The Super Tuscan is always one of the favorites of mine, friends, and family. I'd like to make it from scratch instead of from a kit. The question I have is the blend ratios. Super Tuscan is a blend of Sangiovese, Cabernet, and Merlot. But what are the ratios? 75% sangiovese, 15% cabernet, 10% merlot? Any suggestions as a starting point?
