Grapes and wine overview

Grape genetics

Colour and flavour

CSIRO is studying the molecular and biochemical regulation of the synthesis of anthocyanins, which give red wine its colour.

We are also studying tannins which add mouthfeel and texture.

This research will help improve wine grapes and, ultimately, wine.

Fruit quality

Flowering and fruit development determine yield and fruit quality. A genomics approach is being used to identify the genes regulating flowering and fruit development and their interactions in grapevines.

By studying the expression pattern and function of genes expressed in grape berries we can then ascertain how they influence fruit and wine quality.

CSIRO is also determining the effect of environment and management practices on gene activity and processes controlling yield and berry composition.

We aim to develop grapevines that combine fruit and wine quality with resistance to powdery mildew.

Disease resistance

We aim to develop grapevines that combine fruit and wine quality with resistance to powdery mildew.

It is estimated that Australian grapegrowers use more than A$30 million worth of fungicides on grapevines each year to prevent or treat outbreaks of powdery mildew.

We aim to develop grapevines that combine fruit and wine quality with resistance to powdery mildew, using natural genes from American grape species.

We regularly review the grape genomics program and discuss strategic directions in internal and industry linked workshops.
