Giacomo Conterno is an Italian estate just outside Monforte d'Alba in Piedmont, in the south of the Barolo DOCG zone. It is best known for two great Barolos: the Cascina Francia and the Monfortino Riserva, both of which are long-lived and earthy.
In 1908, Giovanni Conterno opened a small tavern in the village of San Giuseppe, making Barolo to supply the business. The first Riserva was bottled around the time of World War I, and was one of the first examples of producer-bottled Barolo at a time when most were sold in bulk for early consumption. Giovanni's son Giacomo took over when his father died in 1934, and ran the estate until his death in 1961. His sons, Giovanni and Aldo, worked together until the latter left in 1969 over stylistic differences, forming his own estate. Roberto Conterno, grandson of Giacomo, took charge in 2003.
