Sourdough Starter Care Guide

Follow the guide included with your starter for rehydration, feeding, and ongoing care. Dehydrated starter usually shows meaningful activity within 48–72 hours. Your kitchen temperature, flour, and water can affect timing.

If your starter has not activated after 72 hours while you followed the instructions, see our activation guarantee. Contact us within seven days of delivery to choose a free replacement or a refund.
