A few properties in Burgundy began harvesting on Monday, but most will begin tomorrow, as vignerons predict a 'good but not great' year. With three times as much rain as normal – 130mm – falling in July and August, there have been problems with rot and some vignerons are predicting a 20% drop in yield. There may also be a need to chaptalize – add sugar – to raise alcohol levels. ‘It is time to harvest,’ said Thierry Brouhin, director of Clos des Lambrays in Morey St Denis.
