ORGANIC CERTIFIED & UKAS LAB TESTED - Our Gloucestershire Rye Sourdough starter culture is certified by the Organic Food Federation and tested by a UKAS accredited lab. The culture is freeze-dried and then packaged in food-grade mylar. REUSABLE STARTER CULTURE - Your starter kit is taken from a mature and well-aged and freeze dried sourdough culture. From your starter batch, you can make new batches indefinitely. Feed daily and you have your dough starter for life! 100% VEGAN FRIENDLY - Along with your starter, sourdough is made with three simple ingredients, flour salt and water which makes for a delicious bread suitable for vegans. SLIGHTLY TART TASTE - Traced back to a rye flour kitchen not far from the Shipton flour mill in Tetbury, our Gloucestershire Rye Sourdough produces a slightly tart loaf, with a unique sourdough flavour. EASY TO MAINTAIN - Our starter is naturally very hardy and robust. Mix in some flour and water once in a while to keep it alive during periods when you're baking infrequently. To keep it near optimum health, feed it once a week or so and keep it refrigerated. Certifed Organic Rye Freeze Dried Sourdough Starter
