Made apple wine before , it does not surprisingly depend on the variety of apple to produce a decent wine though, much better to add some blackberries to the mix.
I've made wine out of apples ,pears , gooseberries , blackberries , elderberries , flowers , sugarbeet , parsnips , beetroots and a load more things to boot . Mostly it has all come out drinkable.
At the moment I have a few dozen bottles of something that I either forgot to label or the labels have come off and am slowly working my way through them. They vary from a dry white which I'm fairly sure is rhubarb to what I think is a mixed berry wine that resembles a port
Beer making is in my opinion more difficult and I've not dabbled much but have sampled some pretty foul brews from other people. A friend recently gave me some of his homebrewed beer and it wasn't good at all but on leaving he pressed a 4 pint bottle into my hands. This went straight into the garage for a few weeks until I decided to risk it again but in those few weeks it had conditioned itsself in the bottle to become quite pleasant.
I've also tried making sloe gin and last year tried crab apple vodka, all very nice.
