From Wednesday 14 September around 9 am, the oven of the Hermitage is warmed up for the first batch of the heritage bread on Saturday 17 around 12 pm. The batch then follows in front of the public to which the volunteers present the phases of bread making. The local residents' dough is also baked and the bread is offered for public tasting. At the end of the event, the residual heat is used to cook a pizza at the end of the event, the ingredients of which are brought by the inhabitants who take part in a talk on the theme "Sustainable heritage" This year, recalling the sustainable Pain du Vexin at Croix Pattée presented in 2008.
This tasting of bread baked in an oven at the beginning of the nineteenth century is, on the other hand, the occasion to present to the public and to the officials a restrospective mural of the wine-making activity of the district and the paintings of impressionists of the district like C. Pissarro, P. Cézanne and post-impressionist like G. Loiseau.
