INTRODUCTION The complex interactions of vine cultivars, and localised regional climate associated with specific vineyard sites are important attributes to the concept of terroir and significant contributors to grape maturity and wine sensory profiles. An improved understanding of the influence of each factor and their interactions is a challenging conundrum, and will enable more efficient production targeting specific wine styles. OBJECTIVES To characterise the metabolic flux of grape berries and resulting wines to characterise the relative impact of site specific climate, cultivar, and grape maturity based upon berry sugar accumulation models that consistently target specific wine styles. METHODS A spatial and temporal study of grape and wine composition was undertaken for two important cultivars in two distinct regions of New South Wales. Measures of composition and wine sensory ratings were simultaneously analysed using a multiblock algorithm taking advantage of the ANOVA framework to identify important contributions to wine style arising from grape maturity, vineyard site and cultivar. RESULTS A consistent flux of grape and wine constituents is evident for wine made from sequentially harvested grapes from the same vineyard with increasing levels of grape maturity. Contributions of region and vineyard site to wine style could also be elucidated. Differences in metabolite flux in grapes and resulting wines between cultivars growing in similar conditions are evident. CONCLUSIONS The combination of a metabolomics and multiblock data decomposition approach may be successfully used to profile and elucidate the contribution of abiotic factors to grape and wine composition and provide improved understanding of the terroir concept.

简介葡萄品种的复杂相互作用以及与特定葡萄园地点相关的局部区域气候是风土概念的重要属性，也是葡萄成熟度和葡萄酒感官特征的重要贡献者。对每个因素及其相互作用的影响的更好理解是一个具有挑战性的难题，并将使针对特定葡萄酒风格的生产更有效率。目的根据始终针对特定葡萄酒风格的浆果糖积累模型，表征葡萄浆果和所得葡萄酒的代谢通量，以表征特定地点的气候，品种和葡萄成熟度的相对影响。方法对新南威尔士州两个不同地区的两个重要品种进行了葡萄和葡萄酒成分的时空研究。利用ANOVA框架，利用多块算法同时分析成分和葡萄酒感官等级的指标，以识别出葡萄成熟度，葡萄园产地和品种对葡萄酒风格的重要贡献。结果从同一葡萄园按顺序收获的葡萄制成的葡萄酒中，随着葡萄成熟水平的提高，葡萄和葡萄酒成分的通量稳定。还可以阐明区域和葡萄园地点对葡萄酒风格的贡献。在相似条件下生长的葡萄品种之间的葡萄和产生的葡萄酒中代谢物通量的差异是明显的。
