Wine aroma and flavour
A thorough knowledge of the relationship between wine composition and aroma/flavour, including mouth-feel, is pivotal in understanding grape and wine quality.
The large body of research conducted at the AWRI and overseas has given excellent insight regarding how numerous compounds contribute to wine aroma and flavour; how they are formed;, and how they are degraded. Nevertheless, many flavour properties, both desirable and undesirable, remain inadequately explained. These flavours include many important varietal and bottle-age characteristics, including those associated with the influence of oak, wine microorganisms and oxidation, as well as undesirable taints, ‘off-flavours’, ‘reduced’ and ‘green’ sensory attributes.
Improved knowledge of quality determining components, is fundamental to enable viticultural and winemaking practices to be optimized.
