Daily Sourdough Starter Feeding Routine

Why Routine Matters

Regular feeding creates consistency in:

• Fermentation timing: Your starter peaks at predictable times
• Flavor development: Consistent sourness and complexity
• Yeast activity: Reliable rising power for baking
• Bacterial balance: Stable, healthy microbiome

The Basic Daily Feed

A standard feeding routine for room temperature storage:

What You Need

• Your active starter
• Fresh flour
• Room temperature water
• Clean jar (or your regular jar)
• Kitchen scale
• Spoon or spatula

Standard 1:1:1 Feeding

1. Measure starter: Keep 50g of your existing starter
2. Discard the rest: Remove excess (use for discard recipes)
3. Add flour: Add 50g fresh flour
4. Add water: Add 50g room temperature water
5. Mix thoroughly: Stir until no dry flour remains
6. Mark the level: Place rubber band at current level
7. Cover loosely: Return to warm spot

Choosing Your Feeding Time

The best time is whenever you can be consistent:

Morning Feeders

• Feed before work/starting your day (6-8 AM)
• Starter peaks mid-afternoon to evening
• Perfect for afternoon or evening bakes
• Discard makes great breakfast pancakes

Evening Feeders

• Feed after dinner (7-9 PM)
• Starter peaks overnight or early morning
• Perfect for morning bread making
• Fits well with office schedules

Twice Daily (Active Bakers)

• Feed morning and evening (12-hour intervals)
• Maintains maximum activity
• Necessary in very warm conditions
• Best for frequent bakers

Understanding the Feeding Cycle

After feeding, your starter goes through predictable phases:

Phase 1: Lag (0-2 hours)

Little visible activity. Microorganisms are adjusting to fresh food supply.

Phase 2: Rise (2-6 hours)

Active bubbling begins. Starter expands as yeast produces CO2. This is when activity accelerates.

Phase 3: Peak (4-8 hours)

Maximum volume reached. Domed top, lots of bubbles, passes float test. Ideal for baking.

Phase 4: Fall (8-12+ hours)

Starter deflates as food depletes. Top flattens, then may sink. Hooch may form.

Adjusting Ratios for Your Schedule

Change feeding ratios to control timing:

For Slower Fermentation

Use higher ratios (more flour and water relative to starter):

• 1:2:2 - Peaks in 6-10 hours
• 1:5:5 - Peaks in 10-14 hours
• 1:10:10 - Peaks in 14-18 hours

Example 1:5:5: 10g starter + 50g flour + 50g water

For Faster Fermentation

Use lower ratios (more starter relative to flour):

• 2:1:1 - Peaks in 2-4 hours
• 1:1:1 - Peaks in 4-6 hours (standard)

Temperature Effects

Temperature dramatically affects timing:

Signs of a Well-Fed Starter

• Doubles (or more) in volume after feeding
• Predictable rise and fall pattern
• Pleasant sour or yeasty smell
• Lots of bubbles throughout
• Passes float test at peak
• Returns to similar volume after falling

Common Routine Questions

What if I miss a feeding?

One missed feeding rarely causes problems. Your starter will be hungry and may have hooch on top. Stir it in and feed as usual. Activity should return to normal within 1-2 feeds.

Can I change my feeding time?

Yes, gradually shift by 1-2 hours per day until you reach your new target time. Sudden large shifts may temporarily affect activity.

How much discard do I need to save?

Technically just a few grams will work, but most bakers keep 25-50g for convenience and to have enough for the float test.

Do I need to feed every day?

Only if stored at room temperature. Refrigerated starters can go 1-2 weeks between feedings.

Weekly Routine Suggestions

For Daily Bakers

Daily feeding at consistent time, using peak starter for each bake.

For Weekend Bakers

• Monday-Thursday: Starter in fridge
• Friday: Remove from fridge, feed in evening
• Saturday: Morning feed, afternoon/evening bake
• Sunday: Feed and return to fridge

For Occasional Bakers

• Keep starter in fridge
• Feed once weekly for maintenance
• 2-3 days before baking: begin daily feeding to reactivate
