How wsky1 thinks about whisky investment

Past auction prices are the most defensible signal of a bottle's collectable value — but they are not a forecast. The data below comes from 34+ hammered lots across six major auction houses; none of it is curated or pay-for-placement.

Three rules-of-thumb a working collector should keep in mind:

Liquidity matters. A bottle that trades once a year cannot be priced reliably. Filter for ≥3 observations before you trust any "median" number.
Premium swings. Major auction houses charge 24–28% buyer's premium on top of hammer. Net return after both buy- and sell-side premium is roughly hammer × 0.78 ÷ paid × 1.26.
Concentrated risk. One bottle is a story; a 6-bottle portfolio across two or three distilleries is an asset class.
