The term “SuperTuscan” is not an official wine designation, rather a term commonly used to refer to a wine with an international flair, generally flamboyant and dense, often powerful, tannic wines with a flavour of new oak. The term originated for innovative (and usually expensive wines) that were made outside of traditionally growing areas, with non-traditional grapes and often using non-traditional wine making. Some of the best are generally blends of Sangiovese with Cabernet Sauvignon and Merlot.
The term Supertuscan was coined in the early 1980’s and who used it first is up for debate. Regardless of who said it first, these wines continue to be produced and loved by many and the term stuck.
