Winemakers around Australia have taken part in a tasting event using social media site Twitter. It was used to bring together wine lovers for what was called a 'Taste and Tweet' session. Using the common hashtag '#wcatt', tasting notes could be shared among drinkers in regions including the Coonawarra, Barossa, the Hunter Valley and beyond. Coonawarra winemaker Wayne Stebhens said it was a little challenging to describe the complexity of a wine with the 140-character limit Twitter imposes.
