(Guardian) - Wine prices set to rise after poor grape harvest, warns Majestic boss. Wine lovers are facing a worse than usual new year hangover as poor harvests in some of the world's most important wine producing regions threaten price hikes of up to £1 a bottle in 2013. Majestic Wine boss Steve Lewis said the increases would be most noticeable in the supermarket where British favourites such as Italian pinot grigio, New Zealand sauvignon blanc and Australian chardonnay sell for around £5 per bottle.
