Here's the latest instalment of our monthly series on biggest Brand gainers.

The latest Wine-Searcher search frequency data is in, allowing us to update our Brand scores with changes to each wine's popularity (one of the two criteria contributing to the Wine Lister Brand score, the other being a wine's presence in the world's top restaurants).

The chart below gives us a breakdown of the five wines which improved their Wine Lister Brand score most during December:

The top five Brand gainers are not concentrated in any one country or region, with Italy, Australia, and three different French regions all represented.

As in November, Barolo is again represented.  With a percentage increase of 28% in Brand score, Marengo's Barolo Bricco Viole saw a surge in monthly online searches, increasing from an average of 103 to 342.

The second biggest gainer is Magnien's Charmes-Chambertin Grand Cru, whose average monthly searches have doubled, helping raise its overall Brand score above the Wine Lister average to 545/1000.

We'll be back next month with an update on January's biggest Brand changers.
