What is a common cause of poor bread rise?

• A. Using too much salt
• B. Using inactive or expired yeast
• C. Baking at too high a temperature
• D. Not enough kneading

Answer: (B)

Using inactive or expired yeast is a common cause of poor bread rise because yeast is essential for fermentation, which produces gas that causes the bread to rise. Yeast must be alive and active to perform its function effectively; if the yeast is expired or inactive, it won't produce the necessary carbon dioxide when it ferments the sugars in the dough. This lack of gas production results in a dense loaf with little to no volume. In contrast, using too much salt can inhibit yeast activity, but it often does not completely prevent rise. Baking at too high a temperature can lead to rapid crust formation, which may inhibit further rising but does not directly impact the yeast's effectiveness before baking. Not enough kneading can affect gluten development and the overall texture of the bread, but if the yeast is active, it can still rise; the gluten structure may just be weak. Thus, the key issue of inactive or expired yeast directly prevents proper fermentation and rise, making it the most critical factor related to this question.
