A man in England made a surprising discovery recently when he opened his mother's cupboard to find an unopened bottle of Guinness.
What made it even more fascinating was that the half-pint bottle of stout is sealed with a cork and has been sitting there untouched for over 50 years.
Tim believes it dates back to the 1960s and was brought over by his grandfather, who emigrated from Monaghan to the UK - but he has no idea why the Guinness was never drank.

Taking to Twitter to share his unusual find, Tim wrote: "Talk about best before dates! Found a half-pint bottle of Guinness with a cork top in my mum's cupboard. Fifty years old?"
People were fascinated with the old Guinness bottle as one man pointed out that the 'S.E.' markings on the front of the bottle were a "relic" of Irish history.
The Twitter user replied: "The S E branding is proper history in its own right. Saorstát Éireann/[Irish] Free State so bottle alone is from earliest the twenties. Great find."
Tim replied: "It came from my grandad apparently. He moved to England from Monaghan in 1946. Can't imagine it's that old though."
He later pinned down the decade he believes the bottle was from, writing: "1960s we think. Just don't know why my grandad brought it back from Ireland but didn't drink it!"
Many people pointed out how rare it was to see a Guinness bottle sealed with a cork as that practice stopped over 50 years ago.
In 1969, Guinness stopped sealing bottles using corks and replaced them with metal caps instead - which we still use today.
One person wrote: "Congratulations to taking what seems to be the only photo on the web of a bottle of Guinness sealed with a cork."
