Why Does My Bread Smell Yeasty?
Your bread can smell yeasty in either of these two cases; first, if you have added too much yeast or used the wrong type of yeast while preparing the bread, and second, if your bread is going through yeast contamination making it smell yeasty or chemical-ly. Yeasty smelling breads are also unpleasant in taste.
If you notice your bread tasting yeasty, that may be an indication the yeast is not activating properly. Your bread may smell yeasty due to either inadequate proofing or the addition of too much yeast.
Regardless of the alcohol level and the chemical reactions, you should not be serving yeasty bread that smells of alcohol. Yeast yeast is not the only reason why your bread will smell like alcohol. In short, when you catch the whiff of an alcohol or vinegary flavor in your bread, the culprit is probably the yeast.
Bread that smells of yeast typically indicates you are having problems with your digestive system. Bread that tastes like yeast typically means your body is producing too much acid.
Bread tastes bad because the yeast is eating sugar from the flour, producing alcohol. This type of smell occurs when the yeast settles into the bread, converting carbohydrates to carbon dioxide and alcohol. The smell comes especially from yeast fermenting, which is used in the bread.
Yeast is used to make both bread and alcohol, and it is a major reason why you may be noticing a smell. If you notice that there is a smell coming off of your bread that is VERY similar to the beer, liquor, wine, or vinegar your bread is made with, then you may realize the smell is coming from yeast being used in the process of making the bread. The good news is, typically, by baking your bread, you will be getting rid of both of that smell, as well as any alcohol within the mix that came out from fermenting the yeast.

| Yeast | Adding too much yeast to your bread can cause it to have sour yeasty taste |
Note that you can barely bake bread without using yeast, so there is no getting around that. While you can use yeast to make your own wine or another alcoholic drink, this does not mean that you are going to get the same effects when using it for baking bread. Some breads may even be made using beer instead of yeast (hmm, perhaps this is the key to that smell?).
To make home-baked bread, you usually need yeast, warm water, sugar, salt, butter, and bread flour (all-purpose works fine, too). If you want to bake great bread at home, you will want to incorporate yeast into the mix.

Your dough will not rise well, as much of the yeast will be encapsulated anyway, and it cannot get into the flour in your dough to feed. If you give the dough too long on the rise, it may end up being too light in the oven and will have that yeasty flavor.
We recommend patience, not just because such warm water kills the yeast, meaning that your dough does not rise, but because at least it may have an adverse effect on the texture and flavor of your finished bread, encouraging overproofing or excessive heat in the mixing process. Use cold rather than warm water when you are making your yeast for your bread mix, it may even have an effect. It is important to note if you are using powdered yeast rather than active dry yeast, you will have to dissolve it in hot water before mixing with your milk.
This water will draw in yeast, which makes your bread rise. Yeast needs moisture to thrive, but if you leave the dough too dry, the dough will not generate enough carbon dioxide gas to leaven the bread. If you are finding that your bread is fermenting excessively, this may be because the dough is too hot.
If your bread is going to go bad fast and be flaky, then you might have used too much yeast, your flour might not have the right protein content, or the amount of time you are leaving your dough to proof is either too long or too short. If your bread has a tart, yeasty flavor and a boozy smell, you may have used too much yeast. Or, you may have used stale yeast or mashed fresh yeast with sugar. If you have baked a pie and it tastes weird or has a tough texture, then you might have used too much sugar.

Too much sugar will cause the bread to have yeasty, acidic flavors, just because it produces too much yeast. It is also possible too much yeast will leave a bad taste after baking. In short, the yeasty taste in your bread could come from two things. There are two reasons why bread has yeasty flavors. There is the possibility of having too much yeast in the dough, or it is rising too quickly. Using very little yeast, combined with long fermentation, is all it takes to get rid of the yeasty flavors.
If your bread is over-fermented, it could be that your dough is too hot, or, if left overnight in the fridge, does not cool down fast enough to stop fermentation. You can notice this effect when kneading your dough, when the bread is baking, or even when the bread is ready to eat. Rising causes noticeable smells, as your bread does not properly cook.
It is important to note that the odor gets worse if you bake your bread often. You will find the smell of yeast in your home-baked bread to be similar to that which you smell when you open up a new packet of yeast, and that bread has a tart taste. All these flavor variations are caused by the fermentation process with yeast, and if the bread is made at home and uses beer as the rising agent, then this odor may be particularly intense.
Sometimes, there is the question whether a strange smell coming off a loaf could be a result of improperly stored bread. It is also clearer now why the bread might sometimes smell strange, and it does not necessarily mean that the loaf has gone bad. If the bread is left outside at room temperature, it is possible for that odor to actually intensify.
If you place a warming mat underneath your bowl of dough, or you place it in a gas oven with the pilot light on (as many people do), or use some other technique to create a warmer environment for your dough, there is a chance the rising temperature is simply too high…and if dough is rising at too high of a temperature, bread tastes yeasty. Adding too much water to the dough may result in the bread being super yeasty. About 1-2 percent of flour is needed for the overall yeast quantity. The dough may become flat because too much yeast, because too much yeast allows gases to escape in the expanding process. Occasionally, yeast contamination may appear on the bread after baking, causing it to have a chemical smell that is like acetone.
What does cause yeast to rise quickly?
Too much sugar will cause yeast to grow too quickly or in large quantities, and this (or simply too much yeast) will lead to a dough that has a nasty, yeasty flavor. Too much yeast can make a dough flat, by releasing gases before the flour is ready to expand.
How to get rid of yeast taste in bread?
If you’re noticing a yeasty flavor in your bread, there are a few things you can do to try to mitigate it. First, make sure you’re proofing the dough for the appropriate amount of time. Second, check the bread for doneness – if it’s under-baked, it will likely taste yeasty. Finally, try storing the bread in the fridge, which can help to reduce the yeastiness.
Does baking yeast smell bad?
If your yeast smells bad and you think it’s normal then actually, fresh yeast shouldn’t have a foul odor. It has a distinctive smell, but once it begins to smell bad, it is past its prime and should not be used. There isn’t much of a fragrance to dry yeast.
