The story of a crispy chip

The adventure begins in 2015

Mikael Cannier creator of the company and professional cook (10 years).

I created the Crousty’Breizh (buckwheat crisps) by noticing that there were few salty biscuits with a real Breton identity for the aperitif!!!

I worked on the recipe in my kitchen for almost a year before going to market in 2015. I started from scratch!

Following the success of sales in the markets, I started door-to-door (delicatessens, wine shops, cheese shops, greengrocers, etc.) with my traveling companion, my van filled with boxes of crisps!

Today, we are a team of 8 people, we make more than 2 tons of chips per week in an artisanal way in our workshops located in Retiers near Rennes.

A beautiful crispy adventure!!!

Crousty’Breizh in the press


Buckwheat, Fagopyrum esculentum Moench, is a species of annual flowering plants of the Polygonaceae family, cultivated for its seeds intended for human and animal consumption.

Despite its common name of buckwheat, buckwheat is not a species of the genus Triticum (a genus grouping together varieties of wheat), nor even a species of grasses. It is gluten-free, which makes it difficult to use pure in breadmaking (black bread) or for making pasta. Buckwheat is considered a cereal, sometimes it is called a pseudo-cereal4.

It is known by various common names: buckwheat, buckwheat knotweed, buckwheat, barbarism wheat, bucail or bucaille, carabin, but also black wheat in certain sources of the 16th century. (Wikipedia)
