But experts said consumers do not have to fear empty shelves, and that the flaws in Kartoffeln – a staple in the German diet – are purely cosmetic and do not impact the quality of the food.
Currently, customers in supermarkets have to pay around 84 cents per kg for potatoes in small packages, whereas the price per kg a year ago was 55 cents.
Christoph Hambloch, analyst at the Agricultural Market Information Service (AMI) in Bonn, reported the latest cost increase on Monday, and warned there could be further price hikes in spring.
Consumers should also be prepared for more potatoes that are not completely perfect in appearance. During years with better harvests, products with 'beauty blemishes' wouldn’t be sent to supermarkets to be sold.
But in view of the current shortage, there are currently more potatoes with dark spots and other blemishes finding their way onto shop shelves. Hambloch explained, however, that these are purely optical defects which have no influence on how the food tastes.
As we reported earlier this year, supermarkets, including Rewe and its sister shop Penny, agreed to buy more produce with 'beauty errors' due to the problems faced by the agriculture industry this year.
However despite there being around 3 million tons fewer potatoes in the harvest this year compared to last year, there won’t be a shortage, according to experts.
It just means that there will be reduced potato exports and increased imports, especially in the first part of next year.
Potato farmers who have reaped a significant harvest despite the drought could benefit from selling to supermarket vendors at significantly higher prices. Producer prices for selling potatoes have more than doubled from €10 per 100 kg to €25 to €26
Problems could arise with farmers who had already marketed their harvest in advance at fixed prices, Hambloch said. The situation may also affect others in the food industry, such as peeling companies, particularly in eastern Germany.
The German association of fruit, vegetable and potato processing industry (BOGK) also raised concerns over the harvest, saying it reached a historical low of 8.7 million tons. They added that 2020's crop will be affected in a negative way because the seed potatoes, especially for the early crop potatoes, will not be sufficiently available.
The dry spring and summer has caused huge problems for Germany, resulting in farmers’ crops being damaged and extremely low water levels.
In August Germany's Agriculture Ministry agreed to compensate farmers whose businesses were threatened by one of the worst droughts in years.
Meanwhile, months of drought left water levels on Germany's Rhine river at a record low, exposing a World War II bomb and forcing ship operators to halt services to prevent vessels from running aground.
