Harvest 2024 ramps to full speed, then cools down. Our vines (and our people) appreciate the respite.

On Monday night, I was snuggling under a blanket reading in our living room when I realized that it smelled like snow. No, it was never actually going to snow. Snow happens only once every few years in Paso Robles, and never in September. But that didn't change the fact that after a two month stretch that has ranged from warm to hot, the air felt different. It was already down in the 40s just after 10pm, and the crisp, electric air and the north wind would have sent me, if it were April, to check on our frost protection. In the end, it didn't come all that close to freezing. At my house it bottomed out at 38.7F, and at the vineyard it was a couple of degrees warmer. But that night, and the chilly, breezy day that followed and topped out only at 67.4F, definitely felt like a harbinger of the changing seasons. You can see from the chart below how different the last week has been compared to the beginning of September: 

As for the Tablas Creek harvest, this cooldown is giving the team a chance to catch their breaths after a rapid escalation of harvest. The first couple of weeks started slow, as we brought in 44.8 tons across those two weeks. The next week was a doozy. We brought in over 115 tons including one lot each of Viognier, Marsanne, Roussanne, Clairette Blanche, Grenache Blanc, and Vermentino, four lots of Grenache Blanc, seven lots of Grenache, ten lots of Syrah, and two co-harvested lots. Nineteen of these lots came off the estate, nine will go into Patelin, Patelin Blanc or Patelin Rosé, and one will become our newest Lignée de Tablas wine: a white blend from the Fenaughty vineyard in the Sierra foothills. The harvest chalkboard is filling up:

A few scenes from around the cellar will help give you a sense of things. First, the bins sitting on our crushpad, in this case Mourvedre (left) and Grenache (right):

Next, the daily chart that keeps track of our cap management for all our fermenting reds (notice the division into "pump over", "pulse air", and "punch down") as well as what's being received and pressed that day:

I'm guessing you're likely less familiar with what "pulse air" is than you are with pump over or punch down. For us, it's an important part of our program, and a way to keep the fermenting reds mixed without extracting harsher tannins. You need to do this mixing daily, at least, because the carbon dioxide bubbles that form during fermentation lift the berries to the surface, forming a "cap" or cake of mostly-whole berries at the top of a deeper pool of fermenting juice. You want the juice in contact with the berries because that's how you get the flavor extraction. In addition, leaving the berries to dry out at the surface invites problems such as spoilage yeasts. So typically you either push the berries down into the juice manually (that's a punch-down) or you pump the juice out from the bottom of the tank and spray it on the cap (that's a pump-over). But both have the potential to extract more of the harsher tannins than you might want: punch-downs because you're physically crushing the skins with each punch, and pump-overs because the pump's machinery ends up grinding up seeds that may have fallen to the bottom of the tank. The pulse-air, on the other hand, uses an air compressor and a long wand to release bubbles of air in the fermenting liquid. As that bubble escapes to the surface, it splashes apart the cap. This typically results in a gentler extraction. You can see the pulse-air in action below on one of our 1500-gallon wooden upright tanks, wielded by harvest intern Rachel:

In the vineyard, things have progressed rapidly, and everywhere you turn there is a jewel-like cluster of grapes, hanging enticingly. I particularly like the white clusters at this stage, as they pick up their first hint of honeyed tones. These Bourboulenc clusters should come in sometime in the next week or two:

At the same time, there are still clusters that are a long way from being ready to harvest. And that's just fine; we don't expect to bring in the last fruit until the end of October. This Grenache cluster is still going through the final stages of veraison:

I've been enjoying trying to come up with new perspectives on the ever-changing vineyard. One of my favorites has been to get underneath the vines and use a wide-angle to try to get the hanging clusters, the canopy, and the horizon line. Below you can see the results with Grenache (left) and Bourboulenc (right):

This week's cool-down hasn't meant that we've stopped harvesting. If you look at the harvest chalkboard above you'll see that we brought in nine different lots already this week. But it does take the pressure off. We were able to take yesterday and get our presses a much-needed servicing. We used some down time on Tuesday to get our recently-arrive 600-gallon foudres stacked and settled in our white room. We didn't harvest either weekend day last weekend. And we've been able to get the cellar team home by 4pm the past few days. That may not seem like much, but a week like last week meant 60 work hours for much of the team. Having a mellower week to recharge everyone's batteries is most welcome. 

Similarly, the cooler weather gives the grapevines a chance to recuperate and gather energy for their next push. The weather looks like it will warm up next week, not to any noteworthy level, but back into the 90s. Then things will get back on track.

One thing I'm going to be keeping my eyes on is yields. We're starting to get signals, mostly from our Patelin growers, that certain varieties are coming in much lighter than people expected. This seems to be particularly true with whites, although given that whites are mostly ready before reds, it's possible we'll see that reds will end up lower too. On our own property, it seems like Syrah, Grenache, and Grenache Blanc have pretty healthy yields out there. Viognier and Vermentino definitely look light. Roussanne, Counoise, and Mourvedre seem average to a bit below. But given that we haven't finished picking anything off our estate yet, it's hard to have the full picture. But I think we can conclude that our hopes of a truly plentiful vintage aren't going to come to pass. Look for more details in our next harvest update.

Meanwhile, I'm going to leave you with one more photo, taken by Vineyard Manager Jordy Lonborg at 4am yesterday. That's the nearly-full moon behind some high clouds, with the stacks of empty picking bins in the foreground. I'm not sure I can remember a more atmospheric harvest photo. There are moments of beauty every day out here. At this time of year, most nights, too.
