Hens and chicks.

Hurrah!  Veraison in the Syrah.  I actually noticed the onset of veraison yesterday and it's quite irregular, but it's happening.  I also noticed that there is quite a bit of poor fruit set, or millerandage, in the Syrah (not shown in this photograph).  Sometimes referred to  as 'hens and chicks', I am used to seeing this phenomenon in the Orange muscat vines, but not usually in the Syrah.
Millerandage is a problem that affects fruit set in grapes and can be caused by a number of things; unfavourable climatic conditions, difficult fertilization, genetics, etc.  With millerandage, flowers that fail to fertilize remain on the cluster, (unlike with coulure, another form of poor fruit set, in which the flowers abscise and fall off), becoming small, seedless berries commonly known as shot berries.  Methinks the culprit was most likely wind, as I think this has been a rather windy spring/summer in the valley. Whoosh!  Bye-bye, crop.

Yikes! What contrast! Makes for an interesting photo though.

NHW: The onset of veraison is always quite dramatic in the black grapes (and Pinot grigio).
