Agricola Cirelli Wines of Anarchy Pet Nat is from Abruzzo, Central Italy, made from 100% Montepulciano grapes grown organically. Native yeasts, spontaneous fermentation, and low-sulfites make this pet-nat one of the most exciting naturally sparkling wines of its kind. Bone dry, with lively bubbles and loads of juicy red fruit, this is a drink-all-day guzzler.
