Single vintage
Distilled in a single year (1988), so the available batch is inherently finite.
Considerable age
A 30-year age statement reflects long maturation and the small surviving volume that implies — older stock is scarcer.
Single cask
A single-cask bottling (cask 9x149) comes from one strictly limited outturn rather than a large batch.
Independent bottling
An independent bottling by smws, 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.
