Sourdough Feeding Calculator: Master Your Starter for Perfect Sourdough

Sourdough baking is both an art and a science, and achieving the perfect loaf starts with a healthy and well-fed starter. To make feeding your starter simple and stress-free, we created the Sourdough Feeding Calculator. Whether you’re a beginner or an experienced baker, this tool takes the guesswork out of maintaining your starter and adapting it to your recipe needs. Here’s everything you need to know to get the most out of it!

Understanding Feeding Ratios

Feeding ratios are expressed in the format Starter:Flour:Water, representing the weight of each ingredient. They determine the balance of your feeding and have a direct impact on your starter’s health, activity level, and flavor.

Here are some common ratios and when to use them:

• 1:1:1: Equal parts starter, flour, and water. This is ideal for maintaining an active starter that peaks within 4-6 hours, depending on room temperature.

• 1:2:2: One part starter, two parts flour, and two parts water. This feeding stretches your starter further and slows down its fermentation slightly. Use this ratio if you’re refreshing your starter less frequently or need more starter for a recipe.

• 1:3:3: One part starter, three parts flour, and three parts water. This ratio is perfect for reducing sourness and for bakers who want a slower fermentation. 

• 1:10:10: One part starter, ten parts flour, and ten parts water. This ratio is useful when you want to greatly dilute the acidity of your starter. It’s often used for long-term maintenance in cooler environments.

• 1:15:15: One part starter, fifteen parts flour, and fifteen parts water. This ratio is excellent for slowing fermentation significantly, especially in warm environments or when maintaining a large amount of starter isn’t practical.

• 1:20:20: One part starter, twenty parts flour, and twenty parts water. This ratio is typically used for very mild starters or for bakers who need to significantly extend the time between feedings. It’s ideal for those in hot climates or when preparing a mild-flavored bread.

The right ratio depends on your baking schedule, room temperature, and the type of bread you’re making. If your kitchen is warm, opt for a higher ratio like 1:3:3 to slow down fermentation. Cooler kitchens or short timelines benefit from a 1:1:1 ratio.

How to Use the Sourdough Feeding Calculator

Our calculator is designed to make feeding your starter intuitive and precise. Follow these steps:

1. Choose Your Ratio: Select your desired feeding ratio from the dropdown menu. Unsure which one to pick? Check out our tips above to match the ratio to your needs.

2. Enter Your Starter Amount: Input the amount of starter you have (in grams). This tells the calculator how much flour and water to add based on your chosen ratio.

3. Optional – Input Your Recipe Starter Needs: If you’re baking and need a specific amount of starter for your recipe, enter it in the optional field. The calculator will show you how much flour and water to add to produce the required amount while keeping the ratio balanced.

4. Hit Calculate: The results will include:

   • Flour needed

   • Water needed

   • Total starter produced

   • Additional breakdown if you entered a recipe starter amount

5. Feed Your Starter: Combine the ingredients and mix thoroughly. Let it ferment at room temperature until it peaks, then store it according to your schedule.

What Is “Peak Time” and Why Does It Matter?

Peak time is when your starter is at its maximum activity level after feeding. It’s bubbly, doubled in size, and has a pleasant, tangy aroma. Using your starter at its peak ensures strong fermentation in your bread dough. The time to peak depends on:

• Feeding Ratio: Higher ratios (like 1:3:3) take longer to peak than lower ratios (like 1:1:1).

• Temperature: Warmer environments speed up fermentation, while cooler ones slow it down.

• Starter Health: A well-maintained starter will peak predictably, while a neglected one may take longer or behave inconsistently.

Monitor your starter after feeding to learn its pattern. You’ll soon know exactly how long it takes to peak under different conditions.

Troubleshooting Your Starter

If your starter isn’t performing as expected, here are some common issues and solutions:

• It’s Not Rising Well: Ensure you’re feeding it at regular intervals and using unbleached, high-quality flour. Adjust the feeding ratio to provide more food (e.g., 1:2:2).

• It’s Too Sour: Use a higher feeding ratio (1:3:3) to dilute the acids and reduce sourness.

• It Peaks Too Quickly: Lower the temperature or increase the feeding ratio to slow fermentation.
