Turns out German farmers grew too much potatoes last year, so now all the extra potatoes have to be consumed (the alternative is just burning them for biodiesel).
This means free potatoes for everyone in Berlin!
They accept applications for batches over 1 ton until Monday; and also on Thursday and Friday there will be multiple distribution points across Berlin for picking up smaller amounts for personal consumption, measured in kilos.
