Sauvignon blanc is the varietal that awoke the world to New Zealand wine and continues to dazzle wine critics across the globe.

Friday 16 May 2014 marks the fifth annual International Sauvignon Blanc Day – an online initiative that started in California with St Supery Winery as a global social media wine tasting.

The event gets bigger every year and New Zealand Winegrowers is now involved to ensure the country's wine is well represented.

Celebrations kick off in New Zealand, the home of sauvignon blanc, and makes its way around the globe.

Appreciation and admiration of the grape follows the sun with sauvignon blanc lunches, tastings and events taking place in Melbourne, Hong Kong, London, and Toronto, finishing 43 hours later at Twitter Headquarters in San Francisco.
