Burgundy has some massive ongoing threads, you can read through and start to calibrate your palate.
As with reviewers, you should never go out and buy something just because someone on here is raving about it. But, the advantage to this place is that you can have ongoing conversations with people over time and find out whose palate matches yours, and in which ways. Then you will have very useful sources of information with the added benefit of being able to meet in person and drink together!
