What Makes a Wine 'Fine' — and Investment

The concept of 'fine wine' is not an official category but a functional measure of market value, ageing potential, and consensus among critics and merchants. The parameters are: grape and terroir of exceptional potential (e.g. Romanée-Conti, Pétrus, Sassicaia), limited volume, documented decades of ageing potential, and a secondary-market price exceeding the primary. Wine investment requires understanding provenance, storage, and fluctuations on platforms like Liv-ex. Specific vintages matter greatly — a great year such as 2010 or 2015 in Bordeaux dramatically lifts platform values. Critics' scores (e.g. Wine Advocate and Vinous) influence prices but are not the sole measure of quality.
