(InfoWine) - Sauvignon blanc is probably the world's most thoroughly researched grape variety. For the last few years, scientists in New Zealand, France and Australia have been busy working on the science of Sauvignon. What are the key aroma and flavour molecules in Sauvignon blanc wines? And what is it that makes Sauvignon blanc from New Zealand's Marlborough region so distinctive? To answer questions such as these requires a multidisciplinary approach, bringing together chemists, plant biologists, molecular biologists and sensory scientists. New Zealand in particular has invested a lot of money in attempting to understand the roles of terroir, viticulture and winemaking on the way that Sauvignon blanc wines taste.
