How are the indices calculated?

Calculating the Cult Wines Indices.

Our indices track the prices of the most searched for wines in Wine Searcher's database. These price points are based off calculations used to determine the market price of any given wine, based on the spread of offers available for them on Wine Searcher. 

From the c. 100k individual wines (LWIN 11s) we review, we filter the data to ensure that the universe of wines we're measuring represent a market that is truly tradeable.
