Google says all opened milk lasts 4-7 days. It also says all unopened milk lasts 5-7 days. But my bottle has a BEST BY date of JUNE 10/22 , that is 5 months. Both can't be right, Either the article is wrong or the date on my bottle is a mistake of some kind. It's Nestles brand milk. Does someone have a clue.?

As you can tell I don't usually buy milk.

Was the milk stored at ambient temperature in the place you bought it? If so, you’ve probably bought ultra heat treated (UHT) milk. This kind of milk has been through a more aggressive sterilisation process than regular milk (which is pasteurised). UHT milk lasts much longer unopened because the bacteria that make milk curdle have been killed, but has a different taste (which most people find less pleasant than fresh milk).

    @ Rdd ...I never would have guessed. Thank you That would explain it. I bought it online and used curbside but if I can find powdered Carnation skim milk that may last longer even opened. I use it to make corn bread and don't drink it.

    Glad to help! UHT and powdered milk are good to cook with. UHT milk lasts longer than fresh milk even when opened, so it’s a good choice for irregular use.
