Ninety million vines, a single node
In the heart of Friuli Venezia Giulia, a single company produces 90 million grafted vines every year. This is not just any agricultural operation; it’s the material basis on which the entire global wine-making system rests. Vivai Cooperativi Rauscedo (VCR), based in Rauscedo, not only supplies 60% of Italian vines, but also holds a 25% share of those grown on every continent. This concentration is not just an industrial factor; it’s a critical point in the global genetic flow.
The annual production of grafted vines, as reported by WineFrontiers, is not an isolated metric: it represents the mandatory step for planting over one-third of new vineyards worldwide. Each plant that leaves VCR’s facilities carries with it a specific genetic combination, selected not for diversity but for yield, resistance, and market demand. The process is highly standardized: chosen grape varieties are grafted onto roots from controlled clones, rigorously sanitized in laboratories operating according to international quality protocols.
The Fragility of the Model
The global genetic infrastructure is subject to an invisible structural constraint: dependence on a few production centers. According to a study published in OENO One, rootstocks – the roots on which vines are grafted – are not only elements of resistance to Phylloxera, but directly influence the mineral content of the plant and its growth. The choice of rootstock determines adaptation to arid, calcareous or saline soils, but also productivity and the quality of the final wine.
The concentration of this choice in a single network – VCR, which manages 430 different clones among the main grape varieties worldwide – creates a systemic vulnerability. If a climate event or pathogen affects the common genetic base, the impact spreads exponentially. As highlighted by Ives Conference Series 2026, the decline in research in the field of rootstocks in recent decades has drastically reduced the available diversity: today less than 10% of the root varieties used have been developed after 1950. The system has become an architecture of repetition, not of innovation.
The genetic node as a strategic infrastructure
Analysis of the global viticulture sector reveals a contradiction: while the industry presents itself as an ecosystem of small businesses, local traditions, and distinct terroirs, the raw material is controlled by a centralized structure. The wine that is sold in bottles – often with labels celebrating geographical origin or ancient grape varieties – comes from a process of selection and propagation managed by a single Italian cooperative.
The gap lies in the fact that the public narrative of wine as an artisanal product, linked to terroir and local history, contrasts with the actual infrastructure: a standardized production chain controlled by a single entity. Quality is no longer determined by the soil or tradition, but by the efficiency of the genetic system that feeds the field.
The Future as a Risk-Based Choice
The current model depends on an extremely high production capacity – 90 million grapevines per year – but is unable to handle structural changes. The resilience of the global vineyard system does not lie in diversity, but in the efficiency of the production chain. If an external event (a new pathogen, a logistical crisis or accelerated climate change) affects the common genetic base, the entire system is at risk of collapse.
Control over plant material is no longer just a technical aspect: it is a strategic factor for food security. The ability to produce wine – one of the few crops with high cultural and commercial value – depends on a critical node, located in a single region of Italy. This concentration is not inevitable; it is the result of technological, economic and political choices that have prioritized scale over diversity.
