how much was ever bottled.
Independent bottling
An independent bottling by signatory, typically produced in far smaller numbers than an official distillery release.
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.
