Hamburg’s consumer advocates are suing Mondelez in Bremen over Milka bars shrinking from 100g to 90g. They call it unfair competition and a Mogelpackung, arguing shoppers buy Milka in the familiar packaging for years and assume the content didn’t change, but now get less for roughly the same or higher price—classic shrinkflation. The packaging and design look the same, while the bar is about a millimeter thinner, and a clear note about the reduced content is hard to spot and often blocked by display cartons. They want explicit, visible warnings on packaging and government rules to curb shrinkflation, including a requirement that packaging size reflect content for at least six months.

Mondelez Germany says the new weight is clearly listed on the pack and that customers were informed via social media, noting rising supply-chain and ingredient costs driving price adjustments. They insist changes are reported and the quality remains unchanged in the affected ranges.

Advocates point to a broader pattern of deceptive packaging and skimpflation, continuing to catalog complaints. Bottom line: legal contest, consumer anger, and calls for tighter labeling and packaging rules.
