Observing these changes, like the appearance of bubbles and the growth in volume, is a very exciting part of the process, honestly. It's a clear sign that your starter is, actually, coming to life.

When is Your Starter Active?

The main indicator of an active starter is its behavior after feeding. It should become noticeably bubbly and, in fact, double in size within six to eight hours of being fed.

Checking for those bubbles and the rise is, you know, a good daily habit to get into.

If it does, a few extra feedings can often help it get back on track. Fresh sourdough starter is, really, a wonderful resource, and knowing when it's ready makes all the difference for your baking projects.

The basic idea is to remove some of the old starter and replace it with fresh flour and water, which, you know, provides new food for the yeasts and bacteria. This continuous cycle is what sustains your starter indefinitely.

Consistency in feeding is pretty important, especially in the early stages. While some people maintain their starters on the counter with daily feedings, others keep theirs in the fridge and feed them less often. The King Arthur Baking School’s virtual sourdough basics class, as a matter of fact, guides you through these maintenance routines. It's all about finding a rhythm that works for you and your baking schedule, honestly.
