It’s possible to make wine from just about any liquid that contains sugar, right? Sorta, at least.
So, it’s possible to make orange wine (no, not qhite grape wine where the skins are left in for a bit, but wine from oranges). Further, if you can make wine then it’s possible to make a brandy.
There are orange brandies and triple sec and so on. But none of them are an eau de vie properly made from the original fruit. They’re all varied types of booze with orange added.
So, why isn’t orange brandy made?
Human experience is such that someone must have tried – we’re in a reverse Chesterton’s Fence here, our question is why the thing doesn’t exist. So, why doesn’t it work?
