The "revolutionary new product" mentioned by HP Bulmer in its February financial report is rumoured to be a schnapps-based drink, to be launched in six months time.

The drink, which is being developed under the working title 'Storm', is said to contain a device that squirts a range of coloured flavourings into the bottle once a screw-top is opened.

Bulmer's previous attempt to enter the alcopop market via Strongbow Spice has been unsuccessful.
