The Vine Growth Cycle: From Bud Break to Harvest

Wine begins long before it reaches your glass. It starts in the vineyard, where vines follow a natural growth cycle throughout the year. Understanding this cycle can provide deeper insight into how grapes develop and, ultimately, how they shape the flavors in your favorite bottle.

In the spring, Virginia’s vineyards have entered the early stages of the growing season, beginning with bud break. This marks the start of the vintage and sets the pace for the year ahead. Here’s a look at the key stages of vine growth you’ll see throughout the year.

Bud Break

When temperatures begin to rise in the spring, Virginia’s vines awaken from their winter dormancy. Bud break marks the start of a new growing season. The buds swell until they burst, growing into shoots that will later hold fruit. Due to Virginia’s varied microclimates, bud break timing can differ between regions. Early-budding varieties like Chardonnay and Viognier are often the first to emerge, while others, like Cabernet Sauvignon, take more time and warmth.

Flowering & Fruit Set

By late spring, tiny clusters of flowers begin to bloom on the vines. Successful pollination of the flowers leads to fruit set, where the flowers develop into small, green berries. Virginia’s humid climate plays a key role during this time. Excessive rain can lead to poor fruit set or mildew issues, which is why vineyard management is so important. Canopy management techniques help improve airflow and reduce disease pressure.

Veraison 

After fruit set, grape varieties, both red and white, are green and hard. As the summer progresses, they begin their transformation. White varieties like Petit Manseng and Albariño turn golden, while red grapes like Cabernet Franc, Norton, and Tannat shift from green to deep red and purple hues. This process, called veraison, is a beautiful sight, with clusters of green and red berries scattered throughout the vineyard. At this stage, grapes begin to ripen and increase their sugar levels.

Harvest

Harvest is one of the most exciting times in Virginia wine country. Winemakers carefully monitor sugar and acidity levels to determine the perfect moment to pick. White grapes—along with those used for rosé and sparkling wines—are typically harvested first, while red varieties like Cabernet Franc, Petit Verdot, and Tannat need more time to develop their tannins, making them among the last to be picked. Harvesting can be done by hand or machine, and both methods can yield high-quality results. From August through October, Virginia’s wine regions come alive with Harvest Party celebrations, inviting visitors to experience the energy and joy of the season firsthand.

Dormancy  

After the excitement of harvest, the vines eventually enter their winter rest. Before falling, the leaves turn beautiful hues of red, gold, and orange. During dormancy, the vine conserves energy, storing nutrients for the next growing season. 

During winter, viticulturists prune the vines, removing unnecessary growth and shaping the structure of the vine for the coming year. This essential work ensures that Virginia’s vineyards remain healthy and productive, ready to restart the cycle when temperatures rise again in the spring.

As the seasons cycle through Virginia’s vineyards, each stage of growth shapes the wines that capture the essence of the region. From the tender buds of spring to the golden hues of harvest, every bottle tells the story of Virginia’s rich terroir and dedicated winemakers.
