From the first sniff and sip, I find this a special wine. It's a blend of Chardonnay, Sauvignon Blanc, Riesling and Nascetto grapes grown in the middle of Barolo territory. The wine was (is) so good that vintners were unwilling to replace these white grape vines with more lucrative Nebbiolo ones.
Medium yellow color. Exciting nose that keeps getting more complex as the meal progresses. Reasonably full bodied with rich but intense and tightly focused aromas and flavors. I don't think there is much Riesling in the blend, but it has a strong presence in the complexity on the back palate.
