When to Feed Sourdough: Daily, Weekly or Fridge?

Your sourdough feeding schedule determines whether your starter is ready when you need it. Use our starter maintenance calculator for exact amounts.

Room Temperature vs Refrigerated

Room temperature (20-26°C): Feed daily. Your starter stays active. A healthy starter doubles in 4-6 hours after feeding.

Refrigerated (4°C): Feed weekly. Before baking, give it 2-3 room-temp feeds to revive. See our starter ratio guide.

Daily Feeding Schedule

If you bake 2-3 times a week, keep starter at room temp. Feed once daily with 1:1:1. Discard half, then add equal flour and water. Our sourdough calculator has a Starter Maintenance tab.

Weekly Feeding (Fridge Storage)

Feed once a week. Discard half, feed 1:1:1, let sit 1-2 hours, then return to fridge. Revival feeds needed before baking.

Feeding Before Baking

1:1:1: feed 4-6 hours before mixing. 1:2:2: allow 6-8 hours. Use when doubled, domed, and bubbly. See our starter ratio guide.

Signs Your Starter Needs Feeding

Liquid on top (hooch): Starving. Feed immediately. • Flat, no bubbles: Past peak or hungry. • Doesn't double in 6 hours: Weak. Try 1:2:2. • Doubles in 3-4 hours: Very active. Perfect for baking.

Feeding Ratio and Schedule

1:1:1 peaks faster (4-6 hrs) than 1:2:2 (6-8 hrs). Use our starter calculator. Avoid these common mistakes.
