Picollo Ernesto is a well-regarded, family-owned winery in Rovereto di Gavi, Piedmont, Italy, famous for its crisp, aromatic Gavi DOCG white wines made from the native Cortese grape, offering flavors of lime, green apple, and wet stone with zesty minerality, often appealing as an alternative to Pinot Grigio and pairing well with seafood. The estate, established in 1945 by Lorenzo Picollo, focuses on traditional, organic farming with old vines and stainless steel fermentation for fresh, vibrant expressions of the terroir, now run by the third generation.
