Masi Costasera Amarone della Valpolicella Classico 2007 is the nicest Amarone I’ve had.
All depends on personal preference though really. I used to love Rioja but I’ve gone right off it. Grenache, Syrah, Sangiovese, Pinot Noir, Cabernet Franc, Cabernet Sauvignon, Nebbiollo, Tempranillo…all are quite different.
