You forget that in the UK beer is often sold in a naturally fermented state and does not contain vast amounts of artificially incorporated CO2 forced into solution under pressure.

A very common product has the keg fitted with a bung which must be removed before a tap is inserted into the orifice. fluorescein may be added between those procedures.
