‘Wine Grenade’ may have explosive effect on industry

A year on from winning the University of Auckland’s Dragon’s Den-style business competition, a wine industry start-up’s “grenade” is already in commercial trials with a major Hawke’s Bay winery. Wine Grenade, a micro-oxygenation tool that removes the cost and complexity associated with maturing wine, won the Spark $100k Challenge in 2014 and has now been named as a finalist in the New Zealand Innovators Awards.
