2026 Grape Harvest: Drought reduces yields, but excess stock is weighing on the Italian wine market

A paradoxical grape harvest. Because winegrowers, who have always seen the harvest as a source of income, if not wealth, now find themselves almost having to hope for a lower yield. And the drought, which has also affected Italian vineyards, will play a part in reducing production, because, combined with the lack of a significant temperature difference between day and night, it has caused the grapes to dehydrate and the bunches to lose weight. However, the drop in production will be less than would be desirable.

This is the mixed sentiment prevailing amongst Italian wine producers, whilst the grape harvest – which is ahead of schedule – is already well under way. The real problem, in fact, is not production but the market. Italian wine is heading into the 2026 vintage with record levels of unsold stock: according to the Ministry of Agriculture, as at 31 July this year, there were 45.6 million hectolitres of wine and must in Italian cellars (+8.2 per cent compared with 31 July 2025). This quantity is equivalent to having an extra harvest in stock.

The result is an oversupply that is weighing on prices. Last June, Italian DOC bulk wines were priced at an average of 1.57 euros per litre, down 7 per cent on the previous year. The situation was even worse for table wines (-19%). Adding to this already complex picture is the fact that, in the first five months of the year, exports fell by almost 7 per cent (to €3 billion), with exports to the US down 15 per cent.

This is why the prospect of a bumper harvest is viewed with some concern. “We believe there may be a decline compared with last year,” explains Paolo Castelletti, Secretary-General of the Italian Wine Union, “but not on the scale required. Under these conditions, vineyards in Italia are unable to guarantee an income for those who work them. We are talking about an average gross saleable yield of 4–5 thousand euros per hectare, compared with costs that often reach 7 thousand. This is a reality we must acknowledge. Under current market conditions, we in fact consider a harvest of 35–38 million hectolitres to be sustainable – a target that cannot be achieved through improvisation; it requires planning.”

There has been a sign that the wine-producing sector is becoming more aware of the issue. In recent months, many wine consortia with protected designation of origin (PDO) status have reduced the grape-to-wine yield – that is, the limit on the number of quintals of grapes that may be used to produce DOC wine per hectare of vineyard. This decision has been adopted by Brunello di Montalcino (70 quintals per hectare, down 12.5 per cent), Chianti Classico (65 quintals, down 13.3 per cent), Valpolicella (100 quintals, down 16.7 per cent), Soave (130 quintali, -10 per cent), Pinot Grigio delle Venezie (160 quintali, -11.1 per cent), as well as Barbera d’Alba (90 quintali, -10.5 per cent), Asti DOCG (85 quintali, -15 per cent) and, finally, Montepulciano d’Abruzzo and Verdicchio di Jesi, with reductions of -10 per cent and -21.4 per cent respectively. ‘This is an important sign,’ adds Castelletti, ‘which at least demonstrates a growing awareness. But this system has a fundamental flaw. Reducing the yield leads to a decrease in production for that particular DOC but not in overall production, because more grapes can still be produced from that vineyard and then used for IGT or table wines. We need to change the system and transform the yield limit into an absolute production cap, as is the case in France. Otherwise, excess wine will continue to flood the market, driving prices down.”
