The Gallina vineyard is planted with Nebbiolo for Barbaresco, with Pinot nero for Metodo Classico and with Pinot Grigio, Riesling italico and Pinot Bianco for a Castelborgo Brut made using the Charmat method. The idea to make a Metodo Classico was born out of the discovery of a long and deep ‘infernotto’ corridor which runs from the castle’s cellars well into the depths of the hill, where temperatures in the summer do not exceed 13-14 C and in the winter do not go below 6-8 C, the ideal temperature for the production of such a fantastic and challenging wine.
