La Boheme The Missing Act The Yarra Valley's very own opera diva, Dame Nellie Melba, enchanted the world as Mimi in La Boheme. The Puccini opera, in four acts, was composed to an Italian Libretto by Illica and Giacosa. In 1957 it was revealed that the librettists had prepared an act which Puccini decided not to use in his composition. The missing act was situated in the timeline between the Act 2 and Act 3 and describes a late night, all night open-air party. A charming Cabernet Sauvignon spiced up with some characterful Sangiovese would be perfect for such an occasion!
