Why Your Pizza Crust Has a Strong Yeasty/Musty Flavor or Smell (Causes & Solutions)
A noticeable yeasty or musty aroma in the finished pizza crust is a clear sign of using too much yeast relative to your fermentation time and temperature. This page breaks down the exact causes and provides actionable solutions to eliminate these undesirable off-flavors and achieve a clean, pizzeria-tasting crust
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: Too Much Yeast in the Dough
Explanation:
Using too much yeast can lead to off-flavors, including musty or yeasty aromas or flavors (see additional notes below).
Solution:
Ensure the yeast amount aligns with the intended fermentation time and temperature, and avoid using more yeast than necessary. Use PizzaBlab’s dough calculator to determine the correct yeast amount for your fermentation conditions.

Additional Notes / Information
A properly fermented dough, whether short or long fermented, should not taste or smell of yeast. Any noticeable yeasty aroma or flavor is a clear sign that too much yeast was used.
In long-fermented dough, flavor comes from the byproducts of yeast activity, not from the yeast itself. Using excess yeast introduces the flavor and aroma of the yeast rather than the desirable fermentation byproducts, leading to musty, yeasty off-flavors.
Many online recipes use excessively high yeast levels to make the dough “fool-proof,” ensuring it rises under almost any conditions – this comes at the cost of flavor and dough quality, often resulting in these undesirable yeasty notes.
