There is one particular drink that I will never forget nor will it ever pass my lips again. But first the second least pleasant drink I've tried and that has to be Strega.

Strega, meaning Witch, is an Italian herbal liqueur the colour of early morning urine after a night of drinking, well, probably a bottle of Stregga. As an aperitif or digestif it is foulness with a hint of syrupy sweetness. I have managed to drink it in company where it would have been rude not to and I have a bottle downstairs that I like to ply unsuspecting dinner guests with. Always a giggle that is.
But Strega is liquid gold compared to this...

Unicum (ooni-combe phonetically) is from Hungary and it is the single most vile and revolting drink I have ever tasted. Think of Ford and Arthur's reaction a few moments after drinking a Pan-Galactic Gargle Blaster and you will understand the viciousness with which this drink assaults your taste buds. Unlike the reaction to a PGGB however the reaction from drinking Unicum happens the instant it touches your lips. In fact, before that, your nostrils are protesting of GBH from what you think could be a caustic vapour and the smell of burning hair rising from the tiny amount of dark liquid in your glass. Surely not? If your brain doesn't tell you not to put any of this into your mouth by this point it will soon tell you to remove it when you do. A cocktail of creosote and tarmac laced with sulphur and with a hint of bromine has that kind of effect on a person and that description is putting things mildly. Later you'll be looking in the bathroom mirror, whilst cleaning your teeth for the tenth time trying to remove the evil taste that still lingers in your mouth, and you'll realise that the smell of burning hair was not the Unicum but your very own, now singed, nostril hairs.
If you're a brave sort that likes a tipple of something a bit different then check out Unicum. Go on.. .. .. I DARE YA!
Anyone else already tried Unicum? Any other revolting drinks to add? Alcoholic or otherwise.
