How We Decide When to Pick: The Numbers, the People, and the Moment
By Emanuel Varda, Managing Partner & Vintner
In late July, a lab report arrived for Pinot Noir at Sunset Knoll Vineyard. We were considering the fruit for our first traditional-method sparkling wine, and the sample showed 19.2° Brix, a pH of 2.87, and the kind of natural acidity that can become the backbone of a fresh, elegant sparkling wine.
On paper, the fruit was close to where we wanted it. In practice, the report did not give us an answer. It gave us a window—and a short one.
The forecast suggested the vineyard could move quickly. We believed we had roughly four or five days to coordinate with the grower, confirm when the fruit could be picked, schedule the crush, finalize dry goods, and make sure the base-wine fermentation plan was ready.
That is what a pick decision feels like from our side. A number may start the conversation, but the actual decision includes the wine we are trying to make, the taste and condition of the fruit, the grower’s experience, the weather ahead, and whether the cellar is ready to receive what the vineyard has spent an entire season growing.
The Hardest Part Is Moving Before Everything Feels Certain
One of the hardest lessons of harvest is that certainty usually arrives after the best decision window has started to close.
It is tempting to ask for one more sample, one more day, or one more conversation. Waiting can feel responsible because it delays the risk of being wrong. But the vineyard does not pause while we become more comfortable. Sugar can rise, acidity can fall, heat can dehydrate the berries, and the style we were protecting can begin to move away from us.
When Wine & Barrel was only an idea, I imagined harvest decisions as a clear progression: sample, review the numbers, choose a date, and pick. The real experience is less orderly. Crews, bins, transport, crush schedules, tanks, yeast, and a dozen smaller details all have to meet one biological moment. That realization changed the way I think about readiness. Preparation is not separate from wine quality. It is part of protecting it.
The emotional side is real too. When the fruit looks promising, excitement arrives first. Then comes the weight of knowing that the next decision cannot be reversed. Once the grapes leave the vine, we cannot give them another week or return the freshness we allowed to pass.
The Wine Style Sets the Target
Before I ask whether the grapes are ready, I begin with a more important question: What am I asking this fruit to become?
Fruit intended for a sparkling base wine needs brightness, natural acidity, and precision. Waiting for a deeper level of ripeness might produce more sugar and flavor weight, but it could also take away the energy the finished sparkling wine needs.
For THE DAWN Rosé, we wanted delicate red fruit, freshness, and a clean, dry finish. For our still Pinot Noir from the same Los Carneros vineyard, we still wanted lift, but we also needed the skins and seeds to develop enough texture and structure for the red wine ahead.
Cabernet asks for a different kind of patience. We need tannins to mature and flavors to become complete, but we are not trying to wait for the highest possible sugar. We want depth that still carries freshness and a structure that feels shaped rather than heavy.
Style does not replace chemistry or taste. It tells us how to interpret them.
One Cabernet, Two Vineyards, Three Weeks Apart
THE NINTH BARREL Cabernet Sauvignon gives us a useful real example. The 2024 wine is an even blend of Cabernet Sauvignon from Rutherford and Spring Mountain. The Rutherford fruit was harvested on September 30. The Spring Mountain fruit was harvested on October 21, three weeks later.
Those dates were not evidence that one vineyard was ahead and the other was behind. They reflected two sites moving on their own timelines. The valley-floor fruit and the mountain fruit did not need to arrive together to belong in the same wine.
If we had chosen a date because it was convenient for the blend, we would have asked one site to behave like the other. Instead, we allowed each component to reach the balance it needed, then brought them together in the cellar.
That experience is one reason we resist universal harvest numbers. A pick date only makes sense in the context of the vineyard and the wine ahead.
Chemistry Gives Us Direction, Not Permission
We follow Brix, pH, and titratable acidity because each tells us something important about how the fruit is moving.
Brix gives us a view of sugar and potential alcohol. pH helps us understand the acidic environment that will influence freshness, color, stability, and how the wine behaves in the cellar. Titratable acidity, or TA, gives us another view of the fruit’s acid balance and often connects more directly to how tart or lively the juice tastes.
As grapes ripen, Brix and pH generally rise while TA falls. None of those movements happen in isolation. A warm stretch can raise Brix through dehydration before the flavors or tannins have developed in the way we want. A familiar Brix number can therefore look reassuring while the rest of the fruit tells a different story.
Earlier in this process, it was easy for me to believe the strongest pick decision would be the one with the cleanest number behind it. Harvest has taught me that numbers are better at explaining a decision than making one. They give us direction. They do not give us permission to stop paying attention.
Then We Taste What the Lab Cannot Measure
We taste berries from different rows and positions in the block. We look for flavors moving away from hard, green, or overly herbal notes and toward the character we expect from the variety and site. We pay attention to whether the acidity feels sharp, lively, or already beginning to soften.
For red wines, we chew the skins and taste the seeds. Tough skins and green, bitter seeds can tell us the fruit still needs time, even when the sugar looks familiar. We also look at the physical condition of the clusters. Shrivel, sunburn, dehydration, rot, or uneven ripening can change the decision quickly.
We repeat the sampling because one bucket is only a snapshot. A vineyard block is not uniform. Fruit at the edge can move differently from fruit deeper inside, and sun exposure, soil, vine vigor, irrigation, and crop load create variation that an average number can hide.
Trust Changes the Quality of the Decision
The grower lives with the vineyard long before we arrive with a sample bag. They see the block in the morning, after a warm afternoon, and through changes that may not appear in a lab report for another day or two.
We depend on that perspective. We share the style we are trying to make, what we are seeing in the chemistry, and what we are tasting. We ask the grower what has changed, which rows are moving first, and whether the physical condition of the fruit is beginning to create urgency.
Trust does not mean everyone agrees immediately. It means the conversation can be honest. A vineyard partner who tells us the fruit is moving faster than our schedule is protecting the wine, even when the message creates more work. In return, we need to be clear about what we value and ready to act when the fruit reaches the window we asked them to help us find.
What the Early 2026 Harvest Has Changed
This season has made every part of that relationship more visible. Sampling has become more frequent. Forecasts carry more weight. Vineyard, cellar, and dry-goods decisions have had to come together sooner than the calendar suggested.
The planned August “pre-harvest” story became outdated before August arrived. The vineyard moved first, and our content calendar, like our production calendar, had to move with it.
There is humility in that. We can build detailed plans, but the fruit does not know the dates we placed on them. Our responsibility is not to force the season back into the plan. It is to stay close enough to recognize when the plan needs to change.
The Decision We Can Stand Behind
There is no universal number that tells every vineyard it is time to pick. If there were, harvest would be easier, and the wines would be far less interesting.
For us, the right moment is when the intended style, the chemistry, the taste and condition of the fruit, the grower’s experience, and the readiness of the cellar begin pointing in the same direction.
When someone eventually opens the bottle, they will not see the spreadsheet, the forecast, or the four days of phone calls that led to the pick. They will feel the result as freshness, texture, balance, and a wine that belongs at the table.
That is the decision I need to be able to stand behind, not because it was perfect or easy, but because it was true to the fruit and the wine I set out to make.
