Guido Porro, Barolo Vigna Rionda, 2015

Vigna Rionda is one of the most legendary single vineyards in all of Barolo, a south-facing amphitheater of calcareous-clay marl in Serralunga that has produced some of the longest-lived Nebbiolo on earth. Guido Porro is a small, under-the-radar Serralunga grower working in a deeply traditional vein, and 2015 was an early vintage from this storied cru. Fermentation runs in steel without selected yeasts, followed by thirty months of patient aging in large Slavonian oak botti. The result is everything Serralunga Barolo should be: a wine of dense, brooding structure, with the iron-and-rose perfume that announces Rionda before you can name it. A decade in, this is just opening, and there's a lifetime ahead.
