What is veraison? Grape ripening, explained

Walk our rows right now and you'll catch it happening in real time: clusters that were solid green a few weeks ago are starting to blush purple and turn gold. This is veraison, the stage of grape ripening when wine grapes change color, begin to soften, and start building sugar and flavor before harvest. It happens in the weeks leading up to harvest, and it's the clearest sign the season is heading into the home stretch.
It's happening right now at Parrish Family Vineyard in the Adelaida District of Paso Robles wine country, and we wanted to show you what it actually looks like. Watch the video below, and continue reading to learn more about this stage in the growing season.
The growing season, in a nutshell
Getting to veraison takes a few months of work:
- Bud break: the vines wake up from winter and push out their first leaves.
- Flowering: tiny flowers appear and, if all goes well, get pollinated.
- Fruit set: those flowers become small, hard, green grapes.
- Veraison: the grapes change color, soften, and start ripening.
- Harvest: once the fruit hits the right balance of sugar and flavor, we pick.
What happens during veraison?
A few things happen at once, over just a couple of weeks:
- Color changes. Red wine grapes shift from green to red or purple. White grapes turn from green to a soft gold.
- Berries soften as they shift from growing bigger to ripening.
- Sugar starts building up, while the grape's natural acidity starts to drop.
This process doesn't happen evenly. Some berries change color before others, even on the same cluster. That's normal, and it's part of why we keep a close eye on the vines through this stretch.
What happens next?
Once color change starts, our focus shifts from growing the fruit to ripening it well:
- We start tasting and testing fruit regularly to track sugar and flavor development.
- We manage the leaves around the clusters so the fruit gets the right amount of sun.
- We watch each block closely, since some varieties like our Sauvignon Blanc tend to ripen first, with our red varieties following a few weeks behind.
- When a block is ready, we pick and sort it by hand, so only the best fruit makes it into the wine.
