It is now well over a month since the big frost and from a distance many of the vines look OK with green shoots pushing upwards. However, close inspection shows that in the frost affected vineyards this growth is coming from the trunk with very little in the way of potential bunches, while most of the buds on the cane are shrivelled and dead.
On closer inspection the frost damage is clear with
only the occasional bud surviving on a cane
