How long will a Busch Lt be good for once the can is opened,and it has been poured into a glass and left inside the fridge?
Busch Lite can last a maximum of six weeks if left inside a glass within the refrigerator. I wouldn't drink it if it is older than three weeks, but I like to be on the safe side.
It may be drinkable but it likely won't taste good due to absorbing odors from other items in the fridge and being flat. I'd just toss it.
That's gross, just drink it or toss it. It's carbonated, why would you want to wait, gross... It's only a cheap beer, really not worth drinking flat.
