Casa Coste Piane ★ 4.6
Loris Follador at Casa Coste Piane uses the col fondo (Rifermentato in Bottiglia) method which leaves residual CO2 from secondary fermentation as a natural preservative. No dosage and no fining are used; total SO2 is kept to a minimum consistent with VinNatur protocols. The natural sparkle and lees sediment replace the sulfite stabilization used in Charmat-method Prosecco.
Tip: Col fondo Prosecco from Casa Coste Piane is naturally lower in sulfites than standard Prosecco DOC; the lees provide antioxidant protection without added preservatives.
