I have a hideous memory of very cheap "cider" from a shop in Bristol in the late 70s. 5L for £1.20 in a "bring your own" plastic can, the stuff was cloudy, flat and only made drinkable by adding fizzy lemonade. Seemed OK, ish, but the following morning..dear God, I could have given up alcohol, but turned to home brew beer.
I've never, ever, touched cider since.
Peter J, you took back in time. I was never a drinker, not even a social drinker but when I was young(19 or 20) I had my "experience" with cider. I like my drinks on the sweet side but that night, a Christmas night...all I remember was trembling the whole night long, sleeping by moments and in the morning...1.000.000 football supporters chanting, clapping and jumping inside my head. It was that bad. I have barely touched cider ever since.
