98-Points by James Suckling. 
A blend of fruit from three estate-owned plots in the Bricco di Treiso cru, this aged for 30 months in large oak botti, with a small portion in French oak for 18 months. It shows the imprint of 2015’s warm, dry growing season in its flavors of ripe red and black berry fruits, crushed violets, licorice, and spicy notes give way to a medium to full-bodied Barbaresco with plenty of angular yet ripe tannins, good acidity, abundant mid-palate depth, and a great finish. Best from 2019 through 2038.
 
Pio Cesare has been producing wine for more than 100 years and through generations. The tradition began in 1881, when Pio Cesare started gathering grapes in his vineyards and purchasing those of some selected and reliable farmers in the hills of Barolo and Barbaresco districts.
Pio Cesare limits its production by using only the most mature and healthy grapes. The ripening of the grapes is carefully monitored and the harvest is rigidly controlled with each grape selected by hand.
Today, the estate is managed by Pio Boffa, great-grandson of Pio Cesare. Under his stewardship, the wines of Pio Cesare have become famous throughout the world. Great strides have been made in quality, and single vineyard offerings have dazzled the wine press.
A wine that most perfectly conveys the spirit and essence of its place, Barbaresco is true reflection of terroir. Its star grape, like that in the neighboring Barolo region, is Nebbiolo. Four townships within the Barbaresco zone can produce Barbaresco: the actual village of Barbaresco, as well as Neive, Treiso and San Rocco Seno d'Elvio.
Barbaresco’s soils are approximately of the same two major soil types as Barolo: blue-grey marl of the Tortonion epoch, producing more fragile and aromatic characteristics, and Helvetian white yellow marl, which produces wines with more structure and tannins.
Nebbiolo ripens earlier in Barbaresco than in Barolo, primarily due to the vineyards’ proximity to the Tanaro River and lower elevations. While the wines here are still powerful, Barbaresco expresses a more feminine side of Nebbiolo, often with softer tannins, delicate fruit and an elegant perfume. Typical in a well-made Barbaresco are expressions of rose petal, cherry, strawberry, violets, smoke and spice.  Bottle aging adds more savory characteristics, such as earth, iron and dried fruit.
