Why Does My Sourdough Bread Smell Like Alcohol?
Most of the time, bread doughs do develop an alcohol-type smell due to too much yeast in them but your sourdough smelling like alcohol indicates the lack of feedings being given to the sourdough starters. This results in excessive acetic acid being produced, making the dough emit an alcohol-like smell.
Sometimes the bread will smell of alcohol, either when the dough is over-fermented and sugars are converted to alcohol, or from the residuals from that when the baking is done. When yeast ferments sugars, it produces carbon dioxide and alcohol (which is why bread dough often has a slight alcoholic smell). During the fermentation process, yeast cells break down the sugars to produce alcohol and carbon dioxide gas. The dough will rise up through the fermentation process, then the carbon dioxide gas will be produced within, creating small spaces you will see in the bread.

Sometimes carbon dioxide gas may have an odor similar to alcohol. The yeast in beer, which can smell like alcohol, uses the starch molecules and turns them into carbon dioxide and alcohol. Bread may smell like alcohol because of fermentation by yeast, the necessary component to make bread rise.
This smell is the alcohol produced by using yeast during the bread making process. When you get a wine-like smell, or a vinegar-like smell, from bread, that is likely because it is the yeast causing that. When your bread is baked, it will remove this aroma, as well as any alcohol from fermentation in the dough that came from yeast.
It is important to note that fermentation is a natural process, and that the smell of the alcohol goes away when you bake the bread. Your slices of bread smell winey due to yeast components, the dough prep, and bread preservation. When your slices of bread are done baking, they have an amazing, mouthwatering aroma. The regular process of making bread does not create a unique taste or smell.
Yeast is used to leaven the dough and provide bread with a distinctive taste. Yeast is the rising agent used in most loaves of bread (although it is possible to make successful yeast-free bread using another leavening agent, such as baking powder). Yeast is what gives sourdough bread that distinctive, tart flavor. Gas is what causes dough to rise, and the different alcohols and acids are what gives dough a distinctive taste that is like that of sourdough.
Anaerobic respiration leads to yeast fermentation, where the dough produces carbon dioxide, and, you guessed it, ethanol — the scientific name for pure alcohol. When proper fermentation occurs with too much yeast, you will soon have a dough that tastes too much like booze. Avoiding overly boozy tasting dough really comes down to finding the balance between the fermentation time and total yeast volume used in your recipe.

To counteract overly boozy-smelling dough, the easiest way is to use a lot less yeast, but still allow plenty of time for your pizza dough to rise and ferment. The more yeast you incorporate into your pizza dough recipe, the faster your dough ferments. The speed with which your dough over-ferments will vary depending on how much yeast is included in your dough, as well as how warm you keep your dough. If you let your dough ferment for more than 24 hours, it will eventually smell and taste like alcohol.
Your dough will not rise well, since much of the yeast will be encapsulated anyway, and it cannot get into the flour in your dough to feed. If you are making a dough with active dry yeast that you did not first dissolve, you will end up with dough full of tiny dry yeast pellets.
As the starter for the sourdough is left to grow without feeding, yeast in the flour is constantly fermenting to make ethanol, and as ethanol builds up, the starter for sourdough progressively tastes more like alcohol. A properly-fed sourdough starter will never smell too alcoholic, because the level of ethanol/alcohol is reduced each time we throw out and re-feed our sourdough starter with fresh flour and water.

The odor is caused by the yeast cells used to feed sourdough starters producing ethanol (alcohol) as a waste product. To solve the smell, just take your starter out of the fridge and leave it sitting at room temperature until the smell goes away.
If you are not feeding your dough frequently enough, a starter will begin to smell alcohol-like. If sourdough starter smells like vomit, then we need to keep our feed schedules higher in order to make sure the microbe cultures in sourdough starter are at their healthiest and most vigorous level when used to bake sourdough bread. The smell of alcohol in the sourdough starter is a signal that fermentation is occurring, however, when a sourdough starter smells overly boozy, this is usually a sign that we need to feed our sourdough starter more often.
If you are making sourdough bread and find the smell is excessively alcoholic, this is likely due to your starter. Any smell of alcohol that can build up within a starter is just from you not feeding it properly. The reason for the smell is that a starter starts eating its own waste, in addition to the yeast it has kicked out.
If the dough becomes over-fermented, it will give off a smell that is like that of old stale beer. Pizza dough that has a strong alcoholic odor typically means the dough has been over-fermented, and it is more likely to taste acidic. It is important to remember that bread dough with over-fermentation has an increased likelihood of having a strong, off-putting smell of alcohol. If the bread smells strongly like alcohol, then it can taste slightly bitter.
Because breads made with home-made yeast can smell strongly like alcohol or beer. Most of the time, the alcohol is baked off, but fermenting excessively with too much yeast creates a lasting alcohol smell. Too much fermentation, however, will take flavors too far, with a sour flavor coming through the extra alcohol and acids that are built up.
While you are leaving the bread to ferment, the fermentation process continues, and this is what is responsible for the flavor. You will either notice this strongly or not depending on how long you have kept your bread loaves after kneading the dough. If your loaf has a strange odor or strange color, chances are, it is expired. Sometimes, this smell returns when you place your bread in your pantry or outdoors, where it is at room temperature.
Why does my sourdough starter have so much hooch?
The liquid that builds up on your starter after a long period of no feeding is known as “hooch.” The alcohol produced by the fermentation of wild yeast is this liquid. Hooch is not a warning that your starting is in jeopardy; it does, however, show that your starting is starving and needs to be fed.
Why does my bread taste like alcohol?
There are a few possible reasons why your bread might taste like alcohol. It could be that the ingredients you used were contaminated with alcohol, or that the fermentation process wasn’t properly controlled. If you’re using a bread machine, it’s also possible that the machine itself is to blame. If your bread tastes like alcohol, the first thing you should do is check the ingredients you used.
Why does my bread smell like nail polish?
There are a few reasons why this might happen. If the bread is not kneaded long enough, the gluten will not develop properly and can cause the bread to produce an ammonia-like smell. This smell is caused by the breakdown of the proteins in the flour. Another reason why bread might smell like nail polish is if it is baked at too high of a temperature.
