How long does buttermilk stay fresh?

Answer 1

Look at the due date.

Check for an expiration date, and if there is not one just smell it. It will have a foul smell if it's bad. If there is an expiration date, most products are good a week after that date, so just add a week to that date.

Answer 2

I've read that milk or buttermilk lasts five days beyond the date on the carton.

Answer 3

This food will only last a few days. 3 days in the refrigerator if the milk is stored properly. Place in an air tight container for the best results.

Answer 4

1-3 hours
