Fairy tale or real life:
Once up on a time there was a farmer in the Netherlands with a great idea. Milking a cow and package the milk of this cow straight at the farm into a bottle. Sell this milk nationwide and connect the consumer to the cow. So pure and fresh that even you will see a creamy topping on top the bottle with a unique real taste of milk.
So milk from Berta 55 is really milk from Berta 55.
