Viticultural agronomic consultant

Everything you need to know about viticultural agronomic consultants

What is a viticultural agronomic consultant?

A viticultural agronomic consultant is an independent expert specialising in the technical management of vineyards. They work with winegrowers, châteaux, cooperatives and wine groups to optimise the management of their plots, improve the quality of grapes produced and adapt viticultural practices to current challenges: climate change, reduction of chemical inputs, organic certification and biodiversity improvement. Their external perspective and technical expertise enable wine estates to progress and resolve complex problems.

The agronomic consultant differs from the oenologist through their area of intervention focused on the vineyard rather than the cellar. They diagnose soil deficiencies, identify diseases and pests, advise on treatments, prescribe appropriate pruning and accompany organic conversion. Their expertise covers pedology, vine physiology, phytopathology, fertilisation and increasingly digital precision viticulture.

History

Agronomic advice in viticulture has existed as long as vines have been cultivated, but it was long the domain of cooperative technicians, agricultural chamber agents and representatives of phytosanitary product companies. Independent agronomic consultation, billed by time spent, truly professionalised from the 1980s-1990s, with the quality upgrade of French and international vineyards.

The downy and powdery mildew crisis in the 1990s, then the first pesticide restrictions in the 2000s, pushed winemakers to seek expert advice to rationalise their treatments. The rise of the organic and biodynamic movement from the 2000s created strong demand for consultants capable of accompanying conversions.

Today, precision viticulture and digital tools (satellite imagery, drones, connected sensors) are opening new fields of expertise for viticultural agronomic consultants. The ability to interpret complex data and translate it into practical recommendations has become a differentiating competence.

The profession day to day

The viticultural agronomic consultant spends a large part of their time in the vineyards. They make regular visits to clients to observe the state of the vineyard, detect phytosanitary problems early, assess the vigour and load of the vines, and adapt advice in real time according to the campaign's climatic conditions.

Soil and plant diagnosis is one of their central activities. Soil and foliar analyses, water status observations, yield potential assessment: these diagnostics enable the establishment of a fertilisation, irrigation and vine management plan adapted to each plot. Detailed knowledge of different terroirs and their interactions with grape varieties is a rare and precious expertise.

The drafting of prescription books and supporting viticultural teams in applying recommendations are essential dimensions of the advisory role. A good consultant does not simply diagnose and prescribe: they train, explain, convince and measure results to continually refine their recommendations.

Viticultural agronomic consulting in figures

According to data from the Chambre d'Agriculture de France and the IFV:

Over 2,000 independent or employed viticultural advisors active in France — Chambre d'Agriculture, 2022

Over 50% of French wine estates over 20 ha use external advice — IFV

Organic conversion is the primary reason for consulting a viticultural agronomic consultant — IFV, 2022

Precision viticulture consulting is the fastest-growing segment of viticultural advice — IFV

Bordeaux and Burgundy Grand Crus mostly use external agronomic consultants — CIVB

Contemporary challenges

The viticultural agronomic consultant is at the heart of the agroecological transition of the vineyard. Growing regulatory pressure on phytosanitary products, combined with consumer demand for more environmentally respectful wines, creates strong demand for their expertise. Accompanying winemakers in reducing inputs while maintaining quality and profitability is the central challenge of their profession.

The mastery of digital tools has become indispensable. Consultants who can interpret satellite imagery data, exploit disease forecasting models and configure connected sensors have a considerable competitive advantage. Precision viticulture enables optimisation of interventions at the plot scale or even intra-plot zones, generating significant savings in inputs and fuel.

Finally, the internationalisation of viticultural consulting is a strong trend. French consultants work in China, India, Brazil and emerging countries developing their vineyards. This exported expertise valorises French viticultural know-how at a global scale and opens new high-added-value markets.
