Climate effects on grape production and quality at Kumeu, New Zealand (original) (raw)

2013, 20th International Congress on Modelling and Simulation.

Grape quality and anticipated berry composition (Brix, flavour and aroma) significantly vary due to the variability in seasonal climatic and environmental conditions, such as soil and topography within vineyards. Such "Meso" climatic and "terroir" variations affect grapevine phenology (from bud formation to berry ripening stages). This in turn affects productivity, some instances extensively, in terms of total vine yield, grape bunch count, berry weight and composition even within a vineyard. Quantifying these effects on grape production and quality has been a challenging task as no detailed study has been performed at precision agricultural level for this vineyard located in Kumeu, New Zealand. This study investigates the influences of climate and soil components on the production of this vineyard using data gathered from 2011 to 2013.
