F or more than 300 years, the stamp of the crown on top of a pub glass has stood as a guarantee that it is big enough to deliver a full pint. Ever since 1699, successive governments have found it necessary to measure and certify the pint and half-pint glasses made and used in this country.
The crown and number are official stamps and all licensed premises must use glasses bearing this stampm in order to adhere to weights and measures legislation. In a similar way, optics for spirits must have the measurment printed on them (25ml/35ml/50ml).
The Crown has been in use since 1699 as a guarantee of the size of pints and half pints. But now it is set to disappear, replaced by a European Union-wide "CE" mark instead. Campaigners say the change is another example of "excessive interference" by bureaucrats in Brussels.
As part of this effort to take back control, the Prime Minister pledged to “proudly” restore the Crown stamp on pint glasses. But the EU has denied having ever removed the right to feature the mark in the first place.
