The Festival will be operating a Challenge 21 rule which aims to cut down on underage drinking. If you look under 21, you will be asked to prove that you are over 18 in order to buy alcohol on site. The ‘Challenge 21’ initiative encourages sellers of alcohol to ask for official forms of identification from anyone that appears to be under 21-years-old. If a trader suspects someone is under that age and doesn’t have the relevant identification, e.g. passport, photo driving licence, citisencard, they will not be served. Stewards on site also have the power to request proof of age if they see anyone drinking alcohol who appears to be under age. The scheme is being promoted because it can be very difficult to identify accurately whether someone is 17, 18, 19 or 20 but is usually easier to determine whether someone is 21. However if young people have official identification to prove they are over the age of 18 they will of course be served legally.
