Starter Care: keeping your sourdough starter alive and active
A healthy sourdough starter roughly doubles in size within 4 to 8 hours of feeding at a 1:1:1 ratio at room temperature — if yours takes much longer than 8 hours, that's the clearest early sign something needs adjusting. This hub covers feeding schedules, reviving a starter neglected for weeks, drying starter for storage or gifting, and keeping one alive during a 2-week vacation. The starter troubleshooter diagnoses a sluggish or inactive starter step by step.

Frequently asked questions
How often do I really need to feed my starter?
Once daily at room temperature, or once weekly if refrigerated, is the standard baseline — refrigeration slows fermentation enough that weekly feeding keeps a starter alive without daily attention. Very active starters in warm kitchens sometimes need feeding twice a day to avoid over-fermenting between feeds.
Can I revive a starter that's been neglected for weeks or months?
In most cases yes — even a starter with a layer of dark liquid ('hooch') or slight discoloration on top can usually be revived with 2 to 4 consecutive daily feedings, discarding most of it each time. A starter is only truly dead if it shows pink, orange, or fuzzy mold growth, which means starting over.
What's the best way to keep a starter alive while on vacation?
For trips under 2 weeks, refrigerating a well-fed starter is usually enough without any feeding needed. For longer trips, drying a portion of starter into flakes (which can store for a year or more at room temperature) and rehydrating on return is the more reliable option.
How do I dry my starter for long-term storage or gifting?
Spread a thin layer of active starter on parchment paper and let it air-dry at room temperature for 24 to 48 hours until brittle, then break it into flakes and store in a sealed container. Rehydrating takes about 3 to 5 days of regular feeding to return to full activity.
Why does my starter smell different from day to day?
A shift from tangy-yogurt to more acetone-like or vinegar smells usually just reflects where it is in its feeding cycle — closer to hungry produces sharper smells, closer to freshly fed produces milder ones. A genuinely unpleasant, rotten smell (not tangy or sharp) is one of the few signs something has actually gone wrong.
Rye or wheat flour — which is better for a starter?
Rye flour ferments faster and produces a more active starter due to higher natural enzyme and mineral content, which is why many recipes recommend starting a new culture in rye even if you'll maintain it in wheat afterward. An established wheat starter works fine long-term once past the initial, most fragile week.
