I must remember not to ask strange open-ended questions. Because someone will go and find out the answer.
I asked whether it was possible to make orange wine. Wine, direct from orange juice:
Our host was, and not this type of orange wine.
He wanted to know whether it was possible to directly ferment orange juice.
Haven’t updated that one, but I did give it a shot, including Trickery.
The answer is No, Nope, Nyet. Not with yeast. And not with Aspergillus ( which would technically make it more of a sake, I guess. )
And yes.. two of the batches have seen the “Drain Cleaner” ( lab grade sodium hydroxide, but still…) treatment to get a citrate buffer at higher pH. Nope…
Other batches have seen more ….uncivilised… treatment, including two precipitation steps using Strontium salts.
( yes.. there’s an abundant natural stable non-radioactive element. Yes, they make pretty rocks. Yes, I have a couple of kilos of those. Pretty Rocks, d’uh.
It works *exactly* as a much heavier substitute for Calcium, which makes centrifuging precipitate a hella lot easier on home-brew equipment.)
You can get the yeast to grow ( -ish), and even ferment, BUT there simply isn’t enough glucose in the juice to get any appreciable amount of ethanol ( but plenty of other Nasties…).
Hitting raw juice with pectase gives a similar result: wrong kind of sugar for ethanol. ( plenty of acetone though..).
Which is basically as expected… If our medieval/renaissance forefathers couldn’t make alcohol out of the stuff, there’s little chance we can.
Even though we understand the underlying principles far better, and can point out the Why of it.
Thus Science has been Served in proving it still cannot be done, even with more advanced knowledge and understanding of the process.

So, you can make a (grape) brandy and stick some orangey bits in it (Cointreau, Triple Sec, Grand Marnier) but not an orange wine.
