Research paper thumbnail of Wine Typicality and Vine Responses to Terroir Constraints, A Review

This study reviews the terroir effect on vine physiology and grape chemistry and sheds light on the possible consequences on wine typicality. The terroir expression is optimal when vine precocity matches with local climatic conditions and when yield and vigour are limited through water deficit stress or low nitrogen availability. However, even if environmental factors do affect the composition of vines and grapes, there is no scientific argument that proves a terroir effect through any sensory marker in wine so far. Recently, promising studies have shown interesting results that bond microbiological and mineral footprint to taste and scent in wine. Further research is necessary to correlate terroir effect to wine typicality.
