Sourdough Starter - 30 Year Mature Culture Dehydrated
This dehydrated sourdough starter is made from a mature culture that has been actively maintained for over 30 years. Carefully dried to preserve viability, it offers a practical way to store, ship, and share a proven starter without refrigeration.
Once rehydrated and fed, the culture becomes active again, ready to leaven bread in the traditional way. It develops the balanced acidity, fermentation strength, and flavour complexity expected from a well-established starter.
Suitable for both new and experienced bakers, this is a reliable foundation for naturally leavened bread — from rustic country loaves to enriched doughs
