As Bernard says, protection from oxygenation is very important. At the very least, keep your airlock filled.
I bottled a mead last week that had been sitting undisturbed for several months (since late September or early October). It looked incredibly beautiful, and also tasted very, very good. I expect it to get even better as it ages.
The only "fly in the soup" was that it was just starting to get an off-aroma from sitting on the yeast; the smell isn't exactly like soy sauce, but that's the closest thing I can think of. Luckily, it did not affect the taste; but if I would have waited much longer, it might have. Hopefully, yours won't have this problem.
The moral of the story, in my mind: Make bloody-well sure that you rack it at least once, after a couple of months, to get it off the major portion of the yeast etc. Even better, try not to forget about it, like I did.
