What is an aszú grape?

Botrytis (Noble rot)

The fungus Botrytis cinerea settles on the ripe or very ripe grape. It only appears when the necessary amount of humidity is present - coming either from damp autumn weather or vapour and fog rising from the Tisza and Bodrog rivers and their oxbow lakes. First the fungus enters the grape weaving its threads through the flesh. In some vintages the fungus develops on the skin. In response to the Botrytis, the grape creates aroma precursors that will be changed later and bring the specific "Botrytis" notes of citrus. It is important that the Botrytis settles on ripe grapes, otherwise it causes grey or green rot.

 

Shrivelling

As a result of Botrytis and full ripeness and Botrytis, the skin of the grape becomes thinner and develops holes, so the water evaporates more easily. As the grape loses water, it shrivels and becomes an aszú grape in which the sugars, acids and flavour components are increasingly concentrated. Warm autumn winds and sunshine also aid the natural shrivelling process.
