Why is my sourdough starter not rising anymore?

The most common reasons are a cold kitchen, feeding too infrequently, or a brand-new starter that simply needs more time. A starter slows dramatically below 20 °C and nearly stops below 15 °C. Move it somewhere warmer, feed it on a steady 1:1:1 schedule, and most quiet starters come back within a day or two.

How do I know if my sourdough starter is dead or just hungry?

A starter is almost never truly dead. Hungry starters look flat, smell sharply sour, and may show hooch on top, but they revive with regular feeding. The only real death sentence is fuzzy mold or a pink or orange streak, which means you throw it out and start over. Everything else is a tuning problem, not a funeral.

Why is my sourdough starter runny or watery?

A soupy starter usually means it is overhydrated, too warm, or overdue for a feed. The enzyme amylase keeps breaking down starch into liquid the longer it sits. Feed it with a touch more flour than water to firm it up, keep it cooler, and feed more often. It should return to a thick, pancake-batter texture.

Can I fix a sourdough starter that stopped rising on day 3?

Day 3 doesn't usually need fixing at all. The big rise on day 2 is a false rise from other bacteria, and it collapses as the real wild yeast takes over. The flat, funky lull that follows is the most misread stage in starting a starter. Keep feeding on schedule and it almost always roars back by day 5 or 6.

How do I revive a neglected sourdough starter from the fridge?

Take it out, pour off any hooch, and discard down to a tablespoon. Feed it 1:5:5 with warm flour and water, keep it at 25 to 28 °C, and feed again every 12 hours. A starter neglected for weeks often looks hopeless but revives within two to three feeds. Patience beats panic.
