The little story of a big biscuit factory

In 1955, in a modest shop in LaTrinité-sur-Mer, Lucien Petit stumbled upon a new biscuit recipe: a thin rolled biscuit in the shape of a cigarette,made with pure butter.

The success of this product led the whole family into a challenging yet rewarding adventure: the creation of La Trinitaine biscuit factory.

The story of La Trinitaine, an iconic Breton heritage brand, revolves around a family, a location, and a specific area of expertise: that of biscuit-making. Passed down through the generations, this expertise draws on original recipes, accompanied by a daring, open-minded approach to ensure continued innovation and the development of new products.

Driven by its origins as a small store, La Trinitaine today not only produces over 11,500 tonnes of biscuits a year, but also runs a network of 46 shops in France.

La Trinitaine is one of the last French biscuit-makers of this size to have retained its independence.
