rookie questions

[blappie]

Does anyone have a suggestion for cataloging likes and dislikes with regard to wines? In a short span of time I've amassed voluminous opinions but generally I've forgetten by the time I'm back at the store. Labels appear familiar but I can't recall if I've sampled them or not. Should I merely get a notebook and scribble my impressions? If so, what do I write? "Yummy with nice nose?". I'm curious if there's some time-tested way or if it's a purely subjective whatever-works-for-you type deal.
Thanks in advance --
