The IWSR (International Wine and Spirit Research) has published its verdict. And those who know how to read data — not as a succession of statistics, but as an X-ray of forces in motion — will understand that this forecast does not merely announce a contraction. It announces a war.
The numbers, first. Global wine consumption fell five percent in 2025 alone — nearly double what the OIV had estimated in its annual report. And between now and 2035, the IWSR projects a further 14 percent decline in worldwide wine consumption, drawn from an analysis spanning 160 countries. The overall market for alcoholic beverages contracted by two percent. Even spirits and beer, historically more resilient, are under pressure. The only category that continues to grow, with the enviable confidence of a new arrival disrupting an established order, is RTD — Ready-to-Drink beverages.
The data also reveals another truth, one that is geopolitical as much as it is commercial: the recomposition of the world wine map is accelerating. China, the United States, Japan, Germany and the United Kingdom — in other words, five of the most coveted markets in the global wine industry — are all shrinking simultaneously. India, Colombia, Vietnam and Mexico, meanwhile, are growing. India will surpass the United States as the second-largest alcohol market in the world by 2032, behind China alone. Understand what that means: 1.4 billion people, a rapidly expanding middle class, a wine consumption starting from a very low base. These are not emerging markets. They are the future battlefield.
But let us not be distracted by the geography. The essential truth buried in these figures is more dangerous — and more urgent — than any market mapping exercise. When a pie shrinks, it is not the shrinkage itself that kills you. It is the fight for every remaining slice.
History is littered with examples of industries that contracted and, in doing so, triggered wars of an intensity that growth had never required. Oil in the 1980s. Steel in the 2000s. The airline industry, endlessly. In each case, the reaction to the contraction was not resignation — it was escalation. Escalation in promotional intensity. In innovation. In distribution muscle. In price aggression. In brand investment. The weakest disappeared. The most cunning survived. The strongest devoured.
The global wine industry is about to enter this phase. It is not tomorrow. It is already happening.
In a contracting market, market share becomes zero-sum. What one producer gains, another loses. There is no longer any growth tide to lift all boats. This brutal, cold arithmetic transforms every sales call into a battle, every shelf facing into a contested territory, every consumer touchpoint into a strategic objective. The language of business strategy is not sufficient to describe what lies ahead. The language of war is more precise.
What form will this war take? It will be fought simultaneously on several fronts, with unequal weapons.
The commercial front will be the most immediately visible. The marketing and communications front will be decisive in the medium term. The innovation front, finally, will separate the visionary from the merely competent. Sun Tzu wrote in The Art of War that the supreme general wins without fighting. In business, this translates into a single imperative: position yourself so advantageously, so early, so precisely, that when the battle intensifies, the outcome is already decided. The estates and négociants that invested in brand, distribution and innovation a decade ago are already better armed than those who are beginning to ask the question today. But the race is not over.
The IWSR forecast is not a death sentence. It is a call to arms. The global wine market is contracting. The competition for every bottle sold, every glass poured, every consumer won will only intensify. In a shrinking market, there is no such thing as a passive strategy. There is no such thing as maintaining the status quo. There is only attack, or retreat. Choose your side.
