I thought this would be pretty commonplace but can't find out much otherwise online...
Brewed a batch of around OG 1.6, used a relatively old smackpack of Wyeast 1762, made a starter, it still wasn't showing activity by the time I brewed... kept the wort in the pot (securely covered) for at least 36 hours, pitched the starter and everything smelled good for at least the first day. Now it has an unequivocally-staunchy smell. What to do? I'm guessing that it's not harmful to drink, but just stinky?
