Veraison - the onset of ripening - is a turning point in the vine’s life cycle when it changes gears from producing energy through photosynthesis to storing that energy as sugar in grapes.

After flowering and fruit-setting, the grapes are hard, highly acidic, and green from the plant’s chlorophyll. Veraison replaces the chlorophyll with anthocyanins (giving red grapes their color) or carotenoids (in white grapes) and pumps sugars and other compounds from the vine into the berries. Over the course of ripening, the grapes swell with juice, their percentage of sugar (measured in brix) increases, and their acidity falls. Choosing to harvest when the sugar, acidity, and other phenolic compounds like tannins are perfectly balanced is one of the most important decisions a winemaker has to make each vintage.

In Burgundy, veraison classically happened in late July, although rules of thumb are obviously out the window in recent years with climate change. This vintage, winemakers are seeing veraison start to happen right now. The precocious vintage continues…

Continued warm weather in Burgundy means that the vines are still progressing at a very fast clip. Here, Nicolas Rossignol shows us La Nouaison (Fruit Setting) of his Volnay Taillepieds where the berries are growing rapidly. In some of his parcels, the clusters are nearly fully formed. Winemakers all over France are marveling at the precocity of their vines this year, with some areas an entire month ahead of the average growing season.

Nicolas Rossignol shows us the progress of his Volnay Taillepieds - we see here the flowers transforming into the beginnings of grapes. Henri Jayer used to say that maturity would be reached 100 days after the start of flowering, so Nicolas estimates a pick date between August 28 and September 2 at this point - another early harvest!

Due to high temperatures in Burgundy in the last two months, some vineyards are already flowering. Compared to 2019, the vines are reaching the flowering stage three weeks earlier.

As Brice de la Morandière reminded us in last Saturday’s At Home Session, the harvest date is typically scheduled 100 days from the flowering. If this calculation is applied this year, the harvest would start in August.
