Guido Porro’s Santa Caterina is a perfect example of the finesse, complexity, and longevity this cru can achieve, specifically when crafted via traditional production methods such as spontaneous fermentation, long macerations, and extensive aging in enormous Slavonian oak casks. These techniques produce a Barolo with delicate and nuanced aromas backed by a deep, chewy structure that promises a slow and steady evolution throughout the years—twenty years or more, if you so wish.
