German chocolate company Stollwerck is to be taken over by Barry Callebaut of Switzerland. Barry Callebaut has received approval from competition authorities to buy Stollwerck for SFr256m (US$169.9m), after announcing late April that it intended to do so. The deal brings brands such as Alpia, Gubor and Sarotti into the Barry Callebaut fold and gives it a stronger presence in Germany, where Stollwerck generates some 60% of its sales, reported Dow Jones.
