EU-4 potato crop set to fall by almost a quarter

The potato harvest across the EU-4, Europe’s key region for processing potatoes, is set to fall sharply this season. DCA Market Intelligence estimates combined production in the Netherlands, Belgium, France and Germany at around 20.8 million tonnes, almost a quarter below last season (-23.7%).The EU-4 forms the heart of the European processing potato industry. A significant share of the potatoes grown in these four countries is processed into frozen French fries and other potato products for European and international markets.The smaller crop is the result of both reduced planted area and lower yields. Growers cut processing potato acreage substantially in several countries following the large 2025 harvest and challenging conditions in the frozen fries export market. Dry and hot weather during the 2026 growing season subsequently reduced yields.In the Netherlands, processing potato acreage fell by around 15%, while DCA Market Intelligence estimates average yields to be approximately 14% lower. Belgium recorded an acreage reduction of around 16.6%, while planted area declined by approximately 10% in France and 11% in Germany.Core European production region under pressureThe reduction across all four countries makes this more than a national production issue. Together, the Netherlands, Belgium, France and Germany represent the main production base supplying Europe’s large frozen potato processing industry.DCA Market Intelligence monitors this market continuously and publishes the DCA EU-4 Potato Index, a weekly benchmark for the physical processing potato market across the four countries. DCA also compiles the weekly DCA Frozen Fries Index, which tracks developments in the cost base of frozen French fries.Despite the significantly smaller crop, the impact on processors and consumers is more complex than the production figures alone suggest.Much of the crop already contractedA large part of the 2026 potato crop was contracted between growers and processors months before harvesting began. During this stage of the season, factories are largely supplied with potatoes delivered directly from the field, while activity in the open market remains limited.Contract prices for the 2026 crop were reduced following the large 2025 harvest and weaker European frozen fries exports. For early-season deliveries, contract prices are around 25% below last year’s levels. For potatoes scheduled for delivery later in the storage season, prices were generally fixed around 15% to 17% lower.These contracts remain an important factor in the market, even as the physical availability of potatoes has tightened considerably. This means that the effects of the smaller harvest are not immediately reflected in the prices paid by processors for all of their raw material.Potato price only part of the cost of friesChanges in potato prices also do not translate directly into the retail price of frozen French fries. Potatoes are only one part of the final production cost. Processing, energy, frying oil, labour, packaging, transport, cold storage and distribution all contribute to the price of the finished product.This works in both directions. Lower contract prices for potatoes do not automatically result in substantially cheaper fries, while higher prices for the limited volumes traded on the open market do not necessarily lead to an equivalent increase in retail prices.For growers, however, the effect of the smaller harvest is much more direct. They are harvesting significantly fewer tonnes per hectare this year, while a large share of production was contracted earlier at lower prices. Higher prices for the relatively small volume still available on the open market therefore do not automatically compensate for the loss in yield.The 2026 season therefore presents a clear contrast within the European potato supply chain. Substantially lower production across the EU-4 is having an immediate impact on growers and raw material availability, while the effect further down the chain is moderated by existing contracts and the broader cost structure of frozen potato products.
