Diagnosing a Failing Sourdough Starter
Hooch is an ethanol-water layer signalling underfeeding rather than spoilage, and sluggishness usually traces to low temperature, over-dilution, or chlorinated water. Fuzzy or pigmented colonies, pink or orange slime, and any distinctly putrid odor indicate contamination and mean discarding the culture, since mycelium penetrates far beyond the visible spot.
