Modern ouzo distillation largely took off in the 19th century following Greek independence, with much production centered on the island of Lesbos, which claims to be the originator of the drink and remains a major producer. In 1932, ouzo producers developed the method of distillation using copper stills, which is now considered the canonically proper method of production. One of the largest producers of ouzo today is Varvayiannis (Βαρβαγιάννης), located in the town of Plomari in the southeast portion of the island, while in the same town Pitsiladi (Πιτσιλαδή) high quality ouzo is also distilled. Another producer on the mainland of Greece is Ch. Pavlides Brothers. (Older people in Lesbos, still refer to ouzo as "raki").
