First Paragraph: This group is concerned with the physiology and biochemistry of grapevines as related to vine productivity and fruit/wine quality. In addition to questions of primary interest to students of vine growing, European members of this group are involved in parallel research activities which are funded by EU to provide a technical underpinning to decisions regarding acceptable methods of culture (limits on irrigation, cropping level, methods of training, etc.), factors which influence terroir, and models which predict the productivity potential of different climates (zonation, see notes below). In all that, of these are meant to define and regulate acceptable viticultural methodology in a manner which may be inconsistent with the American practice or viewpoint, the recommendations of this committees may be controversial.
