The world’s top 10 most powerful fine wines4th February, 2013 by Patrick Schmitt
Liv-ex Power 100: Methodology
A list of all trades on the Liv-ex Fine Wine Exchange from the last year (August to August) were generated, and from that we identified a basket of 180 brands. These were then ranked in order of how much monetary value total trade had occurred on the exchange in the last year (Ranking 1).
Where the brand is a grower, we then identified a basket of their most famous wines, which we used for all subsequent calculations. We also identified the five most recent vintages for each wine available in the marketplace. For Bordeaux, the vintages used were 2006-2011. For other regions this was done on an individual basis.
We then calculated the average score from Robert Parker for each brand for the last five vintages available in the marketplace, and ranked them from highest to lowest (Ranking 2). Where no Parker score was available we used scores from The Wine Spectator. For Burgundy wines Allen Meadows’ (Burghound) scores were used.
We calculated the current average best price based on merchants’ price lists for each brand for the last five vintages (Ranking 3).
To measure performance, we calculated the average case price for each wine a year ago and compared it to its current price. We also modified the vintages used to ensure we were comparing like with like. The bigger the price increase, the higher the ranking (Ranking 4).
We then multiplied the current average price with an average production figure to get a production-weighted average price and ranked the brands according to this (Ranking 5).
Finally, we totalled up the rank number of each brand for all five components to get a score, the lower the score, the higher ranked the wine.
Where wines have the same score, the wine that scores better in the most categories is ranked higher.
