The proprietary wine called Siena (usually a blend of Sangiovese, Cabernet Sauvignon, and Merlot) has evolved from a two-thirds Cabernet Sauvignon-based wine in 1991, to a 70% Sangiovese wine in 1994 (the finest Siena to date). The 1991 Siena is a good beginning effort. One of the bright shining success stories of California, Ferrari-Carano has a brilliant future.Tel. (707) 433-6700
