Shipping & Storage

Your dehydrated sourdough starter ships dry and dormant so it can travel safely and reliably. When it arrives, you’llactivate it at home using flour + water to turn it into an active, living starter.

How We Ship Your Starter 

  • Shipped via USPS 
  • Starter arrives dehydrated (dry) for stability in transit 
  • Includes activation instructions so you can start confidently 

Because it ships dehydrated, it’s typically more travel-friendly than a liquid/active starter under normal shipping conditions. 

Food-Safe Handling (Simple Rules) 

Sourdough starter is a living culture. Handle it like any food prep: 

  • Use a clean jar and clean utensils 
  • Wash hands before handling 
  • Keep the jar covered (but not airtight if your activation instructions say it needs airflow) 
  • Avoid cross-contamination from raw foods and dirty tools 

How to Store Your Starter (Dehydrated/Before Activation) 

If you’re not ready to activate right away: 

  • Keep the packet sealed 
  • Store in a cool, dry place (a pantry is fine) 
  • Avoid heat, humidity, and direct sunlight 

Humid climate tip: Keep the sealed packet inside an airtight container in a cool cabinet.

Hot or Cold Weather Delivery Tips 

Because your starter ships dehydrated, it’s naturally more resilient in transit than a liquid starter. Still, we recommend: 

  • Don’t leave deliveries in a hot mailbox or direct sun for extended periods 
  • Bring it inside promptly when it arrives 

If you suspect extreme heat/cold exposure affected your starter, email support@sourdoughstarter.com and we’ll help.
