Which Italian wine is known as a pioneer of the "supertuscans" movement?

Sassicaia is widely recognized as a pioneer of the "supertuscans" movement because it was one of the first wines to break away from traditional Italian wine classifications and quality regulations. Created by the Bolgheri estate Tenuta San Guido in the 1940s, Sassicaia was initially made using Bordeaux varietals, such as Cabernet Sauvignon and Cabernet Franc, rather than the indigenous Sangiovese grape that most Tuscan wines relied upon.

The innovation of blends using non-traditional grapes, along with a focus on quality winemaking practices, set Sassicaia apart from its contemporaries. This approach paved the way for a new category of wines in Italy that focused on terroir and quality over adherence to strict varietal rules. As such, Sassicaia not only influenced the perception of Tuscan wines but also significantly contributed to the evolution of Italian winemaking, inspiring many other producers to experiment with similar techniques and blends.
