Casa Coste Piane ★ 4.7
Loris Follador's three-hectare estate in Santo Stefano di Valdobbiadene is the reference point for col fondo (cloudy, pet-nat style) Prosecco. His 'Fontanasanta' Rifermentato in Bottiglia has been the standard-bearer for traditional method Prosecco and is produced in tiny quantities.
Tip: Serve the col fondo lightly chilled and without decanting; the cloudy bottle is intentional and the lees add texture and complexity.
