Why is it that some pubs won't serve 'snakebite'? (3/4 cider, topped up with lager and blackcurrant) Does it cause a dangerous chemical reaction or something?

Cath Wilkins, London, UK

• Having worked behind a bar for many years, I know nothing of chemical reactions, but plenty about people's reactions, and snakebite seems to have the power to intoxicate quicker and more potently than your average brew. In order to avoid the odious task of what we call "vom-mopping" or more descriptively "carrot-picking", certain drinks such as snakebite (with or without black) or over the top cocktails are banned. This ban has the added bonus of keeping out goths and people with dogs on string.

• Snakebite does not contain Blackcurrant. However, Snakebite & black does. They are not the same. I also think its more of a half and half ratio. I always thought the objection of many publicans was the clientele rather than the drink itself. I could be wrong.

• I''m fairly certain that snakebite has been banned in many pubs throughout the UK. However, having been told repeatedly by numerous British customers/backpackers here in Australia, that it is "Illegal back home" it is more than likely a reason any self respecting publican would give to ensure they don''t end up with mop in hand at closing time.I have served and consumed many snakebites in my time and it would be fair to state that people who drink it have every intention of becoming intoxicated to the point of collapse.Let''s face it, it''s not the best tasting drink available. I would also doubt that by mixing the two drinks the alcoholic content increases, as there can only be the same amount of alcohol. It is generally consumed in large quantities by people who are out on a bender and are attempting to get "leathered"

• When I was behind bar you're not allowed to 'mix' drinks unless you have a cocktail liscence. However, if you gave the customer half a pint of lager and half a pint of cider it's down to them to mix it.
