I brewed a light blonde ale eleven months ago. Immediately after, things got busy. By some miracle, the batch shows no sign of mold or infection. I'm assuming that oxidation and maybe autolysis will figure into the flavor and aroma. I figure that the only way to tell if it's worth bottling is... well... to bottle it (with fresh yeast, of course) and see. At best, this probably won't be a sharing beer. Anyone ever screw up like this? How did it turn out for you?
Is your beer in a plastic bucket or a glass carboy? If it is in a glass carboy I would not be concerned about oxidation. I would suggest that you taste the beer first before you bottle it. If it tastes OK then it is worthwhile to bottle it. I would recommend that you add some dry yeast to your bottling bucket for insurance; maybe after 11 months the yeast is past its prime for carbonating the beer? Cheers!
Both of the potential off-flavors you're concerned about, oxidation and autolysis, should be plenty evident if you taste the beer before bottling. +1 to JackHorzempa's advice.
