Annual Cycle of Growth - Véraison

On Saturday, August 13, we took the Brix of the Auxerrois and it was 11 degrees. Yesterday, we sampled a few more berries and in the span of 5 days it went from 11 to between 13 and 15 degrees Brix! The Auxerrois are definitely on their tragectory to ripening. All the nets are secured around the ripening grapes so it was time to turn our attention to the Chardonnay. The Chardonnay was also softening and when we tested the Brix it was at 10 Brix!
We have been keeping a chart of the annual cycle of growth for our varieties so it is time again to begin to fill the chart to indicate véraison for 2022.

Keeping a chart of this sort allows us to see if our varieties are on track with previous years and helps us to plan for harvest. If this chart is any indication, the next varieties to enter véraison would be the Cabernet Sauvignon and Cabernet Franc. The red varieties are easy to check for véraison because the skins will turn from green to red.
Looks like the grapes are following their internal clocks!
