History

Considered by some experts as original birthplace of Nebbiolo grape. In 19th century Boca was "the top" - Barolo at that time was light frizzante at 8% alcohol, while Boca was always made to age. DOC established 1969. Cà Finazzi started producing in 18th century. Region declined from 40,000ha (more than Champagne's 34,000ha) to mere 3 commercial hectares at lowest point due to mildews, phylloxera, WWI/WWII. Guido and Cristiana Sertorio bought old Cà Finazzi winery 1980, revived as Podere ai Valloni - first registered Boca DOC producer, first vintage 1983.
