Common questions

How long does buttermilk last in the fridge?

1–2 weeks from the date of purchase.

Can you freeze buttermilk, and for how long?

Yes. 3 months from the date of purchase.

How can I tell if buttermilk has gone bad?

Throw it out if it smells off, feels slimy or sticky, shows mold, or has changed color. Storage times assume it was handled safely and kept cold the whole time.
