There's no way nothing happened after 5 days.No. I opened the lid and it looked as it did when I put it in 5 days ago. In my opinion, and I know that isn't much, the yeast didn't do what it was supposed to. Whether it was dead in the package or my starter killed it, either way it didn't look or smell like anything happened
Either the yeast you pitched is still in her growing phase, she has started to ferment, or some wild yeast or bacteria will have taken over. I've left well-boiled wort in a closed pot for 2 days and it started to get foamy and developing a "musky" smell and flavor. It was fermenting!
