Pruning for Excellence:
How Winter Decisions Shape Harvest Quality
By: Joseph Geller
As a vineyard manager, pruning is my favorite time of year in the field. The mountain is quiet. The vines stand bare against the winter sky, their energy drawn inward. The pace slows, but the work never stops. Pruning is one of the most influential tasks we perform all year. It sets the stage for everything that follows and shapes the rhythm of the growing season from the very beginning.
At Dynamis Estate Wines, we prune for quality, not quantity. That distinction matters. From day one, we commit to producing the best possible fruit our site can offer, even when that means sacrificing yield. Premium wine starts in the vineyard, and pruning is where that commitment begins. (See pruning in action with our Dynamis Pruning 2025 Video).
Much like winemaking, pruning is equal parts art and science. Each cut is deliberate, shaping the vine to promote balance, health, and longevity. It is an ancient practice that cannot be rushed or mastered overnight. To become a true pruning artist, you do not chase trends or shortcuts. You study and respect the techniques refined by European vignerons over centuries.
The Poussard Method: Protecting the Vine’s Lifeline
On our estate, we practice the Poussard pruning method, also known as soft or sustainable pruning. Developed in the early 20th century by Charentais winemaker Mr. Poussard as an evolution of traditional Guyot pruning, this method preserves sap flow and builds continuous branching structures within the vine. It respects the vine’s natural architecture. The result is beautifully formed heads and spurs designed to endure for decades.
Soft pruning is essential to long-term vine health. The vine’s vascular system functions much like plumbing. Poorly placed cuts can cause dieback, restricting the movement of water and nutrients. Over time, that restriction weakens the vine. By allowing pruning positions to branch progressively rather than stacking cuts on top of one another, we maintain clear sap pathways and ensure each cluster receives what it needs to produce exceptional fruit.
Spur and Cane: Two Systems, One Goal
There are two primary pruning styles, and we utilize both across our estate. Spur pruning, the most widely used method in the industry, involves cutting back spurs to two clear buds along permanent cordons extending from the trunk. Cane pruning, known as Guyot in France, trains a permanent trunk to a head and relies on laying down a new fruiting cane each season, creating a continual renewal cycle.
Each system has advantages. Spur pruning is efficient and requires minimal tie-down work in spring, though it often demands significant shoot thinning later in the season. Cane pruning requires more time and precision during winter, including careful tie-down, but shoot thinning is typically quicker and more controlled. Spur-pruned vineyards can be planted at wider spacing, reducing initial planting costs. Cane-pruned vineyards require closer spacing and greater upfront investment, but they offer structural and health benefits that become more apparent as vines mature.
One of the greatest advantages of cane pruning is the annual renewal of fruiting wood, which significantly reduces overwintering fungal pressure. For this reason, all new vineyard installations at Dynamis are transitioning from 6-foot spaced spur-pruned vines to 4.5-foot spaced cane-pruned vines. This decision reflects our long-term view of vine health and wine quality.
Decisions Made in Winter
In the end, pruning is more than a seasonal task. It is a discipline that demands intention and foresight. By the time harvest arrives, many of the season’s outcomes were already influenced by the decisions made in winter. Every cut reflects our commitment to vine longevity and to the quality in every bottle that follows. At Dynamis Estate Wines, excellence begins long before budbreak.
