Heirloom starter questions, answered

What actually makes a sourdough starter "heirloom"?

Time and continuity. A heirloom starter is a culture that has been maintained and baked with for years, so its microbial community is stable, vigorous, and predictable. You skip the fragile infancy — you start with a grown-up culture that already knows the drill.

Will an heirloom starter keep its character in my Australian kitchen?

It will become yours, and that's the charm. Your local flour, water, and air gradually shape the culture over time. The lineage and resilience stay — the flavour settles into something distinctly your own kitchen.

How long will it last once I've activated it?

Decades, if you feed it. A well-kept starter is essentially immortal — bakers hand jars down to their kids. You can even split yours and gift portions to friends, which is exactly how heirloom cultures travel the world.
