This is the question I get more than any other. It shows up in the feed almost every week, usually with a photo of a jar and a sentence that starts with "I've been feeding it for two weeks and..." So I made a video about it. Here's what I'll say up front: a starter that isn't doubling is not automatically a dead starter. Most of the time it's alive and doing exactly what the conditions are telling it to do. The problem is almost never the flour or the water. It's usually something quieter than that. Watch it, then come back and tell me which one you recognized in your own jar. https://youtu.be/nTxWfRwevd4 If your starter has been stubborn, post a photo in the comments. Tell me your feeding ratio, your flour, and roughly how warm your kitchen sits. That's usually all I need to spot it. Perfection is not required. Progress is.
