The 2021 Collio Sauvignon from Russiz Superiore shows the dimension the region can produce in the variety. The wine has a great balance of fruit, herbs, and minerals — less racy and “grassy” than Sauvignon from New Zealand and more like some of those from France’s Loire Valley. Flavors of green apple, apricot, and lemon-lime are accented by touches of flinty minerality and herbs like sage and thyme. There’s a bit of creamy softness on the long finish, a reflection of aging on the leesand a small percentage of the grapes fermented in oak barrels. Aging takes place in stainless steel tanks. It is more expensive than many of the countless Sauvignons you’ll find from just about every corner of the wine world. But the price is offset by the fact that this is a singular Sauvignon Blanc that’s among the world’s best.
