Did Cadbury Roses, Heroes and Twirl pouches (UK) shrink?

Source and evidence

Against official inflation: ONS CPI (UK) “sugar, jam, honey, syrups, chocolate and confectionery” changed +10.2% (12 months to Dec 2025). The size cut alone raises the price per gram by +11.1% if the shelf price stayed the same (the source recorded no prices). Every case is compared the same way in the ShrinkRadar Index.

What the source says

“…Mondelez is among those that opted to tweak pack size instead. Pouches of Roses, Heroes and Twirl are the latest to succumb to shrinkflation, reduced in size by 10% ahead of Christmas from 300g to 270g. Others chose reformulation.”
