How do I know if I killed my sourdough starter?

You know you've killed your sourdough starter if you see fuzzy, colored mold (pink, orange, green, blue), a foul, rotten smell (beyond sharp vinegar/acetone), or if it remains completely inactive (no bubbles, no rise) even after several feedings with fresh flour and water, especially after a long neglect, but always discard if you see mold.

Signs of an overfed sourdough starter include lack of bubbles and rise, a runny or watery consistency, a mild, floury, or slightly sweet smell instead of tangy, and producing dense, flat bread.

When should I throw away sourdough starter?

You discard sourdough starter to manage its size and acidity, primarily when it's young and establishing (days 5-7+) or when you need less starter for feeding, but if it's mature and on the counter, discard before each feed; discard immediately if you see mold or pink/orange streaks, but otherwise, save the "discard" (fallen starter) for other recipes like pancakes or muffins. 

Is it possible to overfeed a sourdough starter?

Yes, you can overfeed a sourdough starter, which dilutes the yeast and bacteria, making it weak, sluggish, and less bubbly, but it's usually not fatal and can be fixed by feeding it less or using a higher ratio of flour/water to starter. Signs of overfeeding include runny consistency, lack of rise, and an unpleasant, overly sour smell, but a properly revived starter will regain strength with correct feeding, typically waiting for it to peak before the next feed. 

How long is too long for starter to sit out?

It depends. If you plan on making in the next couple of days, you can just return to the fridge what's left in the jar, without feeding it. However, if you plan it to leave it unfed for longer (a week or longer), I would advise to feed it.

What does an overfed starter look like?

An overfed sourdough starter looks watery and thin, lacks strong bubbling activity, and might develop a strong alcoholic or vinegary smell (hooch) because the yeast and bacteria have consumed all their food and become overwhelmed.

The 1:1:1 method for sourdough starter is a feeding ratio using equal parts by weight of mature starter, water, and flour (e.g., 30g starter, 30g water, 30g flour), which makes it rise quickly and is good for maintenance, though higher ratios (like 1:2:2 or 1:4:4) are often used for slower fermentation or larger batches. It's a basic, balanced feeding that keeps the culture healthy and active, with the first number always representing the "seed" starter you're keeping.
