Bottom Line. Milk generally stays fresh for up to five days after the date on the carton, but itâs better to be safe than sorry. Note the date on the milk before you buy it, purchase the carton stamped with the latest date available and then use the date as a guideline, not a rule. Your nose is likely the best judge.
Generally milk will still be good for a week to 10 days after the expiration date, so your butter milk is probably O.K. I know what you mean though about the taste of Butter Milk, However if it is sour, (spoiled,) you should be able to tell by the taste and the smell.I would suggest that if you're in doubt, just go buy another quart. It's better to be safe than sorry when it comes to ingredients.Just my 2 cent's worth.y brother and I used to drink so much buttermilk when we were little!! Nice and cold..so refreshing! The way you can tell if it's bad or not is simple. When it's bad, it will be clumpy, with water floating on top. It won't just be pleasantly sour.
