Obviously our old friends at Nera winery still have some vines up here, but it is AZAGR Caven that catches the eye. Your Italian – English pocket dictionary won't help you much with this. Azagr isn't a word, but a contraction; Azienda Agricola, more or less "commercial farm".

Actually, a bit of digging shows them to be one and the same. The business was started by Guido Nera in 1940's. At the end of the 1950's his son Pietro took over and started expanding the vineyard holdings. Caven was started by brothers Stefano and Simone Nera in 1982. They describe their schtick as "Heroic" Viticulture (their quote marks, not mine) and given the expanse of their holdings, I won't argue.
