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.
