help with wine ratings

[njjchiro]

HELP!
I recently become interested in wines and have been happily trying many. What I'm having trouble with is understanding the rating systems used and recomendations for how long a wine my be stored. For example, I recently purchased a Spanish Rijoa and when I checked it out on Parker and WS the ratings were much different (86 WS 92Park) this seems like a very large difference. Additionally Park...said will age for 15 or more years and WS says 6 years is about it. Again it was for the same bottle of wine and the same vintage (98). So, what do you say folks....can anyone enlighten me..THANKS
