At that time, chocolate was essentially considered as a tonic rather than a delicacy, and it was generally dissolved in water or milk.

[3] The factory allowed Cailler to produce solid and affordable chocolate, that was moulded into tablets or small blocks.

[1][8] François-Louis Cailler died in 1852 and his wife Louise-Albertine continued to run the company along with their sons, Auguste and Alexandre.

[9] In the early 1890s, following the development of the conching process, Cailler began manufacturing a new type of chocolate specially made for eating.

[2] The following year, the dedicated hydroelectrical plant on the Jogne was commissioned, allowing the electrification of the entire village of Broc.

The waters of the Jogne had been diverted by means of a one-kilometre-long tunnel, allowing an electrical production of 2000 HP through a 44-metre fall.

[11] In 1912, was inaugurated the Bulle-Broc-Fabrique railway, which replaced horse-drawn goods convoys to Bulle, the major town in the area.

[1] A foreman who previously worked for Daniel Peter helped Cailler develop this new type of chocolate, which would become particularly successful.

[15] Until 1951, Nestlé used all three names Peter Cailler Kohler for its chocolates, which were then commonly referred to as the PCK brand.

[22] Cailler produces a wide range of 100 g and 200 g chocolate tablets, essentially milk but also dark and white.
