#6 Greatest Ever Wine - Although Bruno Giacosa has sourced grapes from an exclusive network of growers in select areas for decades, in 1982 he also bought Falletto, one of the most coveted vineyards in the Langhe. "Falletto's limestone soil gives the wine great structure, while the south/ south-west exposure allows grapes to ripen under the best conditions, generating a long growing season," says the winemaker. Nebbiolo needs to mature slowly to give the wine its complexity. In excellent vintages, Giacosa makes one of the most prized Barolos, Le Rocche del Falletto Riserva, from the single vineyard located in the heart of Serralunga d'Alba. A wine of great structure, the Falletto Riserva also has Giacosa's hallmark of elegance and though enjoyable young, it can easily age for 30-40 years.
