Well I've never had one sit around for over a year; 6 months was the longest it ever lasted IIRC. In your case, I would probably throw it out and buy some new stuff. I just posted in another thread about how little brake fluid costs are for most people. There's just no point risking moisture in the fluid when new fluid is so inexpensive.
