40 to 60 years old is not even in the ballpark. How do these links even suggest that?
Swan Gold is a mid-strength lager, with a small head and a quiet bitter aroma (3.5% alc/vol). Production commenced in 1978.
The very oldest bottle ever produced would be 39 years old, but it was still being produced and popular 20 years ago IMO.
Wacky. CV promotes the beer bottle & you continue it. Do try to not tell us IC who is the same.. Lmfao FFS.
