Question

Why did switzerland, a landlocked country which never held any colonies let alone one where coco beans grow, become so famous for chocolate?

Answer 1

The cows produce a more dense less aerated milk due to the fact they are at altitude and the milk is officially known as alpine milk. These two main ingredients are a big part of the reason why Switzerland is famous for chocolate

Answer 2

The milk is different due to the altitude.  The high altitude makes the milk more dense.   It is known as 'Alpine Milk'  This makes the chocolate taste different and wildly popular around the world
