Beyond the winter pruning that sculpts the vine, and the numerous spring and summer tasks to guide its growth, another essential manual job ensures the longevity and good health of the vineyard: sécaillage (trellis maintenance). Less known to the general public, this constant upkeep of the vineyard's infrastructure is nevertheless crucial to guarantee robust vines and quality production year after year.

Definition and fundamental role of sécaillage

Sécaillage consists mainly of checking and re-tensioning the trellis wires, which are essential for keeping the vegetation upright and ideally exposing the leaves and bunches to the sun. Over time, bad weather, variations in tension due to vine growth, or the passage of machinery can cause these wires to slacken or even break. A faulty trellis system can lead to vines falling over and poor aeration, thereby encouraging diseases and reducing the efficiency of photosynthesis.

A clear agronomic objective: supporting growth and quality

The main agronomic objective of sécaillage is to offer optimal support to the vine, so that it can express its full potential. By ensuring the structure is well maintained, sécaillage facilitates the penetration of sunlight and the circulation of air within the canopy. This controlled aeration and sun exposure are essential to prevent the appearance of fungal diseases such as mildew or powdery mildew, and to promote an even ripening of the berries. This directly contributes to the future quality of the wines.

The key moment for sécaillage: a winter and spring task

It is a demanding manual job, often carried out in winter or early spring, which requires observation, strength, and great meticulousness. Every wire is inspected, every post is checked, ensuring that the vine's framework is in perfect condition to face the new season. It is also the opportunity to replace damaged posts, which support the entire structure.

The practical steps of trellis maintenance

Sécaillage takes place in several stages. It begins with a meticulous visual inspection of each row of vines to identify slackened or broken wires, and damaged or missing posts. Next, the wires are re-tensioned manually using special pliers or wire strainers. Broken wires are repaired by tying them or replacing them. Finally, defective posts are replaced and the insulators are checked to ensure the wires are securely attached. This work is often integrated into the first stages of vineyard work in the spring, after pruning. It is part of the broader framework of essential tasks such as clearing the vine base (mandronner), thereby ensuring the vine is well-supported and the yield is consistent.

The essential equipment for effective sécaillage

To carry out effective sécaillage, little equipment is required, but it must be suitable and of good quality. Tying pliers, wire strainers, galvanised wire of various diameters for replacements, and of course, new wooden or metal posts are generally used. Sturdy gloves are also essential to protect the winegrower's hands. For a precise and effortless cut, many opt for the efficiency of secateurs.

The Château Cazebonne approach: when vineyard maintenance fuels the rebirth of grape varieties

At Château Cazebonne, this commitment to the meticulous maintenance of the vineyard takes on a special dimension. By replanting the forgotten and historic grape varieties of Bordeaux, these varieties that had been abandoned, we are forging the future of wine whilst reconnecting with its past. Sécaillage and all manual work are no longer just a routine, but fundamental pillars to best support the growth of these young, sometimes delicate vines, and ensure their harmonious integration within our terroir. You can learn more about vine propping (calage) to understand the importance of these practices.

This long-term work, a true agronomic challenge, is made possible thanks to the enthusiasm and unwavering support of a community of enlightened wine lovers. Your passion for our wines and your commitment are the driving force that allows us to pursue this adventure and bring back to life grape varieties that have so much to offer to the typicity of Bordeaux wines. If you wish to deepen your knowledge of the fascinating history of Bordeaux grape varieties and understand the importance of this approach, we invite you to download the digital version of the book "Bordeaux, une histoire de cépages" or test your knowledge with our oenological quizzes.
