Dr. Cornelius van Leeuwen has constructed an extensive overview on the topic of how 'terroir' impacts grape and wine aroma on a molecular basis and how those aromas are influenced by climate and soil. In other words, this article adds to the investigation and discussion on how place affects product..in this case, wine.
What is not objective or scientific about that?

Recent advancements in understanding the terroir effect on aromas in grapes and wines

FIGURE 2. OVERVIEW OF THE TERROIR EFFECT ON AROMAS IN GRAPES AND WINES.
Terroir expression is mainly mediated through (1) air temperature (climate), (2) radiation (climate), (3) vine nitrogen status (4) and vine water status which results from (A) soil water holding capacity (soil), (B) reference evapotranspiration (climate) and (C) rainfall (climate). These four components related to soil and climate impact aroma composition and expression in grapes and wines. By connecting recent advances in the understanding of the impact of environmental factors on aroma expression, wine typicity in relation to terroir can be better understood. |
