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. Field monitoring conducted for the years 2011 and 2013 included soil sampling at strategic locations (figure 1), grape bunch and berry sampling for measuring bunch count, total weight and Brix (sugar) content in berry samples from the same specific sites for the two grape varieties (Chardonnay and Pinot Noir) planted in the vineyard. Unusually severe frost events were recorded in September 2012 in Kumeu, which affected the early developmental stages of the grapes significantly in many vineyards and this has resulted in observable decreases in productivity. Preliminary results show a substantial difference between the crops harvested for the studied years, which is an indication of the damage caused by the abnormally severe frost experienced in the region in the beginning of the growing season. It warrants further investigation to understand the influences of topographic features which are either protective or damaging to the vine, especially the young buds. The spatial analysis of topographic features, combined with plant production and soil nutrient composition identifies the damage prone areas. This information will be useful for any future investigations on possible mitigation strategies to protect vulnerable zones.
