Organic Sourdough Starter
Try our Organic Sourdough Starter, taken directly from a mature culture that has been maintained for over 30 years and fed using organic flour.
PLEASE NOTE
Your sourdough starter is a live, active culture. During transit it may continue to ferment and, in some cases, can expand enough to escape from the pot and into the sealed bag. If this happens, don’t worry, it is completely normal and does not affect the quality of the starter.
Simply scrape any starter from inside the sterile bag back into a clean container. You only need a small amount of healthy starter to get it going again, and once fed according to the instructions, it will quickly become active and ready to use.
Thank you for understanding that live cultures can sometimes be a little enthusiastic on their journey!
This active live sourdough starter is taken directly from a mature culture that has been maintained for over 30 years and nourished using organic flour. Fully established and regularly fed, it provides a reliable foundation for naturally leavened baking.
Unlike dehydrated starter, this culture arrives alive and fermenting. With a feed on arrival and a short adjustment period, it will be ready to bake with quickly and consistently.
The culture produces balanced acidity and strong fermentation activity, making it suitable for a wide range of naturally leavened breads, pizza dough, focaccia and enriched recipes.
A practical choice for bakers looking to begin with an established organic starter without the time and uncertainty of building one from scratch.
