Costadila ★ 4.6
Ernesto Cattel and Adelaide Tommasi run this small estate in Rolle di Cison di Valmarino producing col fondo Prosecco from heritage Glera and traditional varieties on steep hillsides with old vine material. Their 280 slm and 450 slm altitude labels are reference-point natural Prosecco.
Tip: The numbers (280, 450) refer to altitude in metres above sea level; the higher the altitude, the more mineral and taut the wine.
