A persistent heatwave in much of Europe has meant flowering earlier than almost anyone can remember in some wine regions and a particularly early harvest is predicted.
In general, early harvests have tended to be a sign of quality in Europe's fine wine regions BUT all sorts of possible disasters may strike between now and vintage time.

Or if seriously high temperatures persist the vines may simply be too stressed to ripen...
