Casa Belfi Frizzante Rosso
"The Casa Belfi vineyards are farmed Biodynamically and are certified organic and biodynamic by Suolo e Salute and Demeter.
The wines are made in an ancient method called Col Fondo ("with the bottom") meaning that there is sediment and/or lees present in the bottle, spurring a refermentation and adding depth and complexity to the wine. You’ll find their wines slightly less sparkling than other Proseccos as well which are made in completely different way. These are old school Italian Pet Nats." -The Living Vine
