Number of Days from Budbreak to Harvest for Our Varieties

I have been reading over my blogposts from the past and came upon one that I wrote in 2018 called Vine Cycle and Vineyard Activities. In that blogpost, I calculated the number of days from budbreak to harvest for our Auxerrois, Chenin Blanc and Chardonnay. Since that time, we have a few more data points that we can add so here is the updated chart.

Barbera May 2, 2020 October 28, 2020 172

This chart shows at a glance how many days it was from budbreak to harvest for our varieties. It shows that the Auxerrois is the first to ripen and consequently gets harvested first, followed by the Chardonnay, Chenin Blanc, the two Cabernet varieties and then the Barbera. It also shows the number of days from budbreak to harvest so that we can get an idea of when the various grapes will ripen in any given year, subject to Mother Nature (of course).
