100 % Barbera, which is the third most widely planted grape in Italy (guess the others? montepulciano and sangiovese).
Piedmont is surely the region where the Barbera shows its best, Asti and Alba are more famous appellations, rather than a Oltrepo’ Pavese DOC (literally land around Pavia, Beyond the Po river), but the Castello del Pozzo winery surely treated this grape as it should be.
Barbera has deep ruby colour, low tannins and high levels of acidity, it can often lead to a wine which is too fresh and fruity, still sharp and short, if not aged. Oak maturation is often used to round the corners up, but it can hide the aromatic profile, which is what barbera lovers are looking for, so it is extremely easy to get the aging process wrong.
The Barbanera winemakers decided to go for a long aging (2y) without using oak, stainless steel instead, to give a silky texture to the wine and to preserve the aromas (Primary aromas) given by the fruits, enhancing the quality of their fruits, which was outstanding in the last 5 years (generally in the north of Italy from 2015-onwards vintages are one better than the other).
Great wine, a hidden gem, excellent with charcuterie and hard cheeses, white meats, and legumes.
