It’s best to think of Super Tuscans as an idea rather than a specific wine style, as they can range from 100% cabernet sauvignon to 100% sangiovese, with lots of permutations in between. That said, they tend to be big and full-bodied, often with flavors which remind us more of California and Bordeaux than the neighboring regions of Chianti and Brunello di Montalcino. It’s also a term used for a group of wines from the Chianti Classico region who went against the Italian wine law and made wines using 100% sangiovese. Those wines are much lighter in style and an entirely different type of wine than the big and bold ones. There’s no way to tell the difference other than knowing the producer's style and grape blend.
