Wine is never really finished.
That might sound strange. Once wine is in a bottle, it can seem like the process is over. But wine continues to change, and that process begins long before the bottle is ever filled.
It begins in the vineyard.
As harvest approaches at Billsboro, we’re watching the grapes move through one of the most important stages of their lives. Every day on the vine changes what those grapes will eventually become, and at some point, our winemaker has to decide when they’re ready to make that next transition.
That’s one of the things we love about wine: it is always becoming something.
What happens to a grape as it ripens?
A grape changes considerably during the growing season. By the time we reach harvest, the berries have accumulated sugars, developed flavor and aroma compounds, and undergone significant changes in their acidity and structure.
One of the easiest changes to understand is sugar. As grapes ripen, their sugar concentration increases. Winemakers measure this using Brix, a measurement that helps estimate the amount of sugar in the grape and, ultimately, its potential alcohol after fermentation.
At the same time, acidity generally decreases as the grapes mature. Acidity contributes the freshness and structure we experience in a wine.
So even before the grape becomes wine, its chemistry is already changing. And that chemistry matters.
The balance between sugar, acidity, flavor, and other compounds in the grape will help determine the character of the wine that comes later.
When is a grape actually ready?
This is where the winemaker comes in.
There isn’t a single number that tells a winemaker when to harvest. A grape might reach a certain sugar level, but that doesn’t necessarily mean it’s ready.
The winemaker is looking at the whole picture.
They may measure Brix, pH, and acidity. They’ll taste the grapes. For red varieties, they’ll pay attention to the skins and seeds and the development of tannins, which contribute color, texture, and structure. They’re also watching the weather.
Because the decision to harvest isn’t simply about asking, “Are these grapes ripe?” It’s about asking: “Are these grapes ready to become the wine we want to make?”
More time isn’t always better
It’s tempting to think that leaving grapes on the vine longer must result in a better wine. But that’s not necessarily the case.
As grapes continue to ripen, sugar generally increases and acidity decreases. Flavors continue to develop, too. But the longer grapes remain on the vine, the more they are exposed to weather and other risks.
And different wines call for different balances.
A winemaker may choose to harvest earlier to preserve acidity and freshness. Another wine may benefit from allowing the grapes more time to develop additional ripeness and flavor. The goal isn’t maximum ripeness. The goal is balance.
That means harvest timing is one of the most consequential choices a winemaker makes.
The season becomes part of the wine
And this is where wine starts to feel a little like a living thing. The grapes aren’t developing in isolation. They’re responding to their environment.
Sunlight. Rainfall. Temperature. Soil. The length of the growing season.
All of these factors influence how the grapes develop, which means every vintage begins with a different set of circumstances.
A winemaker can guide the process, but they can’t recreate the exact conditions of another year. That’s part of what makes vintage wine so interesting. The wine carries something of the season in which it was grown.
Then the transformation continues
Once the grapes are harvested, they begin another stage of their lives.
Fermentation transforms grape juice into wine as yeast converts sugar into alcohol and carbon dioxide. From there, the wine continues to develop through aging and time.
But the winemaker’s work isn’t about forcing the wine into existence. It’s about responding to what the grapes have given them.
The growing season establishes one part of the story. Harvest timing shapes another. Fermentation and aging add more chapters. Eventually, the wine reaches the bottle. And even then, it can continue to change.
A little like us
Maybe that’s why the process feels so familiar. Most of us aren’t the same people we were a year ago, or even a few months ago. We change with our surroundings. We learn. We adapt. We move through different seasons of our lives. And, like wine, we don’t become something new all at once.
There are small changes happening all the time. Harvest is a reminder of that.
Right now, the grapes at Billsboro are approaching an important transition. Soon, we’ll decide when they’re ready to leave the vine and begin the next stage of their lives in the cellar. We’ll watch them change there, too. And eventually, they’ll become something that can be shared. A bottle opened around a table, brought to a new home, poured for an old friend, or enjoyed at the beginning of a new chapter.
The wine will have changed many times by then. But it will still carry the story of where it began.
A particular place. A particular season. A particular moment in time.
Maybe that’s what makes wine such a natural companion to life’s transitions. It reminds us that becoming something new takes time. And sometimes, it takes knowing when the moment is right.
A Bottle for the Season
As the seasons change around us, we hope you’ll find a bottle that meets you wherever you are right now. Open it with someone you love. Bring it to a new beginning. Pour a glass at the end of a long week.
Whatever this season looks like for you, we hope there’s a little time in it to slow down, gather, and enjoy where you are.
