(Decanter) - It's not all about tracing your lineage to the 14th Century. Jane Anson picks out the most exciting of Bordeaux's newcomers... 

I wrote a piece for Decanter last year on the spectator sport of tracking new winery openings in Napa.

Keeping up is pretty much a full-time job. From 2010 to 2014 alone, there were over 50 new wineries registering with the Napa Valley Vintners (NVV), from owners as diverse as NBA star Yao Ming to French billionaire François Pinault. A further dozen or so arrived during 2015 and 2016, and around 30 entirely new winery projects were approved by Napa County for planning permission (although some of these would be existing companies expanding or altering their facilities).
