You can only leave it for so long if you put an air valve on it while your gone. If you put on an air valve too early it might clog up and burst your carboy. ( Bad idea)
Let your wine go at least until spring. 2 months isn't going to make it worth drinking.
Is there a way to measure the approximate alcohol level in my wine if I have a refractometer but forgot to measure the Brix sugar content before the fermentation started?
