Tequila
I've made it my mission to extensively research and sample alcoholic beverages of many descriptions during my distinguished drinking career, ranging from obscure real ales (I'll have a pint of Old Dog's Dick please Mr Barman), to spirits of increasing octane rating (ooh, Absinthe... Yep, that'll be with a cube of burning sugar please).

However, although I left testing Tequila until very late in life I was anxious to see what all the fuss was about so took the plunge a few years back.

Jebus...

The taste was disgusting, although I've never actually tried meths it can't be that big a step from Tequila. The first touch of the liquid on my tongue led to involuntary gurning, it made me pull a face like I'd been forced to french kiss Anne Widdecombe after she'd just finished easting sushi and raw onions.

How people can drink the stuff I'll never know but I can safely report that it makes fantastic cycle chain cleaner, making the oiliest of bike chains all shiny and like new after a through soaking in the stuff. Actually, the reside of grit and mildly toxic Pedros All Weather chain lube probably improves the flavour of Tequila no end.

My next alcoholic pet hate is Cider. Back when I were a lad (aged 15) myself and some friends purchased a two litre bottle of Woodpecker's finest and proceeded to imbibe while slumped against a tree in the local park. At first the taste was agreeably sweet, but after an hour a certain queasiness set in. To my absolute and lasting horror I quickly realised that cider tastes exactly the same regardless of which direction it's travelling through your gullet. I haven't touched the stuff in eighteen years and counting.
