From SelectioNaturel:

Brothers Franco and Mario Accorsi are farmers at heart, more specifically they primarily cultivate orchards filled with local varieties of pears and apples. The farm was run by their grandfather Ezio who raised cows and produced cheese sold in the local markets around south eastern Lombardy. Today Franco and Mario have integrated orchard fruit production with several small parcels of old vineyards and focus on producing wines from near-lost indigenous varieties of lambrusco. All vineyard work is done organically.
