Why Won’t My Sourdough Starter Float?

Last Updated on November 23, 2021

Have you ever tried making sourdough starter but it never floats?
This happens to me every time!
I love baking bread and I always try to make my own sourdough starter.
I have been doing it for years now and I have learned a few things along the way.

Sourdough starters are alive organisms that feed off of sugars and acids found in flour. This process creates lactic acid bacteria LAB that give sourdough breads their distinctive flavor. LAB are not harmful to humans, but they can produce gas during fermentation. This gas builds up in the starter until it reaches a certain point where it cannot hold any more. At this point, the starter overflows and floats to the top of the liquid. This is normal behavior for a healthy starter. It is important to note that if the starter does not float after 24 hours, it is likely not ready to bake into bread.

What Effects How Well A Sourdough Starter Floats?

A good way to test whether your sourdough starter is ready to bake bread is to take a spoonful of the mixture and place it on a plate. If the mixture stays put, it is ready to bake bread. If it sinks to the bottom of the bowl, it needs more time.

Different Types Of Flour & Levels Of Gluten

There are different types of flour available in the market. These flours are used for making various kinds of baked products. Wheat flour is the main ingredient in baking. It is mostly used for making breads, pastries, cookies, cakes, pasta, noodles, pizza crust, pancakes, waffles, muffins, biscuits, croissants, bagels, crackers, pie crust, and many other bakery items. Other common ingredients used in baking are milk powder, sugar, eggs, butter, salt, yeast, leavening agents, and preservatives. Gluten is a protein found in wheat flour. It gives dough elasticity, strength, and helps in binding the gluten network together. Gluten is present in all forms of wheat flour. However, not all wheat flours contain gluten.

The Amount Of Gas That’s Held

When we talk about gas, we mean the amount of gas that is held within a given volume of air. This is measured in units called moles M. One mole of gas occupies 22.4 L at STP Standard Temperature and Pressure conditions. For every mole of gas that is released from a container, 1 mole of gas is absorbed into the surrounding atmosphere.

The Hydration Level

Hydration level is a measure of how much moisture is present in a substance. It is usually expressed as a percentage. A hydrated substance contains more water molecules than does an unhydrated substance. In other words, a hydrated substance contains more liquid than does an unhyrogenated substance. A substance is said to be completely hydrating if it contains 100% of its weight in water. Water is the only substance that is completely hydrating. Water is the only substance that can exist in two forms, solid and liquid. Solid water consists of ice crystals. Liquid water is composed of H2O molecules.

How To Know When Your Starter Is Ready To Use

When you start using your starter, you will notice that it starts to smell really good. This is because the yeast is working hard to break down the sugars into alcohol. Once the fermentation process is complete, the yeast will die off and leave behind a very strong alcoholic beverage. You will know when your starter is ready to use when you see the following signs: 1 The starter smells great!

There Should Be Some Foam On Top

If you see foam on top of your starter, it means that the yeast is active and working. It is important to note that if you see no foam on top of your starters, it does not mean that your starter is dead. The yeast is still alive but it is dormant. In order for the yeast to ferment properly, it needs oxygen. As long as there is air around the yeast, it will continue to work. Therefore, you should always check your starter every day to ensure that it is still alive. 2 The starter looks bubbly 3 The starter has a nice aroma

It Will Have Slightly Dipped/Fallen

1. Check the temperature of the water. If it is below 90 degrees Fahrenheit 32 degrees Celsius, it is probably too cold. This could kill off the yeast. 2. Make sure the water is clean. If it smells bad, it will affect the growth of the yeast.

It Should Have Risen Significantly

If the dough does not rise significantly after 2 hours, it is likely that the yeast was killed off during the proofing process. 3. Try adding 1 teaspoon of sugar to the dough. Sugar helps the yeast multiply. 4. Let the dough sit for another hour.


It should have risen significantly after 2 hours. 5. Add 1 teaspoon of sugar to dough. 6. Let the dough sit overnight.

What do you do if your sourdough starter doesn’t float?

Your dough probably needs more gluten protein. Gluten is what gives breads their structure. It’s formed when wheat proteins combine together during kneading. Adding more gluten will help your dough get stronger. Try adding 1/2 cup of whole wheat flour. This will give your dough more protein and strengthen it. How do I know if my dough is ready?

What does it mean if my sourdough starter doesn’t float?

If your starter isn’t bubbling, it could be because you’re using too much flour. Try adding only half the amount of flour you normally use. Or try adding a pinch of sugar to the mix. Sugar feeds the yeast and encourages it to reproduce quickly. Another possibility is that your starter is old. Sourdough starters lose their ability to bubble after about 2 weeks. To revive a stale starter, pour off any liquid from the bottom of the bowl and stir in enough new flour to make a thick paste. Cover the bowl tightly and let sit overnight. In the morning, stir in enough water to make a thin batter. Add the rest of the flour and continue stirring until the mixture forms a ball. Let the starter sit for another 24 hours, covered, and repeat the process again. After 3 days, you should have a lively starter that’s ready to use.

Why is my sourdough starter rising but not bubbling?

When making sourdough bread, you start with a mixture of flour and water. This mixture is called a "starter." It’s important to remember that the starter needs to ferment or develop for several days before baking. During this period, the yeast cells multiply and produce carbon dioxide gas. As the dough ferments, the gas pushes against the sides of the container, causing the starter to bubble and foam. This bubbling action helps aerate the dough and gives the bread a light texture. A good way to tell whether your starter is ready to bake is to see if it floats. If it doesn’t float, you’ll need to add more flour to get it to float.

How do you make dough float in water?

To remove mold from bread, place the bread in a bowl filled with warm water. Let soak for about 10 minutes. Then, lift the bread out of the water and gently squeeze out any remaining liquid. Rinse the bread under running water and pat dry with paper towels. If your sourdoug starter does not float, you need to add more flour. Mix 2 cups of flour with 1 cup of water until it forms a smooth paste. Add the paste back into your starter and wait for 24 hours. Repeat this process every day until your starter floats again.

Why is my sourdough starter so dense?

If your sourdough starter is thicker than 1/4 inch, you need to thin it down. To do this, mix equal parts flour and water together until it becomes a smooth paste. Add this mixture back into your starter and let sit for 24 hours. This will allow the yeast to break down the starches in the flour, making it thinner. How do I get rid of mold on bread?

What do I do if my sourdough starter is too thick?

To make dough float in water, you need to add a bit of salt to the water. Salt lowers the surface tension of water, allowing the dough to form a bubble.

What do I do if my leaven doesn’t float?

Sourdough starters are living organisms that produce acids during fermentation. These acids help to leaven breads and other baked goods. Sourdough starters are usually fed with flour and water. This process produces lactic acid bacteria LAB that break down carbohydrates into carbon dioxide and alcohol. As these LAB multiply, they consume sugars from the dough, producing more acid. This creates a self-feeding loop where the acids produced by the LAB feed the LAB. This process continues until the LAB die off and the dough becomes acidic enough to no longer support the LAB. At this point, the dough is ready to bake.

In conclusion, the big float is not the look you are going for.
