Why is knowing the date of flowering important? With the data that we have been tracking, we believe that between flowering and harvest, in our vineyard, it is approximately 90 days. If flowering came on July 6th, that puts harvest around October 4th.
We have come to learn that our Chardonnay is always the first to bloom (also called anthesis), but we were surprised to see that our Cabernet Franc was also in bloom! On June 21st, here is where our vineyard stood with respect to percentage flowering:
Variety | % Bloom on June 21 |
Chardonnay | 50% |
Cabernet Franc | 40% |
Auxerrois | 40% |
Chenin Blanc | 10% |
Cabernet Sauvignon | Not in bloom yet |
Since flowering is a full 2 weeks earlier than what I thought, our harvest should be more like the end of September, Mother Nature willing!
