From his work at the National Institute of Agronomical Research near Angers, France, Gerard Barbeau concludes that wines made from the same kind of grapes, grown in the same region using identical practices but in slightly different terroir, harvested at exactly the same time, and made into wine in exactly the same ways, still can be remarkably different.

It would provide for on-going activities in a number of fields, such as agronomical research in producing countries, efforts to improve yield per tree and surface area in qualitative and quantitative terms, cost reduction and the expansion of consumption.
