Puede que tu levadura esté vieja.
Meaning
The speaker is expressing a possibility that the listener's yeast is no longer fresh. It suggests doubt rather than certainty, often used when a recipe isn’t rising as expected.
When to use
Use this phrase in a kitchen or baking conversation when you suspect the yeast might have lost its potency, or more generally when you want to point out a possible problem with something that should be fresh.

Cultural Tip
In many Spanish‑speaking households, fresh yeast (levadura fresca) is preferred for breads and pastries. When using dry yeast, check the expiration date; an old pack can cause dough not to rise, leading to phrases like this. Also, note that 'levadura' can refer to both fresh and dry yeast, so context matters.
