Can I drink it now?

[WineViking]

My wife and I are starting to appreciate wine, and are quickly realizing how little we know, and how naive we have been for so very, very long. There seem to be quite a few experts here. Learning all this seems intimidating, but I guess we'll start with some baby steps.

I am right now drinking a Virginia Voignier (Rappahannock Cellers, in case there are any Virginians here) from 2005. Have I committed a mortal sin by opening this bottle so early? I understand that some wines are being made now for earlier drinking, but how does one learn which ones are OK to immediately drink, and which ones really should be stored for a couple or more years before drinking? Can a Voignier be immediately drunk? Drinking this now, I guess I would say it is OK, but not as fruity as I would have expected. I am wondering if maybe I failed to let it sit an appropriate amount of time to appreciate it.

This particularly bottle was purchased during a wine tour in the Virginia "wine country", and wasn't particularly cheap, though not too pricey...I believe something like $18 bucks.

Any insights are greatly appreciated. Thanks.
