Not a bad wine and definatley a bargain, but I don't think it rates a 90. Maybe an 87-88. To me, this wine had the slightly herbal taste that so many Italian wines have (which I don't really like). That was not mentioned in the professional ratings.
The Rasteau is a fantastic CDR, hitting all the right notes.
For fans of moderately sweet Rieslings, this is a gem and a real bargain at around $20. This wine is an immediate hit at parties among wine neophytes and cognoscente.
