What Happens in the Vineyard After the Grapes Are Picked
As the excitement of harvest winds down and the last clusters of grapes are gathered, many imagine that vineyard life slows to a halt. In reality, this is one of the most fascinating times of year. The work doesn’t stop once the grapes are off the vine—nature and vineyard crews begin an essential cycle of rest, renewal, and preparation for the next vintage.
At Corteza Vineyards in Knightsen, where we practice organic viticulture and work in harmony with the land, every season plays an important role in producing exceptional wine grapes. Here’s what happens after harvest—and when the next big vineyard task, pruning, begins.
1. Post-Harvest: The Vines Begin to Rest
After the fruit is harvested, the vines don’t go dormant right away. For several weeks, the leaves continue to photosynthesize, storing nutrients and carbohydrates in the roots and trunks. This stored energy will sustain the vine through winter and fuel early growth in spring.
During this time, vineyard teams focus on soil health—returning organic matter to the earth, composting grape pomace, and sometimes planting cover crops like clover or vetch to prevent erosion and improve soil fertility. It’s all part of maintaining a sustainable ecosystem that ensures the vines thrive year after year.
2. Vineyard Clean-Up and Maintenance
Once the leaves begin to turn golden and fall, the vineyard enters a quieter phase. Crews remove old canes, repair trellises, and tidy up rows to prepare for winter rains. In organic vineyards like Corteza, this is also when we assess vine health and remove any diseased wood to prevent issues in the coming season.
The winery is equally busy during this period. Freshly harvested grapes are now fermenting, aging, and transforming into wine—a process that will continue for months before bottling. The vineyard and winery are deeply connected; both move in rhythm with the seasons.
3. The Dormant Season: Winter Rest
By late November or December, the vines enter dormancy, appearing bare and lifeless above ground. Beneath the soil, however, roots are still active, slowly absorbing nutrients and water. This rest period is essential—it allows the vines to conserve energy and prepare for another year of growth.
Winter rains replenish the soil and restore balance to the vineyard, setting the stage for renewal in the spring.
4. Pruning: The Next Step in the Vineyard Cycle
Pruning typically begins between January and February, depending on the weather and vine conditions. It’s one of the most important tasks of the year. Each cut shapes the future harvest—determining how many buds will produce fruit and guiding the vine’s growth pattern.
At Corteza Vineyards, pruning is done by hand with care and precision. Our goal is to balance vine health with optimal grape quality, ensuring each vintage expresses the unique character of our Knightsen terroir.
From Harvest to Renewal
The period between harvest and pruning may seem quiet, but it’s a vital chapter in the life of the vineyard. Every step—from soil enrichment to winter rest—ensures the vines are strong, balanced, and ready to produce the next beautiful crop of grapes.
At Corteza Vineyards, we believe that great wine begins long before the first bud breaks—it starts with respect for nature’s rhythm, year-round care, and an unwavering passion for the land.
