I've made wine from a few different things. Fruits and flowers, mostly.
The idea, broadly, is that a wine needs acid, tannin, and alcohol. (Newby, I'm sure you know this, so it's more for other readers.)
Grapes are the wine fruit of choice, because they come with a good balance of acid, tannin, and the sugar that becomes alcohol.
Apples are not bad, but they lack sugar. If you want wine instead of cider (approx 12% alcohol by volume instead of approx 5% abv), then you have to add some sugar.
Elderberries, acid and tannin ok, even more sugar needed.
Then you get into the unusual things. Like oak leaves. They have tannin. Add acid AND sugar, and it can kind of become wine.
It's all a matter of adding what's missing. Heck, dandelion wine needs all three!
