Sourdough starters produce hooch when they are hungry. (After the bacteria and yeast have consumed all available sugars and starch, the yeast get stressed and start to produce alcohol.) The same way that you might feel more or less hungry on different days, we suspect that sourdough metabolism may change over time – making it more or less likely to produce hooch.

**You should always feed your starter at least once a day (i.e., every 24 hours). After a few days, when you notice that the starter is consistently falling from its peak rise (i.e., high tide mark) and producing hooch after 24 hours, you should start feeding your starter twice a day. Feeding more often may provide enough nutrients that your starter stops producing hooch.
