Getting into sourdough baking<\/a> can feel overwhelming. Back when I was a newbie, I didn\u2019t realize how much science and math was involved in my new hobby! Case in point: You may see other sourdough bakers throw out numbers like 1:1:1 or 1:4:4. These refer to feeding ratios, a simple but useful tool for maintaining your starter. If math makes you nervous, don\u2019t worry! Feeding ratios are easy to understand, and learning how to use them can help you customize your sourdough maintenance and baking schedule.\u00a0<\/p>\n

What is a sourdough feeding ratio?\u00a0\u00a0<\/h3>\n

In sourdough baking, a feeding ratio simply refers to the proportion of flour and water used to feed a sourdough starter.<\/span><\/p>\n

The feeding ratio comprises three numbers: first, the sourdough starter, commonly called the seed, followed by the flour and water. So, a 1:1:1 feeding ratio means the sourdough starter, flour, and water have been added in equal amounts by weight. For example, if you use 100 grams of seed, you will then add 100 grams of flour and 100 grams of water to feed your sourdough starter. A 1:2:2 ratio, meanwhile, means you would add 200 grams of both flour and water to 100 grams of sourdough starter.<\/p>\n

Different feeding ratios impact how quickly or slowly your sourdough starter peaks.<\/figcaption><\/figure>\n

Why are feeding ratios important?<\/span>\u00a0<\/h3>\n

Feeding ratios determine how much nourishment your starter receives. A starter needs sufficient nutrition to stay healthy. At a minimum, a starter should be fed at a 1:1:1 ratio, also known as a 100 percent hydration starter; this provides enough food to keep the community of microorganisms in your culture healthy, well-fed, and in balance, and it\u2019s a common feeding ratio (including in King Arthur\u2019s sourdough starter recipe<\/a>!).<\/p>\n

How much you feed your sourdough starter also determines how fast it rises. The more flour and water you add in proportion to the starter (in other words, the higher the last two numbers in the feeding ratio), the more time it will take for the starter to consume all its food. Therefore, the slower it will rise and the longer it will take to reach peak ripeness<\/a> (the point at which it is ready to be used to make bread).<\/p>\n

At warm room temperature (about 78\u00b0F) a healthy mature sourdough starter fed at 1:1:1 will usually reach its peak after about 4 to 6 hours. (This timeline can vary between 4 to 8 hours, depending on the health of your starter and the temperature of your kitchen.) This is when the starter is at its most vigorous and ready for baking. At this point, your starter has consumed most of the flour it has been fed; the starter will start to fall, decreasing in volume, and the natural yeast and good bacteria will become less active. After about 12 hours, it will be ready to feed again.<\/p>\n

How can I use feeding ratios in my sourdough baking routine?<\/span><\/h3>\n

A feeding ratio is just another variable you can manipulate to customize your starter schedule. Need your starter ready to bake with ASAP? Go for a smaller feeding ratio, so your starter peaks more quickly. Want to feed your starter in the morning so it\u2019s ready to use after work? Add a higher percentage of flour and water when you feed it, so that it grows more slowly.<\/p>\n

Here\u2019s a look at how this all works.<\/p>\n

Testing different sourdough feeding ratios<\/span><\/h3>\n

To explore how different feeding ratios allow you to tailor your starter to suit your schedule, I conducted an experiment comparing three common ratios.<\/p>\n

Let\u2019s say I\u2019m making a recipe that calls for 180 grams of starter.<\/span><\/p>\n

I tested three feeding ratios, 1:1:1, 1:2:2, and 1:4:4 to see how quickly my starter would be ready for baking. For this experiment, I used a Brod & Taylor Bread Proofer<\/a> to keep the starters at an optimal temperature (78\u00b0F).<\/p>\n

Note: It\u2019s important to remember that every starter is unique, and these timelines are merely a guide based on my personal starter. Depending on the health and maturity of your starter, as well as the temperature in your kitchen, your rise time may be shorter or longer.<\/em><\/p>\n
