European potato prices reach €240 a tonne after sharp yield losses
Processing potato prices in Germany have risen to about €240 per tonne from roughly €30 a year earlier as heat and lower acreage cut European production. Germany, France, Belgium and the Netherlands are expected to harvest around 20.7 million tonnes, with processors, retailers and buyers facing tighter supplies.
Heat and lower acreage reduce the crop
European potato markets are tightening after severe weather and reduced planting pushed yields down by as much as 20% in parts of the region. Processing potatoes in Germany are trading at around €240 per tonne, with some transactions reaching €250, compared with roughly €30 per tonne a year earlier, according to ad-hoc-news.de.
The sharp reversal follows five consecutive heatwaves, which Expana analyst Craig Elliott identified as the driver of the shift from a record harvest to a record low. The pressure is concentrated in Germany, France, Belgium and the Netherlands, four major producers that also form the core supply base for Europe’s potato-processing industry.
The North-Western European Potato Growers, or NEPG, estimates combined production in those four countries at about 20.7 million tonnes. That compares with 27.3 million to 27.75 million tonnes in 2025. ECIU gives a lower forecast range of 19.5 million to 20.5 million tonnes.
Germany records the largest deficit
According to ECIU’s analysis dated 17 September 2026, Germany, France, Belgium and the Netherlands are producing about 3.1 million tonnes less than their five-year average. Including the United Kingdom, the shortfall exceeds 3.5 million tonnes. Germany has the largest absolute deficit at 1.13 million tonnes.
NEPG estimates that the planted area in the four continental countries fell by 13.7%, from 604,000 hectares to 521,500 hectares. Average yield is put at around 40.5 tonnes per hectare, approximately 14% below both the previous year and the five-year average. Its country breakdown assigns 7.55 million tonnes to Germany, 6.49 million tonnes to France, 3.43 million tonnes to Belgium and 3.23 million tonnes to the Netherlands.
For France, the estimated crop is the smallest in 30 years apart from 2022. The contraction has also lifted fresh-market prices: table potatoes opened the season at €270-€280 per tonne, against about €150 in the previous period. In France, table potato prices increased from €310 to €520 per tonne.
Processors and retailers face tighter availability
ECIU analyst T. Lancaster estimates total financial damage at €498 million to €818 million. Of that amount, €405 million to €622 million relates to the European Union, while losses in the United Kingdom are estimated at £80 million to £169 million. Industry observers expect available stocks to last until around Christmas, increasing the importance of procurement timing and contract coverage for processors and retailers.
The immediate impact will differ across the supply chain. Growers with a saleable crop can benefit from higher prices, but farms suffering major yield losses may have too little volume to offset reduced output. Processors face more expensive raw material and competition for suitable potatoes, while retailers and food-service buyers must manage higher fresh-market prices and potentially tighter availability.
Cross-border sourcing within north-western Europe can redistribute the remaining crop but cannot replace a regional deficit affecting all four principal continental suppliers. The German Farmers’ Association says basic food supplies remain secure, although it warns of below-average harvests across several crops and possible total crop failures in parts of southern Germany. It is seeking measures including EU fertilizer aid, earlier direct payments, a reduction in agricultural diesel tax by the end of November and a tax-free risk reserve.
