I am a true wine lover, always up to try something new.
A huge problem is that so many vineyards worldwide are splitting up into separate labels that it's impossible to keep track of who is who.
I tend to lean towards low-volume regionals and consider it a success if I find 1 great bottle out of a mixed case.
My best find to date was a Volnay, d'Angerville (cote-d'or), Premier Cru, 2003. I bought 2 cases for around $650 for both. It's now selling for about $65 per bottle.
Another great find is an Argentine Malbec, Andeluna 2003 that was about $15 per.
I saved labels for many years, but find much inconsistency thru the years by the smaller labels.
Wine Spectator is a valuable resource, but anything they rate over 90 immediately sees a price increase of at least $15/bottle. The best ratings are impossible to find.
For two years now I have offered my local dealer a $100/bottle bonus if he can procure certain Penfolds Grange. Alas, not yet.
