How to Capture Wild Sourdough Yeast at Home 🍞

No yeast packets. No store runs. Just flour, water, and a little patience.

🫙 What You'll Need

- Whole wheat or rye flour (to start)
- All-purpose or bread flour (for later feedings)
- Non-chlorinated water
- A clean glass jar

📅 Day 1
Mix:

- 60g whole wheat or rye flour
- 60g lukewarm water

Stir until smooth. Cover loosely with a lid or cloth and place in a warm spot (70–78°F / 21–26°C).

📅 Days 2–3
You may notice a few bubbles and a slightly funky smell. That's completely normal.

Each day:

1. Discard about half the starter.
2. Feed the remainder with:
- 60g flour
- 60g water

📅 Days 4–6
The aroma should become pleasantly tangy, similar to sour beer or yogurt. Your starter should begin rising and falling between feedings.

Switch to all-purpose or bread flour. If your kitchen is warm, feed twice daily.

📅 Day 7+
Your starter is ready when it:
✅️ Doubles in size within 4–8 hours after feeding
✅️ Is packed with bubbles
✅️ Smells fresh, tangy, and slightly ye**ty

Float Test: Drop a spoonful into water. If it floats, it's active and ready for baking.

❄️ Cold Kitchen?
Some starters need 10–14 days. Keep feeding consistently and be patient.

The Day 3 Stall
If your starter suddenly stops bubbling after an early burst of activity, don't throw it away.

That's a normal phase where beneficial bacteria are taking over. Keep feeding on schedule, and it will come back stronger.

Sourdough is just one of dozens of traditional food-preservation and survival foods that helped generations thrive long before supermarkets existed.
