THE Alchemist Oxford cocktail bar and restaurant is offering a free 'colour-changing' cocktail in exchange for donations to Oxford Food Bank all day today.

Branches of the cocktail and food chain are hosting swap shops as part of a drive to tackle food poverty in local areas.

People are encouraged to being in tinned, dried or packaged food to the Westgate branch of The Alchemist, with items then being sent to Oxford Food Bank in Botley.

A member of staff at The Alchemist Oxford said that 'anything non-perishable, in-date and unopened' is welcome at the swap shop, and called for as many donations as possible.

However they added: "We can only give one free cocktail per person, but the more food you bring the better it is for the cause."

The Grey Goose vodka-based cocktail tastes like apples and changes colour from pink to purple. A non-alcoholic 'mocktail' version is also available.

The company is already partnered with national poverty charity Foodinate, and when certain items are ordered from the menu the restaurant will donate food to those in need.

Oxford Food Bank accepts food donations from anyone and collects fresh food from supermarkets. This food is then distributed to local charities which provide food to those in need.
