Aroma Compounds of Grape and Wine

Abstract

Aroma compounds represent the most important factors that play a crucial role in the formation of wine character. Generally, wine’s aroma depends on the grape variety, the winemaking process and environmental factors, such as soil, weather, water, sunlight etc. Here we present a short review of the types of volatile aroma compounds (grape-derived aromas, aromas produced from the process of fermentation, maturation aromas), the chemistry of aromas, and the genetic bases of aroma formation.
