Casadei sits in Toscana, the heart of central Italy's wine country. The winery's portfolio spans both single varietals and blended expressions, drawing on grapes suited to the region's warm, structured terroir. Filare 18, a Cabernet Franc, represents the winery's work with this classic variety—a wine that has attracted attention from major critics including Wine Spectator, Wine Advocate, Wine Enthusiast, Decanter, and Falstaff. Armonia Toscana, a blend of Cabernet Franc, Alicante Bouschet, Shiraz, and Marselan, shows the winery's approach to combining varieties across the Mediterranean palette. A Viognier rounds out the range, offering a white expression. These wines reflect the character of Tuscan viticulture: structured reds with aging potential and aromatic whites suited to the region's climate.
