A 130-Year-Old Heirloom Starter

At the heart of Summit Sourdough is a 130-year-old family heirloom sourdough starter, carefully maintained for its strength, reliability, and consistent performance.

Trusted by home bakers across Canada, the United States, and beyond, it is known for its exceptional activity and its ability to produce beautiful, consistent results. It delivers strong fermentation, reliable rise, impressive oven spring, and a well-developed crumb — the qualities that define truly great sourdough bread.

Why Our Starter Is Different

Not all sourdough starters perform the same — and the difference becomes clear the moment you begin baking.

Our heirloom sourdough starter is a mature, well-established culture that has developed the strength and stability needed to produce consistent, reliable results. Unlike newer or less active starters, it responds predictably, rises with confidence, and maintains its performance over time.

For many home bakers, this means less frustration and more success — a starter that works with you, not against you.

My Sourdough Story

My journey with sourdough began out of necessity after being diagnosed with Crohn’s Disease. I was searching for a way to enjoy the foods I loved again while learning more about long fermentation and traditional sourdough baking.

For years, I struggled with an inconsistent homemade starter that never delivered the results. When I began working with our family heirloom culture, the difference was immediate — stronger rise, better activity, better texture, more reliable bakes.

More Than a Starter

Summit Sourdough is built around the idea that great bread comes from both a strong foundation and the right tools. 

Alongside our dehydrated sourdough starter, we offer a curated collection of baking tools and reusable kitchen products designed to support every stage of the sourdough process.

From brotform proofing baskets to  our made in Canada reusable bread bags, bowl covers, and baking tools, each product is created and selected to improve your workflow, reduce waste, and elevate your baking experience.
