Cailler of Switzerland is one of the largest Swiss chocolate manufacturers and claims to be the oldest brand in the chocolate business. Cailler has been producing chocolate since 1819 (in Vevey) and since 1898 in Broc. Cailler was the first manufacturer of chocolate slabs. Cailler has been part of the Nestlé group since 1929 but still operates largely independently.

Broc and the chocolate factory area are clearly part of a modern industry. The main factory building shows industrial architectural lines from the early nineteenth century but has been sympathetically enlarged in more modern times.  Railway lines ensure an environmentally friendly way to transport raw materials to the factory and chocolate to the market. Milk is mostly sourced locally.
