The 2000 Barolo Marenca, the only offering on the market from this superb vineyard, is the richest and most important of the four, powerful and sweet in aroma with warm and penetrating notes of licorice, tar, and dried roses, a meaty, large-framed palate, and plush, firm tannins on its long and lingering finish.
