Notes from The Piedmont Guy:
"Erbaluce di Caluso Metodo Classico Brut DOCG is made from 100% Erbaluce grapes. The harvested bunches are placed in ventilated crates and stored for 4-5 days at 39° F, a process known as pre-cryomaceration. These crates enable the cold air to chill all the bunches without the occurrence of condensation. Pre-cryomaceration results in wines with a fresh fruit profile that are rounder, more balanced, and notably ageworthy. It also empowers Bruno to make minimal sulfur additions. The chilled grapes are pressed in a pneumatic tank and left in contact with the skins for 12-24 hours. Afterward, the whole-berry grapes are pressed gently but continuously in order to achieve a cleaner must."
