Sourdough Starter Ratios - Amy Bakes Bread? ›

So, a sourdough feeding ratio is the relative amount (referring to weight) of old sourdough compared to fresh flour and water. Typical feeding ratios are 1:2:2 or 1:3:3 (old sourdough: fresh flour: water). However, even extreme ratios like 1:50:50 would still work.

There is no single best ratio, but I've found a ratio of 1:5:5 fed twice daily at 12-hour intervals to produce a sourdough starter that's strong and healthy. This ratio corresponds to 20% ripe starter carryover, 100% water, and 100% flour (a mix of whole grain rye and white flour) at each feeding.

It's usually given as starter:water:flour, so a 1:1:1 ratio means 1 part starter, 1 part water, and 1 part flour. 1:2:2 means 1 part starter, 2 parts water, and 2 parts flour, and so on.

What Happens If You Feed a Sourdough Starter Too Much Flour? If you add more flour than water into your sourdough starter jar, it will be a very stiff starter. This is not always a bad thing, and sometimes extra flour is necessary to rectify a runny starter or make the starter peak at a later time.

With each sourdough starter feeding, you'll be discarding some to avoid it from becoming overly acidic. Most will compost or trash this discard, but you can save it and use it in other recipes!

To keep a smaller starter, you will save just 20 grams (about 1 heaping tablespoon) of active starter, feeding it with 20 grams of water and 20 grams of flour. This will yield 60 grams of starter which is just enough to maintain.

When we send out our dried sourdough starter packets, the instructions say to make it like a thick pancake batter. That is the viscosity we prefer. We recommend doing this with a 100% hydration - remember, that is 50% flour and 50% water.

If you do not have whole wheat flour, just use all purpose flour instead. The starter will be fine. I switch to all purpose flour for the feedings because it's reliable, inexpensive and practical for everyday baking (remember, a portion of your starter is removed, discarded, or used for something else).

Should sourdough starter be feed by weight or volume? ›

If you're feeding a sourdough starter by weight, the ratio of starter to water to flour is 1:1:1. So If you're using 50 grams of starter, add 50 grams of water and 50 grams of flour. If you want to feed a sourdough starter by volume, the ratio of starter to flower to water is 1:1:1.75.

A 1:2:2 feeding ratio would consist of one part existing starter, two parts flour and two parts water. For example, if you have 30g of existing starter, you would feed it 60g of flour and 60g of flour. The most common feeding ratios for daily maintenance are 1:1:1 or 1:2:2.

Since ratios compare data between two numbers of the same kind, this means your formula would be A divided by B. For instance, if A equals 5 and B equals 10, then your ratio will be 5 divided by 10. Now, you're ready to solve the equation. Divide A by B to find a ratio. In this case, the answer is 0.5.

Once your starter is established, you can transition to feeding it 100% bread flour or all-purpose flour. An established starter (e.g., 14-30 days after creation) has a robust microbial population, and the feedings from that point forward are primarily providing the food, not additional microbes.

How much sourdough starter equals a packet of yeast? As a general rule, 100g of sourdough starter can be used to replace one packet of yeast (a packet usually contains 5-7g of commercial yeast).

% levain to flour ratio. Typically 10% to 30%, depending on how long you want the dough to ferment.

Feed a sourdough starter 4-12 hours before starting the dough, ensuring it is active and bubbly. Add warm water, active starter, salt, and flour to a large mixing bowl. A kitchen scale will give the most accurate results. Mix together with wooden spoon or even just your hands.
