Why Your Pizza Dough Smells Like Beer or Alcohol, and How to Fix/Prevent It [Causes & Solutions]
Dough that smells strongly of beer, yeast, or rubbing alcohol is a very common signal that your fermentation has gone way too long. This odor is caused by the yeast producing high levels of ethanol (alcohol) as byproduct. This page details the exact causes of the strong odor, helps you determine if the dough is still usable, and provides actionable solutions to prevent it in your next batch
This page is part of PizzaBlab’s Pizza Making Troubleshooting Guide. It provides a practical overview of the most common causes for this problem, each with a brief explanation, actionable solution, and links to related articles for deeper understanding.
The sections are listed from most to least likely, meaning the first cause typically represents the most common reason for this issue, with likelihood decreasing as you move down the list. That said, several causes can often overlap or share similar likelihoods – it’s ultimately up to your process to identify which factors are at play.
Cause 1: The Dough Is Severely Over-Fermented
Explanation:
Excessive alcohol production by the yeast has created a strong beer or alcohol-like smell.
Solution:
Avoid reaching over-fermentation (see: The Dough Ferments Too Quickly or Is Over-Fermented).

Additional Notes / Information
A dough that smells strongly of beer or alcohol indicates extreme over-fermentation – far beyond normal or desirable levels.
Dough in this state is better be discarded. While consuming it is not a health risk, its structure is very weak, leading to poor baking results.
The common advice to “smell the dough” as a way to detect over-fermentation is largely impractical. By the time the alcohol smell is strong and pungent enough to notice, the dough has already reached severe over-fermentation.
