(Wine-Searcher) - A turnaround in the weather means producers in Burgundy have quantity as well as quality in this year's harvest.

Many Burgundy vintners finished picking earlier this week and Claude Chevalier, president of the BIVB said that yields are "almost back to normal" following a string of lower-than-average production vintages.

At his own Burgundy estate – Domaine Chevalier in Ladoix-Serrigny – Chevalier said: "The berries have good concentration, with phenolic ripeness", and – importantly – there were plenty of them.

At the sorting table, they had rejected some unripe grapes and just a few gave off slight vinegar aromas of acetic rot – a result of the unexpectedly high number of Drosophila suzukii "vinegar flies" that struck vineyards during the September harvest.

"They love cherries and, because the cherry season lasted a long time, the flies stuck around to attack grapes in September," Chevalier said. Furthermore, temperatures in the high 20s (mid 80s F) favored their presence from the end of August through to the harvest, he explained.

Overall about 1.45 million hectoliters (38.3m gallons) of wine is expected from Burgundy, from Chablis to the Mâconnais, while the average vintage yields 1.5m hectoliters. This figure takes into account higher-than-average production in the Côte de Nuits, but a drop in production in much of the Côte de Beaune and the Mâconnais due to a terrible hailstorm in late June.

Cool temperatures and well-above-average rain in July and August would prevent 2014 from being an "exceptional" vintage, said Sylvain Pitiot of Clos de Tart in Morey-Saint-Denis, in the Côte de Nuits. But the three weeks of hot and sunny days in September "really did save the harvest", he said and "we should have a very good vintage".
