At the heart of RPM Bakehouse's philosophy lies the art of crafting sourdough bread – a traditional loaf made from naturally fermented dough, distinguished by its rich flavor, crispy crust, and airy texture. This bread is created through a slow fermentation process, allowing deep aromas and a unique dough structure to develop.

For its production, heirloom grains grown in Ontario are used, contributing not only to its authentic taste but also to its nutritional value. RPM Bakehouse takes pride in using natural fermentation methods without industrial yeast, relying solely on wild cultures of microorganisms that give the dough a mild tang and extend its freshness.

Each loaf of this bread is hand-shaped, carefully baked to perfection, and represents a blend of tradition and artisanal craftsmanship.
