Your starter has stopped bubbling, smells off, and you’re staring at a lifeless gray blob—panic mode engaged. **In the next few minutes you’ll learn the exact 8‑step rescue plan to revive sourdough starter** and get it bubbling again for your next loaf. No fancy equipment, no expensive kits—just fresh flour, warm water, and a few simple tricks.

## Why Starters Die (and How to Fix Them)

A starter goes flat when **temperature drops**, the flour gets stale, or you feed it too little (or too much). Bad bacteria thrive in cold, low‑food environments, turning the culture gray and sour‑cheesy. Identifying the cause lets you apply the right fix and prevents the problem from returning; for a structured approach, see our [5‑day plan to grow a strong sourdough starter](/sourdoughstories/the-5day-plan-to-grow-a-strong-sourdough-starter-for-perfect-crusty-bread).

## Step‑by‑Step Rescue Plan

### 1. Scrape Off the Crusty Top  
Remove the grayish film that forms on the surface. It’s dead yeast and possible mold—discard it, but keep the liquid underneath.

### 2. Measure a Tiny Amount  
Scoop **≈20 g (about one tablespoon)** of the remaining starter. A faint fermenty scent means there’s still life left.

### 3. Feed with Fresh, High‑Quality Flour  
Combine the 20 g starter with **100 g all‑purpose flour** and **100 g lukewarm water (78 °F/25 °C)**. This 1:5:5 ratio floods the culture with food.

### 4. 
Place the jar in a spot that stays **75‑80 °F (24‑27 °C)**—the top of the fridge, a turned‑off oven with the light on, or a warm countertop. Warmth is the secret sauce that jump‑starts yeast activity.

### 5. Wait 12‑24 Hours  
Leave the mixture untouched. Tiny bubbles along the jar walls signal that the yeast is waking up.

### 6. Repeat the Feeding  
If activity appears, discard half of the mixture (you’ll have ~100 g left) and feed again with **100 g flour** and **100 g water**. This “discard‑and‑feed” dilutes any lingering bad bacteria.

### 7. Check for Froth and Rise  
After the second feed, a frothy layer and a noticeable volume increase mean you’ve successfully **revived sourdough starter**. Give the jar a gentle shake—if it feels airy, you’re good to go.

### 8. Establish a Regular Schedule  
- **Room temperature:** feed once daily.  
- **Refrigerated:** feed once a week.  

Consistency is the real hero; a starter that gets regular meals rarely goes flat again, as outlined in our [5‑day plan to grow a strong sourdough starter](/sourdoughstories/the-5day-plan-to-grow-a-strong-sourdough-starter-for-perfect-crusty-bread).

## Quick Fix for a Smelly Starter

If the odor stays sour‑cheesy after two feeds, discard a larger portion (up to 80 %) and feed with a higher flour‑to‑water ratio (e.g., 1:6:6). Fresh flour and a warm environment usually neutralize the off‑smell.

## TL;DR – The Rescue Checklist

- Scrape off the gray crust.  
- Use **20 g starter + 100 g flour + 100 g water**.  
- Keep at **75‑80 °F** for 12‑24 h.  
- Discard half, feed again, repeat.  
- Maintain a **consistent feeding schedule**.

Follow these steps and your starter will be bubbling like a party in no time.
