Vines will often produce more fruit than the trunk and root system can support, which can stress the vine and also result in the bunches not ripening properly. This isn't a big problem for us this year, as many of the berries didn't pollinate properly which has resulted in small and incomplete bunches (see earlier post - Coulour and Millerandage).
Non the less Alex has convinced me that we should cut off any 3rd and 4th bunches on any one cane, so that the grapes have the best possible chance of ripening in this dreadful weather. Whilst good quality sparkling wine can be made from fairly acidic grapes, we need fruit with a reasonably high sugar content to make a good quality still rosé.
All in all it's been a pretty dreadful year so far weather wise. We are still hopeful of releasing our first rosé wine next year but will only do so if the quality is good enough. Hopefully an Indian summer!
