Ishpatina Ridge Dehydrated Sourdough Starter

Sourdough that began at the summit of Ontario’s highest point
15g dehydrated | Makes 1 sourdough starter | Made in Canada

Bring the spirit of Ontario's remote wilderness into your kitchen with sourdough that began at the summit of Ishpatina Ridge, Ontario’s highest point.

This sourdough was started on August 24, 2025, during a backcountry hike to the historic fire tower at the top of Ishpatina Ridge. At over 690 metres above sea level, surrounded by boreal forest, granite ridges, and beautiful lakes, this is as wild and rugged as bread gets. Read the trip report from the hike to learn more about this beautiful backcountry destination.

Each dehydrated starter contains the strains of wild yeast that were naturally present in the mountain air on top of Ishpatina Ridge the day this sourdough was started. This sourdough was started under native shrubs and trees at the summit and nourished with Ontario-grown flour to create a vibrant sourdough starter that you can bring into your kitchen to share a unique and wild taste of Ontario with your friends and family. This is real backcountry bread, and there's nothing else like it. 

Dehydrated for easy travel and long shelf life, each 15g pouch contains a living culture of native wild yeast and lactobacillus, ready to be revived with just flour and water. Full instructions available here.
