Bucks Fizz expiry date?

[ChoriChori]

I was given a bottle of Bucks Fizz last year in November from work. It’s M&S and I can’t find an expiry date anywhere on the bottle.

Will it be OK to drink? I can’t risk being ill, I’ve got a very important meeting on Mon and I’m also a carer for DH.

Taste it and if it is fizzy or blue tasting then chuck
Should be ok it's so sugary and has alcohol probably preserved
I reckon there is a sign on back saying how long or on neck check the neck?
One mo I have some in my fridge from this year I can check my one x

Buck's Fizz expires on the 12th of never :)

Bucks Fizz expired in 1986.
