This third distillation takes place in a hand-forged copper still from 1911, custom-built for Isidoros Arvanitis. It lasts 13 hours and is carried out over a gentle olive wood fire. Ouzo di Plomari Adolo is the very heart of the distillation. The secret recipe for this ouzo has been passed down through generations, and the proportions have remained unchanged since 1894. To maintain the secrecy in the cellars, only one member of the team knows the herbs and seeds used in the first distillation, and another knows those used in the second.
