Overview

A 21.6-gram sachet of dehydrated sourdough starter that activates with added water and flour in about 12 hours, made for bakers who want a dormant culture that does not need daily feeding until it is time to use it.

This is the opposite format from a live jar culture: it sits shelf-stable with no refrigeration until activated, which suits anyone who does not bake often enough to keep feeding a live starter. Each sachet is sized as a single dose rather than an ongoing culture meant to be maintained indefinitely.

  • 21.6g dehydrated sachet, organic white wheat flour and wild yeast
  • No refrigeration needed until activated
  • Ready to use about 12 hours after adding water and flour
  • Includes step-by-step activation instructions

Who it's for

Works for occasional bakers who want a starter on hand without the upkeep of a live culture, and for anyone storing or shipping starter long-term. Less suited to bakers who want one culture they feed and reuse for years, since this format is closer to single-bake packets.

Pros and cons

Pros
  • No feeding or refrigeration needed before use
  • Activates in about 12 hours per the listing
  • One sachet covers a full loaf, a 12-inch pizza base, or a batch of pastry
Cons
  • Single sachet is closer to a one-bake dose than an ongoing culture

Performance notes

Activation is a straightforward rehydration: add water and flour and the listing states it is ready in around 12 hours, versus the days a fresh live starter typically needs to stabilize in a new kitchen. Being organic-certified with no commercial yeast added, the rise depends on the wild yeast surviving the drying process, which the sachet format is designed to protect against.
