In the finest vintages, such as 2016, Alfio makes a tiny quantity of Riserva, with just 2,500 bottles produced in 2016. This all comes from the Mossino vineyard, their highest plot, planted in an amphitheatre that points due south. A blend of old and young vines, and a little of the high-acid Rossola, creates a wine of incredible focus, purity, and intensity. The nose here is so mineral, with a slight iodine note and blood orange, and a very long finish.
