We bake large loaves to better maintain the bread's internal moisture and give it a longer life. This is only possible by baking with sourdough.
Choosing stone milling ensures a full-body intact flour, sifted only later to remove the outer, less digestible cruscal parts. These flours keep all the nutrients of the grain intact.
Sourdough is a living organism, a yeast that brings the values of biodiversity into the loaf, which allows for long shelf life and greater digestibility.
Gluten is not a molecule found in wheat, but is formed when flour comes into contact with water and energy (the dough): then glutenin and gliadin, two proteins in wheat, produce gluten. There are grains that have these proteins to a lesser extent than others, and therefore develop a less tenacious gluten, among them the territorial grains we grow. There are also processing conditions that allow the strength of gluten to be attenuated, such as the PH of the dough, in which case it is the sourdough that helps. The body recognizes gluten as an allergen only when its tenacity is excessive; sourdough, the use of gentle grain flours, and careful processing ensure that this does not happen.
We commonly speak of ancient grains referring to species that have evolved over millennia of cereal farming, adapted to different human, cultural and environmental conditions, whereas it would be more correct to circumscribe the definition to the progenitors of wheat. The grains we predominantly grow and process are local varieties of soft and hard wheat, minor grains such as rye, and cereal mixtures.
Mixture is an agronomic practice of sowing different varieties of seeds of the same species in a field in order to obtain, over the years, a diverse, dynamic grain population capable of adapting to even sudden changes in the environment.
