Stiff Sourdough Starter (10 g) – Fresh, Active, and Ready to Bake
Stiff Sourdough Starter (40% Hydration)
This is the starter we trust to get to your door alive and kicking. It is strong, steady, and designed for bakers who care about reliability. Each portion is hand-mixed with certified organic Canadian flour and maintained at 40 percent hydration to keep it resilient during shipping. It arrives active and ready to feed. You can use it to mix your dough the very same day.
We prepare and pack each starter fresh on Mondays and ship express so it arrives in time for weekend baking. Your culture is delivered in a 45 ml screw-top test tube. Once empty, you can reuse the tube to store a spare portion of your starter or to track dough fermentation with the aliquot method.

Sourdough Starter FAQ
What is a sourdough starter?
A sourdough starter is a living culture of wild yeast and bacteria that ferments flour and water. It’s not the dough itself — it’s what you use to leaven your bread. You add a portion of your active starter to your flour, water, and salt to make dough. It replaces commercial yeast, giving your bread rise, flavour, and character through natural fermentation.
Is the starter ready to use when it arrives?
Yes. This is a live, stiff sourdough starter that ships fresh every Monday. Once it arrives, feed it once using the included instructions. You can mix dough the same day.
How should I store the starter?
Store your starter in the fridge, either in the test tube or a small jar. Feed it weekly to keep it healthy and active.
How do I use the test tube to track fermentation?
Once empty, reuse the tube to track bulk fermentation. Add 10–12 g of mixed dough and mark the starting level. When it rises to the top, your dough is ready to shape.
