M: Is the general rule that dead yeast sinks
G: Yes, in general, dead yeast tends to sink, while live yeast remains suspended or floats. This is because live yeast cells produce carbon dioxide, which can help keep them buoyant. Once yeast cells die, they lose their ability to generate gas and often become denser, causing them to settle at the bottom. However, factors like temperature, fermentation conditions, and yeast strain can affect this behavior.
