When the Starter reaches a consistent activity level, it’s called a Culture. With proper care are routine feedings, your Sourdough Starter can be sustained indefinitely.
To sustain the Starter, a baker uses a 3-step system.
A. Divide It ...
A1 Reserve ⅓ of the Starter...
Before any dough mixing is begun on a given production day, a small portion of the fermented Starter is removed from its original container. It’s put aside in a safe place. This can be a separate area of the bakeshop or sometimes back in the refrigerator, if the ambient temperature of the bakeshop is higher than 75°F.
