Yes — guaranteed. Our starter is preserved at its biological peak, meaning the wild yeast and bacteria spring back to life the moment you add flour and water. As long as your water is warm (around 27°C) and your kitchen is at room temperature, you will see bubbling and rising activity within 2 hours. If for any reason it doesn't activate, we'll replace it free.

Building a starter from scratch takes 7–14 days of daily feeding before it's strong enough to bake with — and even then it can be unpredictable. Dough Dough is the world's first shelf-stable sourdough starter, ready to bake in 2 hours — preserved at peak biological activity, so you skip the entire setup phase and go straight to baking on day one.

Any unbleached flour works — bread flour, wholemeal, rye, spelt, or '00'. Do not use bleached flour as the chemicals can inhibit the culture. We recommend starting with a good quality bread flour for your first loaf.

Unopened, store in a cool dry place and use within 12 months. Once activated, your starter is a living culture you can keep indefinitely — just feed it regularly and it will last a lifetime.

Absolutely — this is designed with beginners in mind. The 2-hour activation removes the hardest part of sourdough. Once it's active, follow our revival instructions page and you'll have your first loaf ready the same day.

The culture is preserved using our proprietary process at its biological peak and arrives in protective packaging designed for postal delivery. It does not require refrigeration in transit and will remain fully viable until you're ready to activate it.
