Which wine region produces a high-tannin wine known as "The Barolo of the South"?

The high-tannin wine often referred to as "The Barolo of the South" is produced in the Taurasi DOCG region. This designation is significant as Taurasi is made primarily from the Aglianico grape, which is known for its robust tannins and aging potential, similar to the Nebbiolo grape used in Barolo wines from Piedmont.

Taurasi's wines exhibit a complex flavor profile with dark fruit, spice, and earthy notes, along with high acidity, making them well-structured and capable of long-term aging. This high level of tannin and depth of flavor draws parallels to the esteemed Barolo wines, thus earning it the moniker. The region's hilly terrain and volcanic soils contribute to the distinct characteristics of the wine, enhancing the reputation of Taurasi as a serious contender among Italy's high-quality wines.

Other options, while they may produce notable wines, do not match the tannin structure or complexity associated with Taurasi wines. Basilicata, Campania, and Puglia are regions that produce a variety of wines, but they do not have a specific wine known as "The Barolo of the South," highlighting the unique standing of the Taurasi DOCG.
