A crucial part of harvest is the transition between picking Sauvignon Blanc and picking Zinfandel, whose ripening window is extremely narrow. This year, smooth sailing with SB, combined with a very welcome week of cool weather just as the Zin got ripe enabled us to jump on top of the Zinfandel harvest and prevent sugars from getting out of control. The 2024 Zins already have a vibrancy that rivals the 2023 vintage, with slightly lower alcohol levels to boot—I can’t wait to see these wines develop. Simultaneous with Zinfandel was the Chardonnay harvest. While the 2023 Chard harvest was spread out over a whole month, the 2024 edition took just 12 days from start to finish, again with great flavors and freshness.
There were two main differences between 2023 and 2024 for the Merlot and Cabernet harvests. First, crop level—whereas the 2024 crop was moderately below average in size, the 2023 yields were quite large, especially compared to the drought years that we had just exited. This factor combined with very cool, almost cold weather in 2023 to extend the harvest very late into the fall, while 2024 featured much more of the “normal” combo of warm days and cool nights. Consequently, we wrapped up 2024 almost a month earlier in 2024 than in 2023 (November 2nd vs. October 8th).
Referencing the “early” (actually, normal) end to harvest, some will point to a heat wave that rolled through the valley in early October, and I’ve heard some early comparisons to the 2022 harvest heat wave. However, I think that’s a bit of a red herring—the heat wave in 2024 occurred almost a month later into harvest than in 2022, after our sensitive blocks at Rossi and Leeds had already been picked, and when what was left to pick was already either ready or almost ready. Much larger canopies than in 2022 helped give better protection to the fruit, and we were able to ride out the wave without having to use any of our heat suppression systems. In the end, the heat seemed to “pop” some blocks that needed a little push, and the remaining fruit came in problem-free.
