Sourdough Starter Care Guide

Feeding schedules, fixes, and myths — all in one place.

Your Starter Is Alive — Here's How to Keep It Thriving

Sourdough Starter

Your sourdough starter is the beating heart of every great loaf you'll ever bake. It's not just flour and water — it's a living culture of wild yeast and bacteria that needs a little care, a bit of attention, and the right rhythm to stay strong and reliable.

If you treat it well, it will reward you with:

  • Dough that rises beautifully
  • Bread with better flavor, texture, and crust
  • A predictable, stress-free baking schedule

This guide will give you everything you need to feed, maintain, troubleshoot, and understand your starter — whether it's your first jar or your hundredth bake.

Feeding Schedules Made Simple

The most common and versatile feeding ratio is 1:5:5 — that's one part starter to five parts flour and five parts water (all by weight).

At around 70°F (21°C), that ratio typically peaks in about 9 hours — meaning your starter will double, dome, and be at its most active and ready to use.

Example schedule for a room-temp starter:

  • 7:00 a.m. – Feed your starter 1:5:5
  • 4:00 p.m. – Starter peaks (ready for baking)
  • 5:00 p.m.+ – Mix your dough

Pro tip: Warmer kitchens speed things up, cooler ones slow them down. If your starter peaks early or late, adjust feeding times or ratios — and don't be afraid to experiment.

Temperature Matters (More Than You Think)

Your starter's behavior is almost entirely controlled by temperature.

  • 74–78°F (23–26°C): Ideal — healthy fermentation and consistent peaks
  • 70–73°F (21–22°C): Slower, but stable
  • Below 68°F: Starter may become sluggish and need more time or warmth

A simple fix: keep your starter in the oven with the light on (oven off) for gentle, even warmth.

What to Do About Hooch

Hooch — the grayish liquid that sometimes forms on top — is just a sign your starter is hungry.

  • Stir it back in for a tangier loaf
  • Pour it off if you prefer a milder flavor

Either way, follow up with a feeding and adjust your schedule if it's happening often.

Busting Common Starter Myths

"I killed it — it smells weird."

Unlikely. Starters go through all kinds of smells as they mature. Keep feeding it and give it time.

"I need to feed it every 12 hours forever."

Only if it's at room temp all the time. If you're baking weekly, store it in the fridge and feed once a week.

"If I forget it overnight, it's ruined."

Not at all. Just feed it again — these cultures are far more resilient than you think.
