Veraison 2022 Sets the Stage for a Coin Flip: Will This Be Our Earliest Harvest Ever?
July 26, 2022
I got back this week from spending most of a month in Vermont to find a very different vineyard than the one I left. Instead of growing but bright green, pea-sized berries, the grapes have become full-sized and rainbow shades of purple, red, pink and green. This Grenache cluster is a great example of the diversity of color:
Veraison, if you're unfamiliar with the term, is a physiological stage of grape development where the berries stop accumulating mass and start accumulating sugar. More visibly, red grapes start their color change from green, while white grapes take on more of a yellow tint. Both red and white grapes start to soften. This landmark comes roughly six weeks before the onset of harvest, and gives us our best estimate for when harvest will begin.
Although this week has been an exception, the last month of the 2022 growing season has been warm. In the 35 days since the calendar turned to summer, our average high temperature has been 93.5°F. Eight days have topped 100°F, with another fifteen topping out in the 90's. Just one day failed to make it into the 80's. But July is almost always hot in Paso Robles, and that average is less than what we saw in July 2016, 2017, 2018, and 2021. And I was pleased with the vigor and health of the vines in my rambles around it today and yesterday. July is typically when the vineyard starts showing signs of the marathon that is the growing season. Not this year, or at least not yet. But it's definitely been warm enough to push veraison into high gear.
We spotted our first color in the vineyard on July 12th. Now, two weeks later, Syrah is moving fast, and the others getting started. I thought it would be fun to give you a visual tour. I'll start with Syrah, as usual the first Rhone red to enter version and the fastest to change colors. The cluster on the right is a little ahead of average, mostly red but still with a few green berries finishing up, while the cluster on the left is more typical:
Grenache is next in line. I think it's the most beautiful grape in nearly every season, but in veraison it outdoes itself, with the berries turning jewel-like in the sun. Look for lots more Grenache pictures in the next month, as we get further along than the 10% veraison I'd estimate we have now:
Mourvedre, even though it's typically the last to be harvested, is the next-most-advanced, well further into veraison than Counoise and only slightly behind Grenache. Note though that this doesn't mean it's going to be picked any time soon; it often has relatively early veraison and then just spends a long time in this last stage of ripening. This cluster is one of the more advanced ones, and I'd estimate it's only at 5% veraison overall:
Finally, Counoise. It took some searching to find any color. This cluster, with a few pink-purple berries in a sea of green, is about as advanced as it gets. I'd estimate we're around 1% on Counoise, overall:
Although it's less exciting visually than with reds, white grapes too go through veraison. The grapes turn from green to something a little yellower, and soften and start to get sweet. They also become more translucent. The process happens over a continuum as it does in the reds. Viognier goes first, followed by Vermentino, Marsanne, and Grenache Blanc, with Picpoul and Roussanne bringing up the rear. You can see the slightly golden tone that this Viognier cluster is starting to pick up:
It's important to note that while the veraison posts you're likely seeing from your favorite wineries may make it seem like veraison is a moment, like Christmas, it's probably better understood as a continuum, like winter, and first veraison is like first frost, or first snowfall. It will likely be a week or two so before even all the Syrah clusters are red, and more than a month until the last clusters of later grapes like Mourvedre and Counoise have finished coloring up.
While six weeks is a good basic guide for the duration between veraison and harvest, it's not totally constant, and can be influenced by the weather that we get in the interim, as well as by the amount of fruit the vines are carrying and the inherent tendencies of the different varieties. For example, a consistently cool August in 2018 gave us more than six weeks between veraison and our first harvest on September 10th, while last year's consistent heat and low yields gave us just a five week interim. The last decade is compiled in the chart below, with each year linked to my blog post about that year's veraison:
|Year||First Veraison Noted||Estate Harvest Begins||# of Days|
|2012||July 25||September 5||42|
|2013||July 17||August 26||40|
|2014||July 9||August 23||45|
|2015||July 18||August 26||39|
|2016||July 13||August 18||36|
|2017||July 20||August 30||41|
|2018||July 29||September 10||43|
|2019||July 30||September 4||36|
|2020||July 21||August 25||35|
|2021||July 21||August 24||34|
Using the range of durations between first veraison and first harvest (34 to 45 days) we can have good confidence that we'll begin picking sometime between August 15th and August 26th. The weather between now and then will determine where in the range we'll fall, influenced as well by the crop levels, since lighter crops ripen faster than heavier ones. It looks like we're seeing medium crop levels this year, better than last year but not at the levels we saw in a year like 2017, which suggests we'd trend toward the earlier end of the range above, but maybe not challenge last year's record-short duration. Still, we have a chance of besting 2016 for our earliest-ever beginning to harvest.
What's next for the vineyard? We'll watch the different grapes go through veraison. That progress is already happening fast, and the view in the vineyard is changing daily. We'll be posting regular photos of veraison's progress on our Facebook, Twitter, and Instagram pages. I spent some time yesterday with our Viticulturist Jordy Lonborg, and he's excited about the vines' health. It looks like we lost a little crop to sunburn during the heat spikes, but nothing crippling, and the vigor in the vineyard should give the vines the ability to make a strong finishing push. In a few weeks, we'll start sampling the early varieties, looking for the moment when the flavors are fully developed and the balance of sugars and acids ideal. In the cellar, we'll use that time to finish bottling the last of our 2020 reds, refill those barrels and foudres with our newly-blended 2021s, and get started cleaning and checking all the tanks and equipment we'll be using once harvest begins.
So, now we wait, and enjoy the show. We may not know exactly how much time is on that timer, but we can hear it starting to tick.
