Sfera is the liter project from Italian wine importer PortoVino. All Sfera wines are certified organic farming, indigenous fermentations, unfined and unfiltered, and in a clear bottle finished with a crown cap. The current version of the Macerato bottling (macerated - i.e., a white with skin contact; a.k.a. orange wine) is grown and made by Cossentino in western Sicily, south of Palermo. It's 100% catarratto with 15 days of maceration and aging for three months in a combination of stainless steel and concrete tanks. More information here.
